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.

Highlights.
• 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 2009.

Segment original remains segment leader.

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 -
• A subtle exterior-design freshening
• Refinement of interior design and functions
• New and/or revised options
• A new generation of the iDrive control and display system
• Expansion of BMW Assist services
• An all-new turbodiesel engine in a new model - the 335d Sedan.

Fundamentally unchanged - 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 quintessentially BMW.

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 ¾ 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 Communications 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 Series
incorporates BMW Assist and TeleService functions (both included in the BMW
Assist TM and Bluetooth© system option). Automatic Collision Notification, 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 Assist Response Center the vehicle's
location and specifications, as well as data from several onboard sensors that
define the type of collision and probability of severe occupant injury. At the
same time, the response specialist attempts to establish a voice connection
with the vehicle occupants and will request dispatch of emergency services to
the vehicle's location 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 reassuring stability.

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 injuries.

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.

A significant 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 night.

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 control.

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, elegant.

• 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 rear-only version.

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. standard equipment.

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
road-gripping stance.

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 qualities.

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 reach.

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.

• New inline 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 engines...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 diesel engines.

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 cylinder.

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 regularly.

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 transmission.

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 are heated.

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
reduction.

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 that period.

Other 3 Series powertrains: smooth, strong and efficient 6-cylinder gasoline
engines, diverse transmission choices.
