Release) Highlights include styling updates inside & out,
new technology and the introduction of BMW Advanced Diesel with
Woodcliff Lake, NJ -
July 16 2008... The 2009 3 Series Sedan and Sport Wagon is poised to
maintain its market leadership with updated exterior and interior
styling, new technologies, enhanced ergonomics and, as previously
announced, the U.S. introduction of BMW Advanced Diesel with
BluePerformance in the form of the 335d Sedan.
The new BMW 3
Series Sedans and Sports Wagons, already and always leaders in
their class, widen their lead in driving dynamics, premium
quality and innovative technology.
These vehicles combine unique BMW elegance with a driving
experience that's widely imitated, yet really inimitable.
A brand-new twin-turbo diesel engine, thoroughly BMW in its
performance and character, powers the new 335d Sedan and expands
the scope of BMW EfficientDynamics.
Subtle freshening of exterior design features a new front end,
more dynamic profile, and wider appearance at the rear.
Headlights and taillights are new, yet present a typically BMW
look, innovative lighting technology and 3-dimensional effects.
Refinement of interior design and amenities includes new
colors and materials. Overall design of interior reflects and
complements the distinctive exterior design. Among functional
updates are ergonomically enhanced placement of power-window
controls for the driver and new, expanded storage possibilities.
New generation of BMW iDrive, available in 3 Series in
combination with optional Navigation system: ergonomically
optimized iDrive controller with function selection and
activation via turn, push and tilt motions; new direct-select
keys; more Programmable Memory Keys than before. The newly
enhanced Navigation system offers greater functionality.
BMW Advanced Diesel with BluePerformance: all-new inline
6-cylinder twin-turbo diesel engine with an impressive array of
new features for high performance, high fuel efficiency and
clean exhaust. To achieve these targets, this aluminum
powerplant applies common-rail, high-pressure direct fuel
injection with piezo injectors; 2-stage turbocharging; exhaust
particulates filter; and Selective Catalytic Reduction exhaust
after-treatment to reduce NOx. Displacing 3.0 liters, this truly
advanced engine enables BMW to introduce diesel power in all 50
U.S. states; it produces 265 hp and an amazing peak torque of
425 lb-ft.; 0-60 mph in 6.0 sec. with 6-speed automatic
transmission. EPA mileage ratings have not been finalized, but
are expected to set new "mile"-stones in the simultaneous
achievement of performance with fuel economy.
Continuation of two other trailblazing BMW inline 6-cylinder
performance concepts in the other 3 Series models: the 3.0-liter
naturally aspirated unit in 328i models with weight-saving
magnesium/aluminum composite construction and Valvetronic
induction technology for 230 hp; and the 3.0-liter
twin-turbocharged engine of 335i models with its direct fuel
injection (piezo injectors here, too) and large-volume dual
exhaust system. This unit delivers 300 hp, and a peak torque
that is remarkable not only for its quantity (300 lb-ft.) but
for the range over which it's at the driver's disposal (1400 to
5000 rpm). Both of these gasoline engines have been acclaimed
widely for their respective qualities: for the 328i unit, silky
and strong performance with remarkable fuel economy; for the
335i, dramatically sporty performance with fuel economy that's
notable in view of the power.
BMW's acclaimed xDrive all-wheel drive is featured in the
newly named 328i and 335i xDrive Sedans and 328i xDrive Sports
Wagon. This intelligently engineered AWD system steplessly
varies the torque split between front and rear wheels to enhance
not only traction, but also agility and stability on grippy, as
well as slippery road surfaces.
Comprehensive safety concept with extremely rigid body
structure; carefully defined "force paths" that lead and
distribute collision forces optimally through the structure;
targeted application of high-strength steels and deformation
elements; six airbags including front side-impact and front/rear
head protection; new Active front head restraints.
The 2009 models are: 328i Sedan and Sports Wagon; 328i xDrive
Sedan and Sports Wagon; 335i, 335i xDrive and 335d Sedans. The 3
Series also encompasses Coupes and retractable-hardtop
Convertibles; these continue with less extensive updates for
Segment original remains segment
The BMW 3 Series is an
internationally recognized symbol of the intelligently sporty motor
vehicle. It is also the best-selling premium vehicle in the world.
Updates for the 2009 Sedan and Sports Wagon models include -
Refinement of interior design and functions
New and/or revised options
A new generation of the iDrive control and display system
Expansion of ConnectedDrive functions
An all-new turbodiesel engine in a new model - the 335d Sedan.
- and still not successfully challenged in other quarters - are the
Series' essential attributes of rear-(or all-)wheel drive,
harmonious front/rear weight balance, outstandingly precise steering
and skillfully engineered suspension
all of which conspire to
produce the uniquely satisfying driving experience that is
And, more than ever, this inimitable driving experience in
combination with growing attention to fuel efficiency and
environmental consciousness. Thanks to the various facets of BMW
EfficientDynamics - especially via the new turbodiesel-powered 335d
Sedan - the BMW experience is more satisfying than ever before.
New design accents for greater
sportiness and elegance.
The new Sedans are
distinguished by a freshened design at the front, in profile and in
the rear view; the new Sports Wagons receive the same front-end and
profile updates, as well as most elements of the rearview changes.
At the front, width is more strongly accented, though actual width
is unchanged. BMW's traditional 4-headlight look is emphasized by
the lamps' setting in new chromed "tubes;" the more recently
traditional luminous rings around the headlights newly serve as
Daytime Running Lamps on vehicles with Xenon Adaptive lights
(optional 328i models, standard 335i models). The turn-signal lamps
get a new, vertically layered look; in combination with the Xenon
headlights these are in LED technology.
In profile, the side sills/rocker panels set a stronger lower
accent; newly shaped side mirrors not only have crisp new contours,
but also provide an enlarged visual field for the driver.
At the rear, the bumper, taillights and (on the Sedans) trunklid are
all newly shaped for a stronger emphasis on the 3's sporty
character. The taillights' typical L-shape is now more in evidence,
and new LED lighting sources illuminate the taillights and
turn-signal lamps. And an actual increase in rear track adds new
emphasis to these vehicles' wide stance in rear and Ύ views.
Interior: high-quality materials,
enhanced ergonomics and a new-generation iDrive system.
Subtle updates to
materials and surface textures make the 3 Series interior even more
attractive; refinement of interior design and amenities include
enhanced placement of power-window controls for driver and new,
expanded storage possibilities.
In the 3 Series, BMW's iDrive control and display system is included
in the Navigation option. As in the new 7 Series (where iDrive and
Navigation are standard), a 2nd generation of iDrive sets new
standards for ergonomics, efficiency and logical functionality with
its new, higher-definition, 8.8-in. Control Display. More uniformly
structured menus, and an optimized control strategy for the display
and console-mounted controller are also signature new features.
Other new details include keys for direct selection of the Radio,
CD, Navigation and Telecommunications menus, grouped conveniently
next to the controller. Visual assists and consistent hierarchies in
the display simplify choices within the individual menus. In the
Navigation section, users will experience a new and superior level
of brilliance, detail and variability of map displays. A "map
preview" function facilitates selection of the navigation
destination from a list; in a new operational logic, letters of the
alphabet and numerals are arranged in circular form for more
intuitive input of addresses and phone numbers.
Hard drive for audio and
Navigation data storage.
Newly included in the
Navigation option is a hard drive for storage of Navigation data
(such as destinations) and audio material (such as music). The large
capacity hard drive means quick access, and allows transfer of
material from a CD, MP3 player or a USB stick to the hard drive,
which can hold up to 8-GB of music.
BMW Assist: expanded capabilities
As a dynamically
evolving array of valuable functions, the new 3 incorporates BMW
Assist and TeleService functions (both included in the BMW Assist
option). Automatic emergency calling, a long-standing standard
feature of the BMW Assist telematics scheme, is meaningfully
enhanced in the new 3: In the event of a collision of a certain
severity, the system transmits to the BMW Call Center the vehicle's
location and specifications, as well as data from several onboard
sensors that define the type of collision and probability of
occupant injury. At the same time, the Call Center attempts to
establish a voice connection with the vehicle occupants and deploys
emergency services as appropriate.
BMW Advanced Diesel with
BluePerformance: high-performance, high-efficiency
twin-turbo diesel engine in the 335d Sedan.
As an important element
of BMW EfficientDynamics, the new 335d Sedan represents a
significant step forward in combining high performance with high
fuel efficiency. The 3.0-liter, twin-turbocharged inline 6-cylinder
diesel engine powering the 335d - its predecessor has been widely
acclaimed in Europe - is completely new to the U.S. also new is its
BMW BluePerformance emission-control technology.
Among the turbodiesel engine's advanced attributes are aluminum
construction, high-pressure direct fuel injection with piezo
injectors (also a feature of BMW's twin-turbo gasoline engines), and
a turbocharging system that employs both a small and larger
turbocharger for optimum response at low and higher speeds.
As a worldwide advance also being newly introduced in Europe, BMW
BluePerformance controls emissions to a strict level that enables
the 335d to be sold in all 50 U.S. states. Specific features of this
system include an exhaust particulates filter and a Selective
Catalytic Reduction exhaust after-treatment system.
Given the stringent emission control and fuel economy that will
truly raise eyebrows (official EPA mileage ratings are not yet
available), one might expect performance to suffer. On the contrary:
this new power concept achieves not only abundant power (265 hp,
0-60 mph in 6.0 seconds with the standard 6-speed automatic
transmission), but immense torque (425 lb-ft.) that gives the 335d
all-speed acceleration response that simply has to be experienced to
be believed. And - a quality of smoothness and sound that fully
lives up to the BMW reputation for sonorous power.
Gasoline-powered 3 Series models:
continuing the BMW tradition
of smoothness, great sound and outstanding fuel efficiency.
All other 3 Series
models continue with their (also) acclaimed 3.0-liter inline
6-cylinder gasoline engines.
The 328i models are powered by a naturally aspirated (i.e.,
non-turbo) engine that features advanced, weight-saving
magnesium/aluminum construction - still unique among the world's
automobiles. Its Valvetronic system enhances efficiency by employing
variable valve lift, rather than a throttle, to regulate engine
power. This engine produces 230 hp, 200 lb-ft. of torque, and EPA
highway mileage ratings as high as 28 mpg (depending on model and
transmission) in 2008. It is a sterling example of BMW's
long-standing tradition of the smooth, sonically delightful "inline
six" that delivers excellent performance.
For those who desire more than merely excellent performance, the
335i models are powered by a completely distinct 3.0-liter six,
boosted by twin turbochargers and fed with fuel by High Precision
direct fuel injection. This unique and highly advanced unit delivers
300 hp and 300 lb-ft. of torque, 0-60-mph times as quick as 5.4
sec., and EPA highway mileage ratings up to 26 mpg. If the 328i
engine has been enthusiastically acclaimed, the 335i unit has
garnered downright deliriously praise, particularly by the
automotive enthusiast media.
Intelligent all-wheel drive in the
3 Series: the xDrive models.
Continuing for '09 are
the two Sedan models and one Sports Wagon model with BMW's truly
intelligent AWD system, now taking the system's name into their
model designations: 328i xDrive Sedan and Sports Wagon, 335i xDrive
Sedan. The Coupe models also have xDrive.
At the core of this permanent AWD system is an electronically
controlled multi-disc clutch that steplessly varies torque
distribution between the front and rear wheels, and does so with
near-instantaneous speed. xDrive doesn't just optimize traction; it
can also enhance both agility and stability on grippy as well as
slippery road surfaces..
Superlative chassis technology;
Active Steering optional on 335i models.
Part and parcel of BMW's
tradition as The Ultimate Driving Machine is sophisticated chassis
technology. All 3 Series models have BMW's patented double-pivot
strut-type front suspension with aluminum components on rear-wheel
drive models for reduced unsprung weight. The rear suspension is a
5-link system engineered for a unique combination of agility and
BMW's steering is just as essential to the driving experience. All 3
Series models come standard with a hydraulic power-steering system
whose road feel and precision are legendary; optional on 335i Sedans
is Active Steering, which varies both the steering ratio and power
assist to further enhance agility, particularly at low to medium
driving speeds. Active Steering is another of those BMW innovations
that truly has to be experienced to be believed.
Optimized occupant protection:
including new Active head restraints on the front seats.
The 3 Series safety
concept is based on a solid and rigid body structure that utilizes
high-strength steels and targeted deformation elements to channel
and absorb collision forces in the most effective way for crash
safety. Specific safety equipment and systems include 3-point safety
belts and adjustable head restraints at all (five) seating
positions. LATCH attachments for child safety seats are standard at
the outboard rear seating positions.
New for 2009 are Active front head restraints, which in a rear-end
impact employ fast-acting pyrotechnic activation to pivot the
restraints' forward portion into close proximity with the occupants'
heads: the head restraint, or headrest, moves up to 60 mm/2.4 in.
forward and 40 mm/1.6 in. upward. This reduces their heads' rearward
motion, lessening the likelihood of whiplash or other head/neck
Standard airbag equipment in all current 3 Series Sedans and Sports
Wagons includes 2-stage, optimally configured front-impact airbags;
front-seat side-impact airbags; and a front-to-rear, curtain-type
Head Protection system deployed from the interior ceiling.
Advanced forward illumination
contributes to active safety.
contribution to active safety, that is the avoidance of accidents,
is Xenon Adaptive headlight technology, standard on 335i/335d models
and optional on 328i models. In addition to the greater luminous
power of Xenon lights, Adaptive means that the headlights "steer"
with the front wheels, governed by the vehicle's speed and the "yaw
rate" at which its direction is changing. This occurs at all speeds
and is especially beneficial at speed on curving rural roads at
Newly included on Sedans and Wagons with the Adaptive headlights are
Cornering Lights, which direct an angled beam at each front corner
to assist in situations of low speed and sharp turns. Additionally,
on U.S. models both of these lamps illuminate when reverse gear is
engaged. Also included is auto-leveling, which maintains accurate
aiming with changing vehicle loading, acceleration and braking to
reduce glare to oncoming motorists.
Class-leading automatic climate
BMW's automatic climate
control provides both effective automatic operation and a high
degree of manual "override" control when desired. The 3 Series
system is of recent design that incorporates highly refined airflow
that is both high-volume and quiet. Fuzzy logic assists in effective
temperature regulation, separately for the driver and passenger
sides. Other features include activated-charcoal microfilter
ventilation; temperature- and volume-controlled air to the rear
passenger compartment; a bi-directional solar sensor to account for
solar effects; automatic air recirculation when excessive air
pollution is sensed; automatic reduction of blower speed when the
vehicle comes to a stop; and a misting sensor that detects
windshield fogging and adjusts system operation to clear it up.
The design: unique, unmistakable,
Subtle new details
accent 3 Series' dynamic character.
New headlights, taillights and side sills.
Even better ergonomics and esthetics inside.
The current 3 Series,
already strong on BMW dynamism and identity, now gains an additional
measure of both by virtue of discreet updates and refinements. At
the rear, a widened track enhances these vehicles'
planted-on-the-road stance; careful and subtle modifications to the
front, sides and aft end make the total design even more harmonious.
At the front. A new, bolder front spoiler/bumper ensemble imparts
sportier, stronger character. Its center air intake is larger than
before, enhancing the air supply for mechanical components; upswept
lines in the lower air intakes, the bumper itself and the newly
shaped headlight clusters emphasize the wide stance. Double
longitudinal hood lines, more 3-dimensional than ever, rise toward
the A-pillars and frame the hood's power dome. New lighting features
include the layered turn-signal lenses, and on models with Xenon
Adaptive headlights, BMW's distinctive luminous rings now serve as
Daytime Running Lamps (on all models, they also function as parking
lights). The optional Park Distance Control now includes front and
rear monitoring.; formerly PDC was offered on the 3 Series in a
In profile. The lower character line that runs from just behind the
front wheel well to just ahead of the rear wheel well, is more
prominently contoured and strongly expresses the low stance. On
Sport Package-equipped models, new high-gloss Shadowline (black)
trim more elegantly frames the side windows. And new wheel designs
freshen the 328i models' 16-in. and the 335i/335d models' 17-in.
At the rear. Restating BMW's traditional L-form are the taillight
clusters of both Sedan and Sports Wagon models. Their two main
segments, for the taillights and turn signals, are composed of LED
rows for an even higher-tech look than before. On Sedans, the
trunklid is newly shaped to go with the new taillight design. And
the 0.6-in.-wider rear track does its part to strengthen an already
New colors. BMW paint colors are notable for their richness and
eye-catching appeal. A total of 12 colors are offered with three new
metallics for '09: Space Gray, Tasman Green and Blue Water.
Interior: newly refined materials, surfaces and colors. Here too,
subtle updates and refinements mark the newest 3 Series Sedan and
Sports Wagon interiors. Materials and surface quality add appeal;
certain functional elements including the optional iDrive controller
and climate and audio controls offer refined appearance and tactile
The doorsill trims with their distinctive BMW script are new. The
somewhat smaller iDrive controller has a fine galvanic surface, and
is newly surrounded by the direct-select keys that enhance iDrive's
user-friendliness. There's a larger storage tray in the center
console including the auxiliary audio input and providing an
appropriate place to lay an audio source. Door-panel design has been
refined too; on the driver's door the power-window and -mirror
controls have been moved 2 cm rearward for an easier, more natural
Colors and color contrasts have been improved, as well. Three new
colors for the optional Dakota leather upholstery are offered:
Oyster, Saddle Brown and Chestnut Brown. Interior trim choices are
updated, too, with a new Fine Line aluminum trim replacing the
former brushed aluminum and Light Burl Walnut replacing Light Poplar
among the available wood trims.
Lastly, a heated steering wheel - much appreciated by drivers of
other BMW Series in winter weather - has been added to the optional
Cold Weather Package for all models.
In general, the interior space - with its attractive interplay of
convex and concave surfaces, its sporty elegance and
technology-oriented esthetics is more appealing than ever.
BMW Efficient Dynamics in the new 3 Series: BMW Advanced Diesel with
Blue Performance meets emission standards in all 50 states.
6-cylinder twin-turbo diesel engine in 335d Sedan.
BluePerformance technology meets diesel-engine emission
standards in all 50 U.S. states.
In its competitive
field, BMW is known for powertrains that achieve an outstanding
combination of performance and fuel efficiency. In addition to the
commendable mileage ratings of the 3 Series' gasoline engines, the
newest evidence of BMW's EfficientDynamics approach is the new
twin-turbo diesel engine of the likewise new 335d Sedan model, which
combines the new-age diesel performance that has swept European
motoring in recent years with truly remarkable Miles per Gallon.
The new 335d Sedan: power, torque
and remarkable fuel efficiency.
All with refinement and sound worthy of a BMW.
In Europe, where fuel
prices have historically been - and remain - much higher than in the
U.S., vehicle manufacturers have achieved dramatic gains in the
performance, smoothness, quietness and emission control of diesel
while maintaining the diesel's historic superiority in fuel
efficiency. Now, with the new 335d Sedan, BMW brings this progress
to the U.S., with brand-new technology that meets the U.S.'
strictest emission standards.
Like all '09 BMW gasoline engines, the 335d's new diesel is
constructed with a weight-saving aluminum cylinder block - something
that's not taken for granted given the diesel's much higher
compression pressures. (All BMW engines have aluminum cylinder
heads.) It is an inline 6-cylinder engine maintaining a defining BMW
tradition that means exceptional smoothness and unique sound.
In addition, several diesel-specific technologies of this new engine
contribute to its achievement of true high performance, diesel fuel
economy and clean exhaust:
Common-rail direct fuel injection. One of the most important
innovations of recent diesel development, this has replaced the
individual-cylinder or distributor-type injection systems of earlier
Common Rail (CR) means that a single, very high-pressure
fuel-delivery pump supplies all cylinders, the fuel traveling along
a common "rail" or distributor line. From there, fuel is injected at
extremely high pressure (180 bar/2645 lb./sq in.) directly into the
The basic novelty of common-rail injection was to divorce the
production of fuel pressure from the actual injection process; this
was necessary to give the diesel engine what gasoline engines have
long had, namely completely electronically controlled fuel
injection. CR also facilitates multiple injections per combustion
cycle. In all, this was a breakthrough that made possible dramatic
strides in diesel power, efficiency and emission control.
Piezo injectors. A further breakthrough, already applied by BMW in
the 335i (and other BMWs) models' twin-turbo gasoline engines. With
direct injection, the injectors - that critical component injecting
fuel into each cylinder's combustion chamber - are subject to
especially high temperatures and pressures. Instead of most
injectors' conventional electrical valves, a "stack" of piezo
crystals reacts lighting-fast to impulses from the engine
electronics governing the injector needle's opening stroke and
duration for ultra-precise control. This, too, facilitates major
advances in fuel economy and emission control, in gasoline, as well
as diesel engines.
Variable Twin Turbo technology. In contrast to the two small,
equal-size turbochargers of BMW's twin-turbo 6-cylinder and V-8
engines, the diesel employs two turbos of different sizes.
At low engine speeds, intake air does pass through the large turbo,
but it's the smaller, lower-inertia one that does the air
compressing (turbocharging). Thanks to its optimum efficiency within
this rpm range, it provides effective boost for driving from a
standstill up to modest acceleration rates and driving speeds. So it
is that this engine develops a good 390 lb-ft. of torque at as low
as 1500 rpm - a remarkable achievement that will amaze first-time
335d drivers and continue to thrill those who drive this BMW
With increasing engine speed, the larger turbocharger begins to take
over: first as a pre-compressor for the smaller one, then
progressively until it becomes the primary turbo. The engine reaches
its maximum of 425 lb-ft. by 1750 rpm, then maintains this immense
torque level until 2250 rpm going on to reach its peak power of 265
hp at 4200 rpm.
Diesel combustion, power and torque characteristics. In its most
basic distinction from gasoline engines, a diesel engine achieves
its combustion not with a sparkplug, but by much "harder"
compression of the fuel-air mixture; the 335d engine, for example,
has a compression ratio of 16:5:1, vs. 12.0:1 in today's
ultra-high-performance BMW M gasoline engines and the 10.2:1 of the
335i twin-turbo gasoline unit. For one thing, this requires a
significantly stronger engine structure; indeed, the 335d engine
weighs more than its 335i counterpart.
The diesel combustion process also produces very different torque
and power characteristics. Whereas the 335i engine reaches a maximum
torque of 300 lb-ft. @ 1400-5000 rpm and a maximum power of 300 hp @
5800 rpm, the 335d attains its maximum torque of 425 lb-ft. @
1750-2250 rpm and its maximum power of 265 hp @ just 4200 rpm. In
general, diesels have this low-speed-torque, lower-rpm character and
in their vehicular application, they are geared differently. The
335d, for example, comes only with automatic transmission - an
automatic is the ideal partner for a diesel engine - and its final
drive ratio is 2.81:1, vs. 3.46:1 for the 335i with automatic
Diesel engines also employ a different fuel, the product of a
different refining process from that of gasoline. The two fuels are
not interchangeable; gasoline cannot be used in a diesel engine, and
vice versa. Their prices typically diverge; at any time or in any
location, demand may be different for the two, and government
taxation policies for gasoline and diesel fuel also diverge.
Stellar pulling moxie, full-bore acceleration - and fuel efficiency.
The huge torque output of 425 lb-ft. at relatively low engine speeds
speaks for itself; 335d drivers will marvel at this engine's robust
response at low to medium speeds. The peak power output of 265 hp
also speaks for itself, as does the resulting 0-60-mph time of 6.0
sec. While official EPA mileage estimates are not yet available,
preliminary tests indicate 23 mpg city and 33 highway.
Most advanced exhaust gas
management: SCR catalyst with AdBlue injection.
BMW Advanced Diesel with
BluePerformance optimizes emission management by incorporating an
oxidation catalyst placed close to the engine, a diesel particulate
filter housed in the same unit, and an SCR catalyst with urea
injection. Apart from filtering out even the smallest particles from
the flow of exhaust gases, this combination ensures effective
reduction of nitric oxides (NOX) by way of a chemical reaction
within the exhaust system initiated by the injection of a small dose
of urea referred to as AdBlue. The ammonia (NH3) generated in this
process within the SCR catalyst subsequently converts the nitric
oxides (NO and, respectively, NO2) in the exhaust gas into
environmentally compatible nitrogen (N2) and vapor (H2O).
BMW has developed a two-tank system for AdBlue ensuring convenient
use of this new technology with all the benefits and ease required
by the customer: The amount of AdBlue required in each case is drawn
from the active tank comprising approximately 1.6 gallons by means
of a dosage pump. And since the urea solution would freeze at a
temperature of ?11oC, this active tank, as well as the dosage pipes
AdBlue technology by BMW: reduced
emissions without additional service appointments.
The active tank is
connected to a second reservoir, the so-called passive tank. With
its additional capacity of approximately 4.5 gallons, this passive
tank offers a plentiful supply of the urea solution required within
the car. The average range provided on this supply capacity is
indeed sufficient to have the tank system replenished as part of
normal scheduled maintenance.
From the active tank AdBlue is delivered to the dosing valve and
atomized into the exhaust emissions. Consistent distribution of
AdBlue within the flow of exhaust emissions is ensured by the SCR
mixer. The ammonia generated in this way in the hot emission gas
subsequently acts in the SCR catalyst as a reduction agent and
converts environmentally harmful nitric oxides into nitrogen and
water vapor in a process referred to as selective catalytic
This process gives the special SCR catalyst its name with the SCR
system as such being masterminded by highly efficient engine
management. A nitric oxide sensor, finally, provides information on
the concentration of NOX in the exhaust emissions.
The large amount of AdBlue provided in the reservoir enables the
customer to go on driving as before without having to change service
intervals or observe any particular requirements, thus benefiting
from the advantages of this environmentally friendly emission
technology throughout the entire running life of the car without any
additional service or visits to the workshop. During the first four
years or 50,000 miles, the replenishment of AdBlue will be covered
as part of the BMW Scheduled Maintenance program: not only will
there be no additional inconvenience, but no addition cost during
Other 3 Series powertrains: smooth, strong and efficient 6-cylinder
gasoline engines, diverse transmission choices.
328i and 335i
models powered by two distinct inline 6-cylinder engines.
Dynamic performance in the great BMW tradition.
Many transmission choices, all with 6 speeds.
Two quite distinct
inline 6-cylinder gasoline engines power all other 3 Series models;
these remain unchanged in the new '09 models.
328i models: 3.0-liter inline
6-cylinder engine, naturally aspirated.
In the 328i models -
Sedan and Sports Wagon, rear-wheel- and all-wheel-drive models - a
3.0-liter unit with advanced, weight-saving magnesium/aluminum
composite construction and Valvetronic variable valve lift provides
smooth, sonorous and fuel-efficient power.
Valvetronic, a patented BMW innovation, varies valve lift to
regulate engine power; when the driver steps down on the accelerator
pedal, instead of a throttle opening wider, intake-valve lift
increases. A throttle imposes a restriction to incoming air;
Valvetronic eliminates this restriction, significantly enhancing
efficiency particularly at low to medium speeds. This is reflected
in excellent fuel economy, plus very spontaneous response to that
accelerator pedal. Valvetronic also enhances engine smoothness in
idling and gentle driving, and makes for excellent cold starting.
This engine delivers 230 hp @ 6500 rpm and has a 7000-rpm redline,
so it is in the great tradition of smooth, powerful and high-revving
BMW gasoline engines. Yet its torque peak of 200 lb-ft. occurs at
relatively low engine speed for a gasoline engine - 2750 rpm - so
it's also a responsive partner in everyday driving, not requiring
frequent shifting to maintain a brisk pace with the standard 6-speed
manual transmission. 0-60-mph times for the 328i Sedan are 6.3 sec.
for the manual, 6.9 sec. for the automatic; 2008 EPA city/highway
mileage ratings are 18/28 mpg with manual, 19/28 with automatic.
Acceleration times and EPA ratings vary for the Sports Wagon, and
for the Sedan and Sports Wagon in their xDrive (all-wheel-drive)
335i models: also 3.0-liter inline
6, twin-turbo, even more brilliant performance.
The 335i Sedan and its
AWD stablemate 335i xDrive are powered by a totally distinct
3.0-liter inline 6, with an aluminum block, different bore and
stroke dimensions, and most importantly twin turbochargers.
High-pressure direct fuel injection with piezo injectors, a concept
shared with the 335d diesel engine, and special turbo-related
cooling features complete the description of an engine that has
garnered almost delirious praise in the enthusiast media and beyond.
It develops a full 300 hp @ 5800 rpm, has the same 7000-rpm redline
as the 328i engine, and generates a fulsome 300 lb-ft. of torque all
the way from 1400 to 5000 rpm - a somewhat diesel-like
Here the twin turbochargers are both small, each of them serving 3
of the 6 cylinders. Their smallness enables them to respond quickly
to the driver's demands reducing turbo engines' historical "turbo
lag" to a minimum. This engine does not have Valvetronic, as
turbocharging works best on a gasoline engine with a conventional
throttle. On-the-road performance is stunning: 0-60 mph in just 5.4
sec. with manual transmission, 5.6 with automatic; and that broad,
generous torque band produces abundant acceleration even at lower
speeds in the upper gears. EPA mileage ratings are equally
impressive: 17/26 mpg with either transmission for the 335i,
slightly less for the xDrive version.
Transmission choices: 6-speed
manual or automatic, shift paddles optional.
All 3 Series
transmission choices are 6-speeds. The manual gearbox, standard on
all models, is engineered to provide what buyers want when they
choose it: precise control and a high level of driving pleasure.
BMW also places a high priority on active driving pleasure with its
automatic transmissions. Recent refinements to the 3 Series'
automatics have improved their sportiness, precision and efficiency:
a torque converter that slips less, quicker shifting, finer
adaptation to driving style and conditions. All BMW automatics
include a Sport mode that quickens shifting and holds the lower
gears longer; and a Manual mode that allows the driver to take
charge of virtually all shifting.
Steering-wheel-mounted shift paddles are added on all automatic 3
Series models with the Sport Package, and include a Direct Selection
feature: When the driver is motoring along in Drive and makes a
shift via paddle, the transmission goes into the Manual mode.
BMW iDrive, 2nd generation: new graphics and controls.
concept, high-resolution 8.8-in. control display.
Optimized menu structures, high-resolution graphics, expanded
range of functions.
Greater convenience and more intuitive operation via
direct-select keys at the controller, plus more Programmable
In the 3 Series, BMW's
iDrive system of controls and displays is offered in combination
with the optional Navigation system. In the new 3 Series Sedans and
Sports Wagons, iDrive enters its 2nd generation building upon this
pioneering development, while making it more natural, more
intuitive, simpler and more elegant in its functionality - and more
esthetically pleasing and enjoyable. In offering this new generation
of iDrive, the 3 Series joins the new 7 Series that is also being
introduced this autumn.
More intuitive operation, expanded
With the 2002 7 Series,
BMW initiated a new direction in the control of vehicle features and
functions; via a multi-menu color display and a mouse-like
controller usable by driver and passenger alike, a potentially
crowded landscape of buttons and knobs was supplanted by a
computer-logic control path.
An overarching attribute of iDrive was the separation of control
(via the console controller) and display (the centrally placed
iDrive monitor). This basic arrangement remains; the controller has
been further developed and the display has evolved markedly.
Positioned centrally in the instrument panel, the new control
display sets higher standards for logical, readily understood menus
and attractive graphics. The controller has been refined for
comfortable, intuitive selection and activation of functions via
standardized turn, push and tilt motions, while being augmented with
new direct-selection keys for specific menus, plus more of the
Programmable Memory Keys that were added to the system in the 3
Series in 2007-08.
Greater functionality, satisfying
to use: controller with direct-selection keys.
Benefiting from the
newest biomechanics R&D, the state-of-the-art controller operates
with tactile precision and clearly structured motions. New control
elements, menu schemes and graphic representations in the control
display become evident upon first use, yet user appreciation grows
over the longer term. A graphic depiction of the controller in the
display itself helps orient the user to the next control step; the
rotation, pressing and tipping motions generally correspond to those
of a computer mouse.
Thus interpreted, rotation of the controller takes the user through
menu selections; pressing it makes the choice. Tilting the
controller to the left or right effects navigation through various
menu levels. Via clear graphic organization in the form of stacked
layers and onscreen depiction of controller movements, the user
enjoys highly intuitive navigation. All menus are structured
according to a consistent scheme, so that one is almost immediately
at ease; menus are broad so that the user can view relatively
numerous options without switching to another level. Also, functions
are arranged so that in longer-term use the most important options
are reached more rapidly.
An additional new refinement is four direct-selection keys, placed
adjacent to the controller, for the most frequently used menus.
These allow quick selection of CD, radio, phone and navigation
menus, and are augmented by three further keys of general utility:
one takes the user directly to the start menu (MENU), one to the
most recently active menu (BACK), and the third (OPTION) presents
various options within the current area. Thus searches are likely to
be shorter, or unnecessary.
Familiar and proven, yet now more
useful: Programmable Memory Keys.
An iDrive enhancement
recently introduced in various BMW models represents a further user
convenience: Programmable Memory Keys. When first introduced, there
were six of them; now there are eight. Lined up above the audio
controls, these allow the user to capture and store favorite or
frequently used functions (radio stations, phone numbers, navigation
destinations for example) on various keys and recall them instantly.
The stored functions can be as specific and detailed as a navigation
map in the preferred scale or an audio balance setting. And because
the keys are sensitive not just to being pressed but also to being
merely touched, one can see the stored function on the control
display by lightly touching the key. If it's the right one, the user
need only press the key and it's there, ready to use.
High-resolution display, preview
maps and full-screen images.
With its 8.8-in.,
high-resolution monitor, the new iDrive displays remarkably
attractive images. It's a system appropriate to the vehicle it's in,
achieved via up-to-date hard- and software. White-on-black menu
lists; effective symbols and icons; contemporary graphics; and
clear, consistent color-coding are among the elements that enhance
not only function but also esthetics.
Menu structures, too, make finding desired functions easier. In the
Start Menu, all functional areas served by iDrive are listed.
Selecting a given item leads to its menu layer, where the options of
that level are also listed. This consistency in navigation assists
in orienting the user, as does the "stacking" of menu layers in the
display. Visual assists further contribute to clarity. And if the
user gets to a place where he or she didn't mean to be, the Back key
usually reverses the error.
This overall refinement
of functionality means simpler and more enjoyable use of the
optional Navigation. Full-screen map displays offer outstandingly
detailed views of the geography; maps as well as specific symbols
can be shown in 3-dimensional form. Selected points of interest
along the travel route appear with near-photographic realism.
Mere input of destinations reveals the new system's impressive
capabilities. If the destination appears on a list in the system, a
preview map appears as the user scrolls the list; this can help
distinguish between places with similar or identical names. If a
destination (or a phone number) needs to be entered manually, this
is done with a new, circular "speller" that makes the entry go more
Convenient combination of voice
entry and controller operation.
Yet, another iDrive
innovation is its ability to combine voice and controller entry
called Multi-mode Input. The user can go back and forth between the
two methods, while actually inputting; indeed, voice recognition can
remain active during input via controller and the user can modify an
input via voice. Voice recognition - BMW calls it Voice Command - is
activated by its function key on the steering wheel, and
de-activated either upon completion of the action or by pressing the
key again. Voice Command is simplified by visual display of the
available commands, yet its capabilities go further in that numerous
synonyms of these commands are also recognized.
This newly enhanced iDrive introduces a very significant step
forward in the operation of automotive features and functions.
Greater efficiency, improved logic and clear, attractive displays
help define and advance the 3 Series' unique product character. The
new iDrive helps the freshened 3 Series Sedans and Sports Wagons
create a user experience that is truly unique.
BMW Assist: networking for greater
convenience, safety and security.
networking of driver, vehicle and driving environment.
Expanded range of services and capabilities.
BMW pioneered Navigation
as an automotive feature in 1994, for the first time bringing data
from outside the vehicle into the driver's cabin. In 2002, the 7
Series introduced iDrive integrating GPS Navigation into a more
comprehensive grouping of vehicular functions and capabilities. For
2009, this evolution continues with introduction of the
2nd-generation iDrive, further development of the Navigation
system's potentials and an expanded range of telematics services
within the BMW Assist system.
In its most fundamental precepts, BMW Assist emphasizes "warning and
serving, not intervening." The driver (or more generally, user)
retains the responsibility for his or her vehicle. It lightens the
user's burdens by offering as much information and assistance as the
user desires in each specific situation.
BMW Assist: telematics enhance
users' convenience, safety and security.
BMW Assist safety and
convenience services are offered as the BMW Assist Safety Plan
(standard with BMW Assist) and Convenience Plan (an option expanding
BMW Assist). The Safety Plan is in effect for the first 4 years or
50,000 miles from new and includes the following services:
Automatic Collision Notification. In the event of an airbag
deployment or severe impact, the BMW Call Center is notified and
emergency services are deployed as appropriate. New for '09: if the
collision is of a certain severity or worse, the system transmits
the vehicle's location and specifications, as well as data from
several onboard sensors that define the type of collision and
probability of occupant injury.
Emergency Request. Vehicle occupants may request emergency services
24/7 by pressing the SOS button.
Enhanced Roadside Assistance may also be summoned from the vehicle
in a similar manner. Adds features and services beyond the
4-year/unlimited-miles Roadside Assistance that is standard with
every current BMW model.
Remote Vehicle Unlock from the Call Center when the user gets locked
Stolen Vehicle Recovery. The user files a police report and notifies
the Call Center, which can remotely activate the BMW Assist system
to locate the vehicle and help police recover it.
TeleService automatically transmits key vehicle data to the
subscriber's preferred BMW center when the vehicle's Condition-Based
Service sensors detect a need for upcoming service; in turn the BMW
Center contacts the owner. The driver can also initiate a service
Customer Relations. Users can speak with BMW Customer Relations at
the push of a button.
The Convenience Plan, optional on a yearly basis, expands these
services by offering:
Directions, traffic and weather information.
Critical Calling. If the subscriber forgets to bring a mobile phone
or its battery is discharged, yet urgently needs to make a phone
call, four operator-assisted calls per year via the SOS button are
Concierge Service including travel planning, dining and hotel
reservations, shopping assistance and event tickets.
There are additional services for vehicles equipped with the
Real Time Traffic Information is received in the vehicle via an FM
data broadcast. It is processed in the system to notify the driver
of potential traffic problems on the programmed route, and offers an
alternate route or the option of automatic re-routing around the
problem. RTTI is available in more than 50 metropolitan markets in
the U.S; BMW provides it to customers for a minimum of 4 years
without recurring monthly bills.
Expanded Navigation capabilities. The new 2nd-generation iDrive
system incorporates many enhancements to Navigation capabilities.
Among these are directions to change lanes or make a turn at an
obscured intersection, 3-dimensional screens depicting topography
along the route and selected points of interest.
Bluetooth cellphone interface included with BMW Assist option. When
a BMW-approved cellphone is paired with the interface, BMW's
in-vehicle hands-free memory, dialing and calling features are
available to users. Voice Command, included with the Navigation
option, enables phone (and other) functions to be voice-activated.
In keeping with BMW's policy of accommodating contemporary
technological products and the evolving lifestyles that go with
them, the latest iPhone models are among the approved BMW cellphones.
BMW xDrive: intelligent all-wheel
drive that's infinitely
variable, satisfying agile, always reassuring.
BMW is the world's
most successful producer of premium vehicles with all-wheel
Now smoother and more precise than ever, thanks to modulated
brake intervention and torque compensation.
Available in three Sedan and Sports Wagon models, plus two
- particularly those who drive in snowy winter conditions - want
all-wheel drive. In the 3 Series, five models - with new "xDrive"
model designations - incorporate BMW's unique and advanced AWD
system of the same name.
This permanent, electronically controlled system varies the split
between front- and rear-wheel driving torque according to driving
conditions to produce an incomparable degree of comfort, traction
and agility. Via a smooth, precisely controlled central multi-disc
clutch, it directs torque to the wheels where the traction is best,
reacting amazingly quickly to each change in driving conditions.
In most normal driving situations, xDrive apportions 40% of the
driving torque to the front wheels, 60% to the rear to provide a
typical BMW rear-wheel-drive handling feel. Sensors continuously and
sensitively monitor the four wheels, detecting even the tiniest
amount of slip; torque distribution adjusts in fractions of a second
to match changing conditions. It all occurs so quickly, in fact,
that the system almost seems to be anticipating slip; the driver is
unlikely to perceive the need to adjust the torque split before
xDrive accomplishes it.
Enhancing xDrive's quick and precise action is the networking of
xDrive and Dynamic Stability Control, the traction and stability
system that's standard on all BMW models. As part of BMW's overall
Integrated Chassis Management (ICM), this powerful and capable
networking helps calibrate xDrive torque distribution and other
chassis functions to instantaneous conditions. Thus xDrive and DSC
react to varying road traction or abrupt steering, braking or
acceleration by the driver, always endowing the vehicle with optimum
stability and agility.
Via ICM, xDrive and DSC detect any incipient excessive over- or
understeer, adjusting the front/rear torque split to avoid these
tendencies. If undesirable oversteer is sensed, the multi-disc
clutch is completely closed, sending the maximum possible torque to
the front wheels. If excessive understeer is detected, xDrive opens
the clutch completely, sending all the torque to the rear wheels. In
true BMW tradition, the driver enjoys optimum vehicle dynamics under
a wide range of driving and road conditions. Finely dosed
application of individual wheel brakes compensates for side-to-side
traction variations, as well: this aspect of DSC was improved upon
the current 3 Series' introduction, via new analog brake actuation
in this situation, as well as other stability-related or anti-lock
