Dynamic, Efficient and Luxurious
Woodcliff Lake, NJ – October 14, 2011 11:15 am EDT … With the
announcement of the sixth generation BMW 3 Series Sedan, the benchmark by
which all sport sedans are measured just got raised. The pioneering history of
the 3 Series serves as inspiration for the new sports sedan, whose powerful
styling represents a fresh interpretation and conscientious development of
traditional BMW design cues. It will not only set new standards for performance
and handling but also for luxury, technology and efficiency as well.
The all-new BMW 3 Series Sedan arrives in US showrooms in February 2012 as
a 2012 model.
The new BMW face, with elongated headlights reaching along as far as the
BMW kidney grille, emphasizes the new BMW 3 Series’ sense of width and
strengthens its athletic overall profile. The sixth generation of the 3 Series has
grown moderately in size compared to its predecessor, with its wide track (front
+ 37 mm/1.46 in., rear + 47 mm/1.85 in.) particularly prominent, and the car’s
length (+ 93 mm/3.66 in.) and wheelbase (+ 50 mm/1.96 in.) also accentuates its
sporting allure. Inside the new BMW 3 Series Sedan, the rear passengers will
appreciate the noticeable increase in space made possible by the larger
dimensions. And the BMW 3 Series range is now also available in a trio of trim
and equipment variants – the Sport Line, Luxury Line and Modern Line. Each
presents its own individual take on the character of the sports sedan, with
exclusive, high-quality material combinations and unbeatable build quality
underlining the premium ambience of the new range.
Drive and chassis technology have always been key areas of expertise for the brand,
and agility and driving dynamics remain outstanding attributes of the new
BMW 3 Series Sedan. The new car belies its larger dimensions with an equipment
equalized curb weight 88 lb (40 kilograms) below that of its predecessor.
A choice of two muscular, refined and efficient engines – which both feature new
BMW TwinPower Turbo technology – will be available for the new
BMW 3 Series Sedan in the US market. In addition to the already successful
6-cylinder N55 engine powering the 335i, customers can also opt for the new
turbocharged 4-cylinder (N20) variant in the BMW 328i. This latest-generation
engine, initially introduced in the 2012 Z4 sDrive28i, rewards the driver with both
a dynamic driving experience and significantly reduced fuel consumption.
The innovative 8-speed automatic gearbox – which is a first in the segment –
opens up a whole new level of driving experience. It can be specified in
combination with either the 328i or the 335i and includes the new Auto Start-Stop
function. Compact and exceptionally efficient, it allows the new BMW 3 Series to
match or outperform models fitted with the standard six-speed manual gearbox
in terms of fuel economy. The new 8-speed automatic brings together shift
comfort, dynamic performance and efficiency of the highest order, making it the
perfect partner for the new sedan’s dynamic potential.
As components of the BMW EfficientDynamics technology line-up, the
Auto Start-Stop function, Brake Energy Regeneration, and need-based operation
of ancillary components (including an on-demand air conditioning compressor)
also play their part in reducing fuel consumption. Added to which, the new
Driving Dynamics Control switch, which allows the driver to choose between
Comfort, Sport, Sport + and ECO PRO Mode, gives both models the potential to
further improve these figures. This ECOPRO Mode helps drivers maximize fuel
economy through their driving style, thereby enabling them to increase the
distance they can travel between visits to the pumps. BMW will add another
cutting-edge engine to the line-up in 2012, when the BMW ActiveHybrid 3 will
premiere.
BMW ConnectedDrive offers an unmatched combination of available driver
assistance technology and mobility systems for the new BMW 3 Series range. A
new arrival in the premium mid-size segment is the latest-generation full-color
Head-Up Display, which projects key information – in sharp resolution – onto the
windshield so it appears directly in the driver’s field of view. Also available is
Surround View with Side View and Top View, which gives a bird’s-eye
perspective of the vehicle and the area around it. In addition, an available
Parking Assistant system helps the driver to parallel park. Among the other
assistance technology available under the BMW ConnectedDrive banner are the
Active Blind Spot Detection System and Lane Departure Warning System with
camera-based Collision Warning system, which are offered for the first time in a
BMW 3 Series. A Navigation System with Real-Time Traffic Information (RTTI)
and an innovative comfort access function allowing hands-free opening of the
trunk lid are all included on the options list.
Design.
All in all, the innovative body structure and intelligent lightweight design concept
of the new BMW 3 Series Sedan ensure that it is now larger and safer, but –
depending on the engine specified – also lighter. The dynamic proportions and
athletic overall impression of the new 3 Series bring the sporting character of this
hugely successful model into even sharper focus.
The BMW 3 Series Sedan is an iconic figure in the sports sedan segment and
over the years has come to symbolize the aesthetic appeal, dynamics and
sporting capability of BMW. With its dynamic lines and athletic overall presence,
the sixth generation of the world’s best-selling premium vehicle highlights the
sporting character of the brand’s mid-size model. Although the new BMW 3
Series has grown moderately in all dimensions compared to its predecessor, it
retains a perfect balance of sportiness and elegance. As in previous generations,
the sedan’s dynamic proportions are shaped by the sweeping hood, short front
overhang, long wheelbase and set-back greenhouse, typical of BMW.
Striking face with precise contours and multi-faceted surfaces.
The wedge shape of the new 3 Series’ silhouette and its wider track
underline the sporting appearance of the new BMW. By clearly accentuating the
width of the car, the multi-faceted surfaces of the expressive front fascia give the
BMW 3 Series a more athletic face than ever. A wide, squat interpretation of the
upright, slightly forward-slanting BMW kidney grille emphasizes the assured
presence of the new BMW 3 Series. LED accent lights positioned like eyebrows
above the striking twin headlights with corona rings (if Xenon Headlights are
specified) lend an extra intensity to the classic BMW focused look. Clearly
defined headlight surrounds now extend up to the frame of the kidney grille,
merging the headlights and grille of the new BMW 3 Series Sedan into a single
stylistic unit and adding further emphasis to the car’s broad-set stance. The
BMW 3 Series replaces the central air intake of its predecessor with two larger
intakes, which are positioned underneath the headlights to the outer edges of the
front fascia and add extra depth to the car’s sporty styling. On the far left and
right of the main ducts are small vertical intakes which help create the “Air
Curtain.” This new technology improves air flow around the front wheels,
enhancing aerodynamic efficiency and reducing fuel consumption at higher
speeds.
The closely spaced, squat openings of the kidney grille, with their eye-catching
surrounds, form the most prominent element of the new BMW 3 Series Sedan’s
front design. This is also where the precise lines of the heavily contoured hood,
spawned by the roof pillars and flowing over the full length of the hood, come
together on the their journey towards the road. The result is a front that appears
lower-slung, giving the BMW 3 Series a clear sporting edge when viewed head-
on.
Precise lines produce a stretched silhouette and enhance the car’s
dynamic impact.
Powerfully taut surfaces with sweeping lines dominate the side view of the BMW
3 Series Sedan, stretching the car visually and lending extra verve to its dynamic
stance. The flanks of the car are shaped by an eye-catching double character
line running alongside each other. The higher character line emerges out of the
low-slung nose and flows over the front wheel with an understated sweep, in a
nod to the sedan’s fleetness of foot. The second character line develops lower
down behind the front wheel and follows a delicately arching path towards the
rear. Together, they reinforce the dynamic wedge shape of the car’s flanks. As
well as providing a discreet increase in muscularity in the rear section below the
character line, these styling cues also create vivid light and shade effects, which
draw further attention to the car’s wide track.
The striking interpretation of the hallmark BMW Hofmeister Kink at the base of
the C-pillar, injects the silhouette of the new 3 Series with even greater élan.
Alongside it runs a fine contour line from the roof pillars into the rear deck lid,
giving the roof an even lower appearance from the side. The resultant sense of
sporty yet elegant lightness spreads all the way down the sedan’s sides, with the
slightly rising shade line low down on the heavily contoured side skirt adding
further emphasis. The large light surfaces above the side skirt serve to enhance
the lightness of the car’s flank lines.
Contrasting light surfaces imbue the rear with brio and energy.
The strong horizontal lines of the rear – including rear lights in customary
BMW L-shaped design positioned at the outer edges of the rear – accentuate the
broad face of the wheels and wide track of the new BMW 3 Series Sedan. The
low-set reflectors guide the vertical lines flowing out of the greenhouse over the
rear lights to the wheels, lending visual emphasis to the car’s consummate road
presence. Traditional BMW 3 Series design traits include the two lines below the
rear spoiler and above the bumper, which frame the rear stylistically. Richly
contrasting light surfaces give the rear end of the new BMW 3 Series Sedan a
fresh dynamic flair, while the interchanges between smoothly flowing surfaces,
precise lines and defined edges inject brio and energy.
The interplay of surfaces and lines fills the interior with life.
The interior of the new BMW 3 Series Sedan is straight out of the BMW design
handbook. The driver-focused cockpit wraps around the driver and puts all the
important controls within easy reach. The cockpit is angled towards the driver by
seven degrees. The ingenious layout of the front cabin incorporates the driver-
focused cockpit as part of its natural design – i.e. without excluding the front
passenger. The surfaces and lines flow over the instrument panel towards the
front passenger side of the cabin, where they form a smooth, protective border.
In the driver’s area all the lines converge on a single point behind the steering
wheel and guide the eye towards the road.
The cockpit’s four circular dials (fuel gauge, speedometer, tachometer and oil
temperature gauge) come with a black panel display. Positioned on the
horizontally structured instrument panel, the freestanding iDrive monitor with
slim, transreflective, high-resolution display recalls the latest flatscreen
televisions normally found in living rooms rather than cars.
On the driver’s side of the deliberately asymmetric center tunnel, a different trim
surface and graining mark out the active driving elements of the interior, while
the trim surface on the front passenger side exudes a pleasingly elegant air.
Positioned centrally on the center console within easy reach of both the driver
and the front passenger is the standard iDrive Controller.
More space, wide variety of storage compartments, even greater
practicality.
Passengers in the rear of the new BMW 3 Series Sedan will enjoy significantly
more space than in the outgoing model. The car’s larger dimensions ensure rear
passengers are welcomed by 0.71 in. /18 mm of extra legroom inside the doors
as they climb aboard. Behind the fully contoured front seats, 0.6 in / 15 mm of
additional knee room and 0.31in. / 8 mm of extra headroom further enhance the
passengers’ comfort on the road. Backrest nets offer additional accommodation
for small items, reflective vests and road maps. Larger pockets in the front doors,
whose lines and surfaces open up towards the instrument panel, now have
space for drink bottles up to one liter in size. Added to which, two large drink
holders are now integrated into the center console ahead of the gearshift lever. If
desired, the cupholders can be swapped for an oddments tray, which is stored in
a special area of the glove compartment when not in use. The new sedan offers
480 liters of luggage capacity, 20 liters more than the outgoing model in DIN
measurement protocol. And an innovative and practical solution allows extremely
convenient access inside. If the optional Comfort Access is specified, the trunk
can be opened hands-free and without needing to use a key. For example, if the
driver approaches his new 3 Series with both hands full, all he/she needs to do is
move his/her foot around underneath the bumper to trigger the opening
mechanism for the trunk lid (see also BMW ConnectedDrive). The luggage
compartment can hold as much as three golf bags, or a pram and chassis
inserted over a remarkably low trunk sill that is a mere 26 inches high (66 cm).
Standard securing hooks hold the items firmly in place, while a storage tray
under the load compartment floor and a deep storage compartment on the left-
hand side accommodate small oddments. For bulky items, the optional Through-
Load includes a folding rear seat bench to allow flexible transport solutions. The
40:20:40 split rear backrests offer unbeatable versatility when you need to carry
passengers and long items, such as several pairs of skis or snowboards, at the
same time.
Three equipment lines shine the spotlight on the car’s distinct character
traits.
High-quality material combinations and unbeatable build quality underline the
premium ambience of the new BMW 3 Series Sedan. The materials and color
concept of standard model accentuate the sporting character of the car, but a
large selection of colors and upholstery variants also offer scope for various
other options. From the basic matte satin silver surface treatment to the warm
look of fine burr walnut wood, all trim surface options can be combined with
either the leatherette or one of two leather upholstery colors.
In addition to the standard trim level, the new BMW 3 Series Sedan can now
also be specified with any of three equipment lines or an M Sport Package.
Customers can therefore adapt the appearance of their car to their personal
lifestyle and preferences – in their own way and with eye-catching results. The
Sport Line, Luxury Line and Modern Line each emphasize the different sides to
the new BMW 3 Series Sedan’s character in their own individual way. The
exclusive, carefully coordinated equipment features embrace both exterior
design elements and the selection of materials and colors for each model. In
terms of value, design coherence and expressiveness, the new BMW Lines go
far beyond existing packages in the segment.
Sport Line: With eye-catching exterior features in high-gloss black, this new line
accentuates the dynamic appearance of the BMW 3 Series Sedan. Eight heavily
contoured high-gloss black kidney grille slats in a chrome-colored surround give
the front end of the car a particularly sporty and alert look. The black inserts in
the front apron make the air intakes appear larger and lend extra emphasis to
the muscular wheel arches. Bi-color, double-spoke design 18-inch light-alloy
wheels provide the athletic looks to match. Meanwhile, high-gloss black painted
exterior mirrors and the standard high-gloss black B-pillar and window trim add
an extra sporting flavor to the flanks. A black trim strip on the lower crease
underlines the width-enhancing effect of the rear styling, while the black chrome
exhaust tips rounds off the exterior’s sporty appearance. The sporty and
exclusive ambience of the interior is expressed by contrasting black and red
accents. Red trim rings, red scales in the circular dials, red stitching on the
sports steering wheel and a base trim strip in high-gloss black with coral red
accent strips all underline the sporting ambience of the cockpit. The standard
sports seats can be specified in a choice of two upholstery styles and three
colors. The ignition key for Sport Line versions of the new BMW 3 Series Sedan
is identified by its black finish and red detailing.
Luxury Line: The discreet high-gloss chrome elements of this line lend the
exterior of the BMW 3 Series Sedan a particularly elegant and exclusive appeal.
The BMW kidney grille with 11 fine chrome slats, two slightly offset chrome trim
strips in the front apron air intakes, and a high-gloss chrome trim strip running
horizontally above the air scoop give the front a striking appearance. As with the
Sport Line, the B-pillar and window guide come in high-gloss black, and the
window frame and weather strip are in chrome. Special 18-inch light-alloy wheels
in multi-spoke design accentuate the stylishness of the new BMW 3 Series
Sedan when viewed side-on. From the rear, the new Luxury Line is easily
identified by its exquisite, high-gloss chrome trim strip – which extends across
the full width of the rear apron – and its chrome exhaust tips. Chrome elements
also catch the eye inside the Luxury Line variant. This is the only line which
gives the radio and air conditioning units a chrome surround. High-gloss wood
trim (with stylish inlays also available) and seats with distinctive stitching and
leather upholstery in three classically elegant colors highlight an inviting,
exclusive ambience. The ignition key for Luxury Line versions of the new BMW 3
Series Sedan can be identified by its black finish and chrome detailing.
Modern Line: In contrast to Luxury Line models, the avant-garde trim elements
included in Modern Line versions of the new BMW 3 Series Sedan are all in satin
aluminum, underlining the contemporary character of this line. The BMW kidney
grille, with 11 satin aluminum slats, and double trim strips for the air intakes in
the same color give the front end of the new BMW 3 Series Sedan a particularly
contemporary, classy touch. The high-gloss black B-pillar and window trim of the
Modern Line blend smoothly with the satin aluminum trim elements at the front
and rear. 18-inch turbine-style light-alloy wheels strengthen the future-focused
concept of this equipment line. The harmonious lightness of the interior
dispenses with strong contrasts. Instead, with a light upper side to the dashboard
and a steering wheel in Dark Oyster, it generates an all-new ambience. Leather
upholstery in Oyster or Black, and a choice of three trim surfaces with accent
strips in pearl-effect chrome, further enhance the appealing interplay between
materials. A trim element with three-dimensional structure and open-pored wood
lays on a whole new feast for the fingertips. Modern Line versions of the new
BMW 3 Series Sedan are marked out by the oyster-colored ignition key with matt
silver detailing.
M Sport package: The M Sport package brings the ultimate in sporting
makeovers to the new BMW 3 Series. An all-new aerodynamic package for the
exterior clearly sets cars specified with this package apart from the base model
and the three lines. 18 and 19 -inch light-alloy wheels in hallmark M design,
M Sport suspension, a black kidney grille and BMW Individual High-gloss
Shadowline trim give the car that typical M look. The theme continues inside the
car with sports seats boasting distinctive upholstery choices, trim elements with
blue accent strips, an M Short-shifter (in models with manual gearbox), M door
sill covers, an M driver’s footrest and the new M leather steering wheel.
New dimensions in driving pleasure and dynamic performance: Sporty power
delivery, outstanding efficiency and enhanced ride comfort. The sixth generation
BMW 3 Series sports sedan offers top-level agility and driving dynamics, and
they combine all this with new levels of comfort. At the same time, there is no
change to the proven basic concept comprising high-performance engines, a
sporty chassis and a rigid, lightweight body. After all, over the past 35 or more
years, drivers have come to expect dynamic, sporty driving enjoyment as a
matter of course in a BMW 3 Series model, while powertrain and chassis
technology rank as a core strength of the brand. A longitudinally mounted
engine, rear-wheel drive and a balanced (50:50) weight distribution are a formula
that makes the BMW 3 Series the sportiest sedan in its segment.
At launch, the new BMW 3 Series Sedan will be offered with two high-torque,
refined and fuel-efficient engines, both feature the latest BMW TwinPower Turbo
technology. They comprise the familiar 6-cylinder inline engine and a new-
generation 4-cylinder engine. Both engines offer impressive driving dynamics
coupled with substantially reduced fuel consumption and emissions. At first sight
contradictory and conflicting technical objectives have been ingeniously resolved
by BMW. For example, the dynamism goes hand in hand with outstanding
performance on the cost and environmental front, since emissions for both the
engines are well within the US ULEV II limits. And the new Driving Experience
Control switch with ECO PLUS Mode, which is available for all engine versions,
provides the opportunity to extend these savings even further.
Power is delivered to the rear wheels either via a standard 6-speed manual
transmission or, optionally, via an 8-speed automatic – currently the only such
unit in this segment. The automatic, which can be combined with either engine,
is so efficient that it is able achieve lower fuel consumption and emissions than
with the manual transmission on the EU test cycle (EPA test figures will be
announced closer to the US on-sale date). Both the manual and the automatic
models are equipped with the Auto Start-Stop function for further savings.
Advanced suspension technology, featuring a large number of light-alloy
components and new tuning, along with Servotronic speed sensitive power
steering, low vehicle weight and a balanced weight distribution top off a dynamic
package, making the new BMW 3 Series Sedan an exemplar of sporty handling
combined with increased comfort.
BMW 328i: New 4-cylinder gasoline engine with TwinPower Turbo
technology sets a new benchmark for driving dynamics and efficiency.
With the launch of the new sports sedan, an ultra-modern 4-cylinder engine will
make its debut in the BMW 3 Series. In keeping with the dynamic overall theme
of the new BMW sports sedan, this new-generation turbocharged engine offers
plenty of power and performance, responsive acceleration, powerful torque, a
high rpm ceiling and low weight. The new 4-cylinder engine, which provide
noticeably livelier power for maximum driving enjoyment, also comes with lower
fuel consumption than its predecessor.
The state-of-the-art, lively 2.0-liter engine marks a return to the popular sports
sedan’s roots – it was with lightweight, high-performance 4-cylinder engines in a
similar vein that the BMW 3 Series made its debut back in 1975, with the first
6-cylinder engines for this series making their appearance at the 1977 Frankfurt
Motor Show. A 6-cylinder continues to top the engine line-up in the new BMW 3
Series.
The significant upgrade in power and efficiency is chiefly down to the use of
BMW TwinPower Turbo technology, which combines High Precision Direct
Petrol Injection, Double-Vanos variable camshaft timing and VALVETRONIC
variable valve timing along with twin-scroll turbocharging. On the new-generation
4-cylinder engine, this world-exclusive technology package from BMW again
provides a very efficient way to extract more power from the engine, rather than
taking the route of a much larger displacement and, in the process, adding to the
weight and therefore to fuel consumption. This explains why the more dynamic
performance and driving enjoyment does not come at the expense of higher fuel
consumption and emissions.
The new BMW TwinPower Turbo 4-cylinder’s displacement of 1,997 cc delivers
maximum power of 180 kW/ 240 hp at 5,000 rpm while, thanks to twin-scroll
turbocharging, the maximum torque of 260 lb-ft is developed at just 1,250 rpm
and remains constant up to 4,800 rpm. These statistics translate to
commensurately dynamic performance: The new BMW 328i accelerates from 0
to 60 mph in just 5.7 seconds, on its way to an electronically governed top speed
of 130 mph, 155 mph with Sport Line. The engine responds instantly when the
driver demands more throttle, and the vigorous and almost linear power delivery
from only slightly above idle, which continues all the way into the higher rpm
range, is duly impressive.
BMW TwinPower Turbo technology in the new 4-cylinder engine.
This new engine is the most powerful in a new generation of 4-cylinder engines
designed in accordance with the BMW EfficientDynamics strategy, which aims to
combine increased driving enjoyment with reduced fuel consumption and
emissions. In technical terms, this new 4-cylinder engine is modeled on the
current multi-award-winning 6-cylinder inline engine with BMW TwinPower Turbo
technology (N55), which is the benchmark in its class for dynamic power delivery
and impressive efficiency. This world-exclusive technology combines High
Precision Direct Petrol Injection, Double-Vanos variable camshaft timing and
VALVETRONIC variable valve timing with twin-scroll turbocharging.
These features give the new BMW 328i the sort of power which with a naturally
aspirated engine would require more cylinders and larger displacement. At the
same time, with its all-aluminum crankcase, this engine is lighter and more
compact than a 6-cylinder engine of equivalent power. This has obvious benefits
for driving dynamics: the reduced load on the front axle gives this
BMW sports sedan greater agility and further improved steering and cornering
characteristics.
Twin-scroll turbocharging.
The new 4-cylinder engines also feature twin-scroll turbocharging. This means
that the exhaust stream from cylinders 1 and 4, and the exhaust stream from
cylinders 2 and 3, follow separate spiral-shaped paths to the turbine wheel. This
reduces exhaust back-pressure at low engine rpm, allowing the energy of the
exhaust gas pulses to be utilized as efficiently as possible. The result is instant
throttle response and fast-revving performance which BMW drivers can instantly
translate into driving pleasure.
VALVETRONIC, Double-Vanos and High Precision Direct Injection.
The combination of a high power output and a simultaneous reduction in
emissions is achieved by VALVETRONIC variable valve timing and Double-
Vanos variable camshaft timing. The latest generation of the VALVETRONIC
system features a faster-acting, optimized stepper motor with integrated sensor.
Seamlessly variable control of intake valve lift dispenses with the need for a
throttle butterfly. Instead, the air mass is controlled inside the engine, resulting in
faster response. At the same time, pumping losses have been reduced to a
minimum.
The excellent efficiency is also down to the High Precision Direct Injection
system. Centrally positioned between the valves, solenoid injectors precisely
control the supply of fuel. The fuel is injected very close to the spark plug, with a
maximum injection pressure of 200 bar (2900 psi), resulting in clean and
homogeneous combustion. The cooling effect of the directly injected fuel also
results in a higher compression ratio than on port injection engines, bringing
further efficiency improvements.
Exceptional performance assisted by innovative design features.
The exceptional performance of the new engine is also due to various innovative
features of the core engine. For example, twin balancer shafts positioned at
different heights result in optimized vibration absorption, while a centrifugal
pendulum absorber integrated in the dual-mass flywheel brings a noticeable
reduction in irregular running at low engine rpm. The driver can therefore make
full use of the strong low-end torque without sacrificing smoothness. These
factors all help to explain why the new 2.0-litre 4-cylinder engine achieves
refinement, noise and vibration of a kind that was previously confined to
BMW 6-cylinder engines.
BMW 335i: Inline 6-cylinder engine with beefy power delivery, strong
torque and superb refinement.
Fans of large 6-cylinder engines have a treat in store too. The inline 6-cylinder
engine (N55) in the new BMW 335i will impress performance-minded drivers with
its effortless power, exceptionally fast-revving temperament and outstanding
refinement. The N55 has been setting standards from the start, as the pioneer of
a new generation of engines in which BMW TwinPower Turbo technology with
High Precision Direct Injection and VALVETRONIC variable valve timing plus a
twin scroll turbo made its debut.
Thanks to intensive fine-tuning of the engine, BMW’s engineers have now further
reduced the fuel consumption and emissions of the predecessor, while at the
same time maintaining its high performance. With a maximum power rating of
225 kW/ 300 hp at 5,800 rpm, the 3.0-litre 6-cylinder unit reflects the sporty
personality of the BMW 3 Series and helps this sedan deliver brilliant
performance. And the high peak torque of 300 lb-ft, on stream between 1,200
and 5,000 rpm, ensures that the power is effortlessly and instantly delivered.
As a result, the new BMW 335i can show off its prowess with a 0 to 60 mph
sprint time of just 5.4 seconds,. The automatic version is on par, reaching 60
mph a full 0.2 seconds faster than the outgoing model. Top speed remains the
same, at an electronically governed 130 mph (210 km/h) and 155 mph (250
km/h) with Sport Line.
All this extra performance comes with exceptional fuel economy and low
emission figures. Fuel consumption in the EU test cycle is rated at 7.9 liters per
100 kilometers (29.8 mpg). Fitted with the new eight-speed automatic
transmission, the BMW 335i is even more frugal, with combined fuel
consumption of just 7.2 liters per 100 kilometers (32.6 mpg). The improvement in
emissions for the manual and automatic versions works out at 6 and 16 per cent
respectively. EPA rating will be announced closer to the on-sale date in the
USA.
Sporty 6-speed manual transmission as standard; state-of-the-art eight-
speed automatic optionally available for both engine versions.
The BMW 3 Series owes its characteristic driving experience not just to its high-
torque, fast-revving engines, but also to its transmissions. For performance-
minded drivers the transmission, as the interface where the power from the
engine is relayed to the rear wheels, is pivotal to a dynamic driving experience. It
is just as important for it to offer precise, short-throw shifting as it is to provide
the right ratios. Smooth shifting, low noise and efficient design are further
qualities demanded in the premium segment. For drivers who value a hands-on
approach, the new BMW sports sedan is equipped with a 6-speed manual
transmission as standard, while those who prefer to leave the shifting to the
transmission will find an ideal alternative in the innovative 8-speed automatic.
Finally, customers can also opt for a Sports Automatic version of this
transmission, with steering wheel-mounted paddle shifts as an upgrade with the
Sport Line and M Sport package.
6-speed manual transmission as standard.
The sporty 6-speed manual transmission in the new BMW 3 Series boasts an
easy and precise shifting action and optimal ratio spacing. The lightweight,
compact format and innovative, low-friction design help to further enhance shift
feel and efficiency. The transmission used on the BMW 335i, is equipped with
dry sump lubrication for significantly improved efficiency and shifting quality, due
to reduced drag losses. At the same time, noticeably more comfortable shifting is
achieved by the use of innovative carbon friction linings in the synchromesh
units. The new BMW 328i likewise features an optimized transmission with ratios
precisely matched to the performance characteristics of the new engine. The
optimal ratio spacing makes for powerful sprinting performance and fast mid-
range acceleration, all combined with a reduction in fuel consumption.
Innovative 8-speed automatic transmission: efficient power transmission
and optimal ratios.
The new BMW 3 Series can be equipped with an optional high-performance
8-speed automatic transmission, which can be combined with any of the engines
being presented. The additional ratios allow this state-of-the-art transmission –
which is an option not currently offered by any competitors in the premium
compact sports sedan segment – to combine unprecedented standards of
comfortable shifting, sporty performance and efficiency. With all this going for it,
the automatic transmission is fully in keeping with the overall sporty
temperament of the new BMW 3 Series Sedan.
In terms of size and weight, this 8-speed unit is comparable with the 6-speed
automatic transmission used in the past. A range of innovative technical features
and exceptionally high internal efficiency allow this higher-performance unit, too,
to combine powerful acceleration, strong mid-range sprinting and further reduced
fuel consumption. For performance-minded drivers this transmission also has
lots to offer, particularly since the driver can choose to play a more active role by
changing gear manually, thereby releasing even more of this sporty sedan’s
potential.
With its optimized control technology, the 8-speed transmission boasts extremely
fast shift and reaction times and direct downshift capability. The electronic
transmission controller can also alter the shift characteristics as required, to
cater either for a sportier or for a more relaxed, fuel-saving driving style. Despite
a larger overall spread, eight ratios mean that the spacing between them is
smaller, so that the optimal ratio is available in virtually all situations. The close
ratios deliver turbine-like power combined with smooth and fuel-efficient low-rpm
operation. Altogether, then, as well as providing dynamic acceleration and
smooth shifting, the new 8-speed automatic also allows drivers to maintain a
very economical driving style. This all helps to explain why, when fitted with the
8-speed automatic transmission, the new BMW 3 Series has even lower fuel
consumption than models equipped with the 6-speed manual transmission.
A sports version of the new 8-speed automatic transmission is available as an
option for cars equipped with the Sport Line and M Sport package. This unit
offers even sportier shift characteristics (e.g. faster shift times), and the option of
changing gear manually using the paddle shifts on the steering wheel.
Alternatively, it is also possible to use the electronic Quickshift selector lever on
the center console. The Normal and Sport modes are chosen using the Driving
Dynamics Control switch. This allows the Sports Automatic to deliver both
dynamic driving enjoyment and top-level comfort.
Precision chassis engineering sets new standards:
sporty handling, high agility and increased comfort.
In the sixth model generation, too, dynamism and performance are among the
stand-out features of the BMW sports sedan. These qualities are underpinned by
a precision-engineered chassis with four-wheel independent suspension that
perfectly complements a winning formula: a longitudinally mounted engine, rear-
wheel drive, balanced weight distribution and torsionally stiff body. In the new
BMW 3 Series the engineers have further improved the already outstanding
handling qualities of its predecessor and its excellent agility and directional
stability, while at the same time noticeably improving comfort. To achieve this,
they have made extensive use of extra-lightweight chassis components,
sophisticated and perfectly tailored axle kinematics and a high-precision steering
system. State-of-the-art electronic control systems on the new BMW 3 Series
Sedan help manage the vehicle dynamics and ensure that the combination of
outstanding sporty performance and increased comfort can be enjoyed to the full
and with complete peace of mind.
With friction-reduced wheel bearings and ball joints, aerodynamic improvements
at the rear axle and reduced rolling-resistance tires, the whole chassis plays its
part in reducing fuel consumption and thus emissions.
A wheelbase of 110.6 inches / 2,810 mm (+ 1.96in/50 mm) and a front and rear
track width of 60.3 / 1,543 (+ 1.46 in / 37 mm) and 61.9 / 1,583 millimeters
(+ 1.85 in/ 48 mm) respectively give the new BMW 3 Series Sedan a more road-
hugging stance than its predecessor, while the weight-optimized powertrain and
lightweight body design result in a perfectly balanced 50:50 weight distribution.
Double-pivot front axle with spring struts and anti-roll bar.
The new BMW sports sedan adopts an innovative but proven front axle design
which provides an optimal fusion of driving dynamics and comfort. The
suspension components combine maximum stiffness with minimum weight.
Aluminum torque struts, wishbones and swivel bearings bring a substantial
reduction in unsprung masses. At the same time, the absence of torque steer
makes it easier to gear the kinematics of the double-joint axle to agility and
dynamism.
Advanced axle design further refined:
five-link rear axle improves driving dynamics and comfort.
Incorporating various significant improvements and refinements, the rear axle of
the new BMW 3 Series makes an important contribution to the new model’s
improved driving dynamics and comfort. Its space-saving design is based on the
tried-and-tested five-link design used on the predecessor model, with
elastokinematics which have been specially tailored to the new sports sedan,
featuring long spring travel and precise and confident wheel location in all
situations.
Extra-wide mounts and supports on the wheel carriers for track and camber,
extremely stiff control arms, the stiff axle subframe and thrust arms connecting
the suspension and body provide an excellent basis for the agile and, at the
same time, comfortable overall suspension qualities of the new BMW 3 Series
Sedan. The large mounts and supports at the rear axle not only affect handling,
they are also important for ensuring good acoustic insulation between the
powertrain and suspension, particularly on vehicles with a powerful, high-torque
engine. Thanks to the effective insulation of the powertrain from road excitations,
the new rear axle also provides first-class noise and vibration damping.
The classic BMW 3 Series rear-wheel-drive set-up and a balanced weight
distribution also provide the ideal basis for resolving the conflict between ride
and handling. As a result, the new BMW 3 Series impresses with extremely
sporty handling combined with highest standards of stability and comfort. Last
but not least, the reduced-friction wheel bearings, robust powertrain isolation and
carefully targeted aerodynamics modifications at the rear axle also contribute to
improved driving dynamics and efficiency.
Optional Variable Sports Steering.
Optionally a new variable-ratio steering system can be ordered. Variable Sports
Steering provides different steering gear ratios depending on the turning
situation, so that the new BMW 3 Series responds either more directly or more
softly to the driver’s steering inputs. This reduces the number of steering wheel
rotations required for bigger turns by up to 25 percent and makes for easier,
more convenient parking and turning since less effort is required from the driver.
Also, the handling is sharper in general, for example when very sudden evasive
action is called for. At smaller steering angles between zero and 100 degrees, on
the other hand, the Sedan provides high standards of track-holding and
straightline stability, and offers satisfyingly precise response to steering changes.
The variable-ratio steering is a purely mechanical system based on a variable-
ratio steering rack.
High-performance lightweight brake system.
The dynamic performance of the sports sedan calls for an equally powerful brake
system. The new BMW 328i uses lightweight floating caliper brakes at all
corners with large vented discs while the 335i uses 4-piston fixed calipers at the
front and floating calipers at the rear. The aluminum front fixed calipers bring a
further reduction in unsprung masses. This extremely high-performance system
also features outstanding heat tolerance, excellent wet braking performance,
easy operation and precise control. Together with the large wheels and high-grip
wide tires, it provides the sports sedan with highly effective deceleration.
The brake system is further supported by various state-of-the-art electronic
safety systems, which are integrated into the Dynamic Stability Control (DSC)
system for improved driving dynamics and safety. The DSC system incorporates
the following functions: Anti-lock Braking System (ABS), Automatic Stability
Control (ASC), Dynamic Traction Control (DTC), Dynamic Brake Control (DBC)
and Cornering Brake Control (CBC), along with start-off assist, brake drying and
an electronic limited slip function for the rear differential, which can be activated
using the “DSC Off” button.
Driving Dynamics Control switch with ECO PRO Mode:
extra-sporty, more relaxed or more fuel-efficient driving modes – at the
press of a button.
The new BMW 3 Series offers impressive driving dynamics combined with new
standards of comfort in the segment. This is a result of superbly tuned
suspension which achieves an astonishing balance between dynamics and
comfort. On top of this, drivers are also able to vary the overall character of the
sedan depending on the driving situation or to suit their personal preferences. As
well as sportier or more comfortable drive settings, they can also opt for extra
fuel efficiency. The different modes are selected using the new Driving Dynamics
Control function including ECO PRO mode, which is standard on all 3 Series
models.
Using the Driving Dynamics Control switch, the driver is able to customize
accelerator response characteristics, engine response, the power steering
characteristics and the Dynamic Stability Control (DSC) thresholds. The
Servotronic function, the automatic transmission and Dynamic Damper Control
are integrated into the system too. Using the simple-to-operate rocker switch on
the center console, drivers can choose between ECO PRO, COMFORT, SPORT
and SPORT+ modes. Each of these predefined setups activates different
settings for the relevant powertrain and suspension components.
In SPORT Mode, for example, throttle response is very sharp and the steering
becomes even more direct. On vehicles with automatic transmission, the shift
points are altered to provide a significantly sportier drive.
A further button allows the driver to change the DSC settings. Selecting Dynamic
Traction Control (DTC) mode, for example, makes it much easier to start off on
loose surfaces or in deep snow. In this mode as well as in SPORT+ mode, the
Dynamic Stability Control thresholds are raised and Dynamic Traction Control
(DTC) is activated. It is also possible to shut off DSC altogether. The electronic
limited-slip function for the rear differential can then provide extra-sporty
acceleration out of corners or hairpins.
The new ECO PRO Mode, meanwhile, supports an extra-efficient and economy-
conscious driving style. It does this by changing the accelerator mapping so that
the same pedal travel delivers less power than in the standard mode. Also in this
mode, the automatic transmission control strategy is modified so as to upshift
sooner and to delay downshifts, while intelligent energy and climate
management reduces the mechanical power consumption and also the
consumption of electrical systems such as heated mirrors and seats. But the
biggest potential for improving fuel economy comes from the driver’s own
personal driving habits. Special displays in the instrument cluster let the driver
know by how much the driving range is being extended, show fuel consumption
history, or, with reference to the specific driving situation, provide tips and
incentives on how to develop a more economy-conscious driving style. ECO
PRO mode allows average fuel consumption to be reduced by up to 20%, with a
corresponding increase in driving range.
Dynamic options: M Sport package, Adaptive M Sport suspension, sports automatic
transmission and BMW 3 Series xDrive.
For out-and-out enthusiasts, further features are available to enhance the
dynamic driving qualities of the new BMW 3 Series and give them a distinctive
visual dimension as well. The M Sport package, which will become available
after launch, is designed for this very purpose and has been developed
specifically for this model series. It includes the lowered M Sport suspension,
featuring a 10 millimeter (0.4 in.) drop in ride height, firmer suspension and
damping, and larger anti-roll bars. Also featured are 18 or 19-inch M alloy
wheels. The package is completed by an M aerodynamics package featuring
special body parts, and by chrome tailpipes, exclusive exterior paintwork and
interior trim to match. An Adaptive M Sport suspension with electronically
controlled damping is also optionally available for the new BMW 3 Series. Based
on incoming information about body and wheel acceleration, lateral and
longitudinal acceleration, vehicle speed and steering wheel position, an
electronic control unit adapts the damper mapping to the road surface and
driving situation. At the same time the driver can use the Driving Dynamics
Control switch to vary the basic suspension characteristics between more
comfortable or sportier settings. An 8-speed sports automatic transmission with
faster shift times and sporty steering wheel-mounted paddle shifts is also
available as an option.
The new BMW 3 Series will soon provide even more variety and become even
more attractive with the introduction of BMW xDrive intelligent all-wheel drive. In
addition to the typical benefits of all-wheel drive, the electronically controlled
BMW xDrive system – which can fully vary the driver power split between the
front and rear wheels with split-second speed – ensures top-class traction, safety
and handling, and optimal power management whatever the weather and road
conditions. The system has been recalibrated for greater agility and precision,
with benefits also for cornering. In this new version it offers an ideal combination
of dynamism and comfort, and is the ideal basis for maximum driving enjoyment.
The BMW 335i xDrive and BMW 328i xDrive, all-wheel-drive models will go on
sale in summer 2012.
BMW EfficientDynamics: More power, less fuel consumption.
With high-performance engines, superior suspension technology and an
extremely torsion-resistant body, the new BMW 3 Series is building on its
position as the sportiest sedan in its segment. It is also advancing even further
on the comfort front. Agility and dynamic performance continue to be the sports
sedan’s stand-out features, and are key to its high standards of driving
enjoyment. To cap this off, the 3 Series also boasts an exceptionally good
balance between performance and fuel consumption. This reassuring knowledge
is a further incentive for drivers to make full use of the dynamic potential of the
new BMW 3 Series.
To a large extent, these typical BMW qualities are due to the BMW
EfficientDynamics strategy that is extensively used on the new sports sedan.
New, more fuel-efficient engines, extra-efficient transmissions, on-demand
control of ancillary units, intelligent lightweight design, Auto Start-Stop function,
and low drag aerodynamics including “Air Curtain” and underside fairing all help
to consolidate the leadership position of the new BMW 3 Series on fuel
consumption and emissions.
Auto Start-Stop, Brake Energy Regeneration, ECO PRO Mode.
The new BMW 3 Series Sedan is equipped with an Auto Start-Stop function,
which automatically switches off the engine during short stops at traffic lights or
in stationary traffic, so as not to waste fuel. For the first time, and uniquely in this
class, this system can be combined with the new 8-speed automatic
transmission as well as the manual gearbox. The new BMW 3 Series is also
equipped with BMW’s now familiar Brake Energy Regeneration system. With
Brake Energy Regeneration, power for the vehicle electrical system is generated
only during braking and overrun. When the engine is under load, the alternator
can often be disengaged. This not only means that electricity can be generated
with little or no effect on fuel consumption, it also grants the sports sedan livelier
acceleration. Finally, the new Driving Experience Control switch gives drivers the
option of selecting ECO PRO Mode which, by modifying the powertrain
management and re-programming the heating and air conditioning, the heated
seats and the exterior mirrors to operate at optimum efficiency, reduces fuel
consumption by as much as 20%.
On-demand control of ancillary units saves energy.
Intelligent energy management in the new BMW 3 Series is further enhanced by
the ancillary units, which consume significantly less energy compared with
conventional systems. Examples include the on-demand coolant pump, the
electronically controlled oil pump and the electromechanical steering system,
which only consumes electric power when steering assistance is actually
required. The special air conditioning compressor featured on many of the sports
sedan models works on the same principle. As soon as the driver switches the
air conditioning off, the belt drive to the compressor is disconnected by a
magnetic clutch, to minimize power drain.
Intelligent lightweight design brings further reduction in fuel consumption.
Use of lightweight materials has played a significant role in reducing vehicle
weight and in delivering high passenger cell safety standards, combined with a
significant increase in strength. At the same time, these measures also help to
ensure superior driving dynamics. Intelligent lightweight design is integrated into
all areas of BMW vehicle development work and into all components, from the
body and engine to the suspension. Materials used include high and ultra-high
tensile steels, a hot-stamped B-pillar, plastics and state-of the-art composites.
Increased use of aluminum components in the engine and suspension systems
has also further reduced the weight of the relevant assemblies.
Aerodynamic optimization of underside paneling.
It is common knowledge that fuel consumption can also be cut by reducing
aerodynamic drag. As the excellent drag coefficient (cd = 0.26) would suggest,
the aerodynamics of the new BMW 3 Series have been intensively honed in
BMW’s state-of-the-art full scale rolling road wind tunnel. The optimized
aerodynamics also have benefits for noise reduction and roadholding. In
particular, streamlined design of the underside plays a big part in minimizing lift
forces. The aerodynamically optimized underside with extended streamlined
panels at the sides, under the engine compartment shield and at the front part of
the exhaust tunnel provides unprecedented standards of sealing. Additional
aerodynamic covers, which create a diffuser effect at the rear axle, further
reduce drag and lift forces, while at the same time improving stone chip
protection. Also, the front aprons are designed to incorporate the “air curtain”
effect which reduces turbulence in the wheel arch area – again reducing drag.
This system was first introduced on the 1 Series M Coupe in 2011. The
aerodynamically designed wheel arches, and the air deflectors in front of them,
likewise help to reduce fuel consumption.
Dynamic, efficient and innovative: The new BMW ActiveHybrid 3.
In autumn 2012 a sensational new model will join the BMW 3 Series. In the new
ActiveHybrid 3 – the world’s first hybrid at the premium end of the sports sedan
class – the innovative BMW ActiveHybrid powertrain technology and the sporty
personality of the BMW 3 Series meet and merge with highly dynamic and
efficient results. The combination of the 6-cylinder engine and electric drive
produce unrivaled driving enjoyment, combined with even better fuel
consumption and emissions figures, and further intensify the sporty, yet fuel-
efficient driving experience that lies at the heart of the new BMW 3 Series. The
gains in both performance and efficiency are a textbook example of the
BMW EfficientDynamics development strategy in action. Following the
BMW ActiveHybrid 7, BMW ActiveHybrid X6 and BMW ActiveHybrid 5, the new
BMW ActiveHybrid 3 is the fourth production model in which a model-specific
intelligent combination of internal combustion engine and electric drive provides
extra performance while at the same time significantly slashing fuel consumption
and emissions. In the BMW ActiveHybrid 3, ActiveHybrid technology has for the
first time been integrated into the vehicle architecture right from the start.
Amongst other things, this meant that a lot of space was saved.
The powertrain of the BMW ActiveHybrid 3 is closely tailored to the sporty
personality of the new BMW 3 Series. It features the 225 kW/ 300 hp inline 6-
cylinder engine with BMW TwinPower Turbo technology (N55) and a hybrid-
specific eight-speed automatic transmission with an integrated electric motor
which for limited periods can increase power by up to 40 kW/ 55 hp. Maximum
combined output is 250 kW/ 335 hp, with a maximum combined torque of 330 lb-
ft. This high-powered, high-performance combination nevertheless returns
extremely low fuel consumption. Average consumption in the EU test cycle is
less than 6.4 liters per 100 kilometers (36.7 mpg). That means the ActiveHybrid
technology in the BMW ActiveHybrid 3 offers fuel savings of more than 12.5
percent compared with equally powerful conventionally driven BMW sports
sedans.
The electric motor supplies the 6-cylinder engine with supplementary driving
power and can provide a boost function when extra-dynamic performance is
required. This adds a further edge to the driving experience in the BMW
ActiveHybrid 3. BMW ActiveHybrid technology also allows the vehicle to run
solely on electric power. In this zero-emission, virtually soundless driving mode,
the vehicle can cover a distance of between 2 to 2.5 miles (around three to four
kilometers). Top speeds in all-electric mode range from 37 mph (60 km/h) under
load to 100 mph (160 km/h) on overrun (coasting). When the driver applies more
throttle, the internal combustion engine is engaged automatically, then
disengaged on overrun. During overrun and braking, the electric motor acts as a
generator, converting kinetic energy into electrical energy, which is used to
charge the battery. This is the same principle as the Brake Energy Regeneration
function on the regular models, although on the BMW ActiveHybrid 3 the amount
of energy recuperated by the electric motor is many times greater.
Efficient and seamless integration between the internal combustion engine and
electric motor is ensured by the central power electronics, which provide
intelligent, proactive energy management to further improve overall system
efficiency. In terms of utility and interior adaptability, the BMW ActiveHybrid 3
shows no significant differences from the other models in the series, since its
high-voltage battery is integrated under the floor of the trunk. With trunk space of
390 liters (DIN) and unrestricted through-loading functionality, there are no
concessions on the car’s high standards of comfort and convenience. Drivability
too is on a par with that of a BMW 335i.
BMW ConnectedDrive: Intelligent integration provides greater comfort,
safety and infotainment.
The BMW ConnectedDrive range of technology includes a portfolio of innovative
functions – unique worldwide – which serve to ensure maximum comfort,
infotainment and safety. BMW ConnectedDrive uses the intelligent link-up of the
driver, car and outside world to provide useful information for the situation at
hand. The technical pre-eminence and progressive character of the new BMW 3
Series is underpinned by an unmatched combination of driver assistance
systems and mobility systems from BMW ConnectedDrive.
Among the most prominent technologies developed under the banner of
BMW ConnectedDrive are the comfort-enhancing systems BMW Parking
Assistant and Surround View. They are joined in the new BMW 3 Series Sedan
by features which further increase levels of passenger comfort – such as office
services, calendar and Facebook as examples.
High-functionality interface technology providing a prime example of state-of-the-
art infotainment capability enables the driver and passengers to make extensive
use of external mobile phones and music players inside the new BMW 3 Series
Sedan. With new Bluetooth office functions from BMW ConnectedDrive, internet-
based services such as weather, news etc., as well as calendar entries and text-
based messages (SMS and e-mail), can be viewed in the Control Display of the
iDrive operating system and read out via the Text to Speech function. In addition,
passengers can access their personal music library on their smartphone or
music player inside the car. Their playlists, stored song titles and relevant album
cover artwork are then displayed on the on-board monitor. The BMW Connected
Drive app allows full in-car use of web radio and calendar functions in
combination with the Apple iPhone. In addition to web radio music streaming
services such as Pandora and MOG can be accessed safely and conveniently
through the iDrive controller and screen.
The constantly expanding number of driver assistance systems from
BMW ConnectedDrive provide added safety and assurance on the road. In a
new development in this premium class, the new BMW 3 Series Sedan will be
available with the new-generation full-color Head-Up Display. Key driving
information is projected – in sharp resolution – onto the windshield so it appears
directly in the driver’s field of view. Safety is given a further boost by the
availability of the Active Blind Spot Detection System and Lane Departure
Warning System including Collision Warning. This technology warns the driver of
a possible collision during a lane change maneuver or if the car strays
unintentionally out of its lane. Meanwhile, the Advanced Collision Notification
function help occupants to limit the consequences of an crash, should the worst
come to the worst.
Head-Up Display with full-color capability.
The new-generation Head-Up Display now delivers even greater display quality,
functionality and flexibility. The symbols projected onto the windshield are
displayed in sharp resolution in the driver’s direct field of vision. All of which
allows drivers to view all of the information in this ergonomically excellent
position without having to divert their gaze from the road ahead. A full range of
colors are used to reproduce common road sign symbols as accurately as
possible through the display graphics. Depending on vehicle specification, the
car’s speed, cruise control setting, navigation instructions and alerts from the
Collision Warning and Lane Departure Warning systems will be displayed. Even
direction indicators and Check/Control messages can now be displayed, as well
as a wide range of information selected personally by the driver. The intensity of
the projections adapts automatically to the light conditions, and therefore follows
the illumination of the cockpit dials. Added to which, the precise positioning of
the projections on the windshield can be adjusted easily using the iDrive
Controller. The variety of driver assistance systems available for the BMW 3
Series Sedan increases the amount of information that can be shown in the
Head-Up Display to a whole new level.
Active Blind Spot Detection System monitors vehicles following behind.
Inattentiveness or misjudgment of the distance and speed of a vehicle
approaching from behind can lead the driver into a critical situation when
changing lanes. The optional Active Blind Spot Detection System warns BMW 3
Series Sedan drivers of the potential danger of such an overtaking maneuver.
The system uses a pair of rear-mounted radar sensors to monitor traffic in the
adjacent lanes, from the blind spot to a distance of approximately 60 meters (200
ft.) behind the car. This information, indicated to the driver before he actually
changes lanes, allows him to prepare for a lane change maneuver with
confidence and to avoid critical situations from the outset. If other road users are
approaching the car in an adjacent lane or moving through the driver’s blind spot
behind and to the side of the car, a yellow triangle symbol in the housing of the
driver’s side exterior mirror gives a discreet warning of possible danger. If the
driver then still goes ahead and activates the direction indicator, announcing an
intention to pull in or out, the LED symbol starts to flash. A further warning is
provided in the form of a discreet but unmistakable vibration of the steering
wheel rim.
Camera monitoring: Lane Departure Warning System and Collision
Warning.
The Lane Departure Warning System available for the new BMW 3 Series
Sedan is activated at speeds above 70 km/h (43 mph) and warns the driver if he
unintentionally strays out of his lane. The system comprises a windshield-
mounted camera in the rear-view mirror area, a data comparison unit and a
signal generator which – as with the Active Blind Spot Detection System –
causes the steering wheel to vibrate. The Lane Departure Warning System is
speed-sensitive. At high speeds, the system reacts at a suitably early stage if the
car is getting close to the lane markings. The camera tracks the lane markings
on at least one side of the car, and the control unit uses image processing to
calculate the position of the car in relation to the markings. The camera focuses
some 50 meters (164 ft.) ahead of the car and is also active through corners and
on narrow roads. Indeed, the system even works in the dark as soon as the
headlights have been switched on. The driver can therefore count on its services
in a wide range of everyday driving scenarios. The system does not give a
warning if the driver has signaled an intention to change lanes or turn off by
switching on the direction indicator. BMW ConnectedDrive uses a high-tech
multifunctional camera, mounted on the rear-view mirror, to initiate a number of
different driver assistance systems. With the new BMW 3 Series Sedan, BMW
will become the first premium manufacturer to use such a camera for monitoring
traffic on the road ahead. The image processing system continuously scans the
scene on the road and gives an audible warning if it identifies a potential collision
risk. If the driver draws too close to the vehicle in front, the system produces an
acute audible warning and a visual signal appears in the instrument cluster or
the optional Head-Up Display, if specified. At speeds upwards of 50 km/h (30
mph), the brake system is primed and the activation threshold of the hydraulic
Brake Assist system is lowered. These measures, which are activated
simultaneously with the visual and audible warnings, are designed to help the
driver react effectively in an emergency. There is no automatic braking
intervention. The sensitivity of the automatic Collision Warning system can be
individually configured by the driver through several stages.
If the worst comes to the worst: BMW Assist enhanced Automatic Collision
Notification with automatic vehicle location.
In the event of an accident in the new BMW 3 Series, the enhanced Automatic
Collision Notification system from BMW ConnectedDrive allows the emergency
services to receive detailed information on the type of collision and the likelihood
of trauma level injuries before arriving at the scene of the accident. That allows
first responders to prepare the appropriate medical care in advance for those
involved in the crash. The precise position of the car and vehicle type are
specified, and all the data gathered by sensors in the car is forwarded. The
information provides indications as to the nature and severity of the collision,
while the deployment of the car’s restraint systems gives the emergency
services an idea of the number of injured people and allows frontal, rear, side or
multiple collisions to be identified and differentiated. This is possible thanks to an
advanced algorithm developed in partnership with the William Lehmann Trauma
Center in Miami, Florida that used transmitted vehicle data to estimate the
likelihood of severe injuries as a result of a crash. As well as automatic
activation, the system also allows the driver or front passenger to trigger the
Emergency Call manually and to be connected with the BMW call center without
delay.
Intelligent use of advanced light technology.
The optional High-Beam Assistant for the new BMW 3 Series Sedan provides
enhanced safety at night. The system automatically switches high beams on and
off, as conditions require, ensuring that the driver always has optimal visibility
without having to switch manually between high and low beam. Images recorded
by the camera integrated into the rear-view mirror allow the system to identify
vehicles travelling up to around 400 meters (approx. ¼ mile) in front. Oncoming
traffic is picked up when it is still around 1,000 meters (just under
¾ mile) away, and the system also switches to low beam if ambient lighting is
bright enough.
The optional Adaptive Xenon headlights provide illumination follows the curves
of the road, turn with the steering angle and the speed of the car. The cornering
light function integrated into the fog lights is triggered when the driver switches
on the indicator and turns the steering wheel (at up to 65 km/h /40 mph). Every
time the driver turns, an additional beam of light provides significantly improved
visibility in the area immediately around the car.
Rear view camera and Surround View deliver a perfect overview.
A rear view camera is also available for the new BMW 3 Series Sedan as an
extension of the Park Distance Control (PDC) system. PDC uses sensors in the
bumpers to detect the distance to obstacles in front of and behind the car. The
camera is located in a protected position in the license plate recess of the trunk
lid and sends images with optimized color and perspective to the cockpit
monitor. Interactive lane markings signal the room available for the parking
maneuver and the smallest possible turning circle.
Making its debut in the BMW 3 Series Sedan, the Top View system provides an
even more extensive overview of the car. This system complements the rear
view camera and PDC sensors, and works using two cameras in the exterior
mirrors. The data collected on the car and its surrounding area is processed by a
central computer, which generates an overall image. This is then displayed on
the on-board monitor, presenting a bird’s-eye view of the car and the area
around it, and enabling the driver to carry out precise maneuvers in tight spaces.
If the car is moving at under 20 km/h (12 mph), the driver can – at the touch of a
button – also choose to activate only the Side View function of Top View. Side
View uses two cameras integrated in the sides of the front bumper to monitor
traffic crossing in front of the vehicle. These images are also relayed to the
cockpit, where they not only act as a maneuvering aid but, above all, give the
driver an early idea of what is happening on the road to the left and right of the
car when pulling out from narrow and concealed exits or junctions.
BMW Parking Assistant takes charge of maneuvering into parking spaces.
The BMW Parking Assistant is another comfort-enhancing driver assistance
system from BMW ConnectedDrive to be included in the new BMW 3 Series
Sedan. The new system helps the driver to maneuver safely and comfortably
into parking spaces positioned parallel to the direction of travel. BMW Parking
Assistant uses ultrasound sensors integrated into the side indicator surrounds to
help the driver search for suitable parking spaces. With the car traveling at no
more than 36 km/h (22 mph), these sensors permanently measure the length
and breadth of parking spaces at the edge of the road and on roadside verges.
BMW Parking Assistant searches for spaces at least 1.20 meters (around 4 ft.)
longer than the car itself. With the system activated, the driver is alerted to
suitable spaces as he passes them. When the system is switched off, this
measuring process takes place in the background; only when the driver draws to
a halt and engages reverse gear is the parking space flagged up on the on-
board monitor using a suitable symbol. In both cases, drivers can confirm they
want to use BMW Parking Assistant with a push of the iDrive Controller. During
the parking process all they have to do is operate the accelerator and brake
pedal and keep an eye on the area around the car; the Parking Assistant takes
care of the steering wheel movements required to carry out a precise reverse
parking maneuver. Drivers are given instructions to guide them through the
parking process. Audible and visual alerts from PDC, the rear view camera or
the newly introduced Surround View system help to maintain the required
distance to other vehicles or obstacles in the chosen parking space.
Innovative trunk access makes life a little easier.
BMW ConnectedDrive has come up with another new and intelligent solution
that makes BMW cars even easier to use. The hands-free trunk lid opening
function – available for the new BMW 3 Series Sedan in conjunction with
Comfort Access – is a first in the premium class. Standing behind the car,
customers can prompt the trunk to open with just a short movement of their foot
under the center of the rear bumper, i.e. without using their hands. The trunk
then automatically unlocks and swings open by spring force. The vehicle is fitted
with sensors placed at different heights in the rear bumper trim, which are able to
identify a person standing behind the vehicle. The sensors can identify the foot
“command” by monitoring the area of the leg between the shin and the tip of the
foot. They then send a signal containing special algorithms to the on-board
computer. Access is only authorized, however, if the system simultaneously
identifies the Comfort Access control unit (the key), which the person must be
carrying with them. The trunk lid is then unlocked and raised automatically,
without hand contact. Key authorization provides the safeguard ensuring correct
operation at all times.
Body and safety: The safest BMW 3 Series yet.
The new BMW 3 Series offers its passengers exceptional active and passive
safety. Judicious selection of materials, a high-strength structure and an
intelligent lightweight design concept allow the body to meet the most exacting
standards, and it teams up with highly efficient restraint systems to provide
maximum occupant protection. At the same time, the lightweight construction of
the new BMW 3 Series makes a significant contribution to the efficiency and
agility of the new sports sedan. In addition, an extensive package of active safety
components help the driver to avoid accidents or, if a collision is unavoidable, to
minimize its consequences. The same goes for the optimized pedestrian
protection systems. All in all, the flawlessly assembled overall concept of the
new BMW 3 Series makes it an incredibly impressive proposition – not least in
terms of safety.
High-strength body structure with extremely stiff passenger cell.
The body of the new BMW 3 Series Sedan meets the highest standards across
the board. Large and extremely durable supporting structures and the intelligent
use of high and ultra-high-tensile multi-phase steels maximize the strength of the
safety passenger cell, while keeping weight low. Precisely calculated load paths
ensure that impact energy is spread around the passenger cell to other areas of
the body such as the floor structure, side members, front bulkhead and roof, and
absorbed by defined deformation zones of the front and rear. In the event of a
side-on collision, reinforced structures in the B-pillar and sills, high-strength side
impact members in the doors and sturdy seat cross-members protect the
occupants from injury. With its strengthened pillars and roof members, the
passenger cell also provides a secure survival area for the occupants if the car
rolls over. The body of the new BMW 3 Series Sedan is over 10% more rigid
than its predecessor – good news for drivers who like to see vibrations
suppressed and steering precision nurtured.
Individual protection at every seat.
The exemplary crash responses of the new BMW 3 Series Sedan body also
provide the best possible basis for the optimum design and set-up of the car’s
restraint systems. The sports sedan is equipped as standard with front and side
airbags for the driver and front passenger, plus head airbags for both rows of
seats. Responding to the nature and severity of the impact, the integrated safety
electronics ensure that only those airbags that are able to provide effective
protection are deployed at the optimum time. Those airbags that are not required
remain unused – and therefore ready to spring into action should there be a
second collision. All seats are fitted with three-point inertia-reel seat belts, and
the driver and front passenger also have belt latch tensioners and belt force
limiters. Also part of standard specification are ISOFIX child seat attachment
points for the rear seats.
Improved pedestrian protection.
The front of the new BMW 3 Series features various pedestrian protection
systems. An impact absorber is located between the bumper supports and
bumper trim, reducing leg injuries, while the hood is built to include deformation
elements, which absorb impact energy. These optimized measures help to
reduce the risk of injury and mitigate the consequences of an accident.
A host of active safety systems reduce the risk of accidents.
A selection of electronic assistance systems make an active contribution to
driving safety in the new BMW 3 Series, helping drivers to avoid collisions in the
first place. The functions of the main assistance systems have already been
described in the “BMW ConnectedDrive” chapter, but the stand-out features
include the, daytime running lights, Adaptive Headlights with variable light
distribution and anti-dazzle High-Beam Assistant, dynamic brake lights, a rear
view camera, the Lane Departure Warning System including Collision Warning,
the Lane Change Warning System and Speed Limit Info.
The all-new BMW 3 Series Sedan will arrive at US BMW centers in February 2012 as a
2012 model. Images and video can be downloaded from www.bmwusanews.com.
