Whitby. BMW Group Canada is pleased to announce today that two new BMW
high-performance diesel models will expand the BMW lineup this fall.

BMW 335d and X5 xDrive35d models will introduce BMW's new Advanced Diesel with
BluePerformance to Canada in the form of a 3.0-litre straight-six diesel engine
with Variable Twin Turbo Technology and Selective Catalytic Reduction (SCR)
combustion management system with urea injection.

With a maximum output of 265 hp and peak torque of an astonishing 425 lb-ft.,
the 3.0-liter six with Advanced Diesel with BluePerformance will not only
provide sports-car-like acceleration and driveability, but offer up a whole new
level of fuel efficiency and emission reduction in both models.

Preliminary performance figures (based on provisional U.S. figures) for the BMW
335d indicate a potent acceleration capability of 6.2 seconds to achieve 0-100
km/h, nearly matching the gasoline-engined BMW 335i figure of 5.7 seconds. The
tenacious performance of the BMW 335d is complemented by an unprecedented fuel
economy rating (also based on provisional U.S. figures) of10.2/7.2 litres per
100 km (city/highway), an advantage of 35.3% and 26.9% (city/highway),
respectively, over the gasoline engined variant.

Parallel preliminary acceleration figures for the BMW X5 xDrive35d show a 0-100
km/h time of 7.2 seconds, nipping the BMW X5 3.0si's gasoline-engined
stablemate's 0-100 km/h time by over a full second. This exhilarating diesel
SAV performance is accompanied by a particularly thrifty fuel consumption
rating (based on provisional U.S. figures) of 12.4/9.4 litres per 100 km
(city/highway), an improvement of some 26.7% and19.0%, respectively, over the
gasoline-engined X5 3.0si.

Canadian versions of the BMW 335d and X5 xDrive35d are expected to achieve
similar performance and fuel economy ratings as their U.S. counterparts.

Use of SCR technology to reduce nitrogen oxides (NOX) ensures full compliance
with the Canadian emission standards along with those of California and other
US states, where the BMW Advanced Diesel with BluePerformance will be
introduced as a so-called 50-state model (BIN5).

The world's most sporting straight-six diesel
BMW's 3.0-litre straight-six diesel engine with Variable Twin Turbo has won the
International Engine of the Year Award several times, over and above other
prizes and acknowledgements. The engine is featured in a broad spectrum of
exciting European BMW models and is now continuing its global story of success
as the BMW Advanced Diesel with BluePerformance.

The now well-recognized Variable Twin Turbo diesel utilizes a small,
low-inertia turbocharger deploying at low engine speeds, working in combination
with a second, larger turbocharger, kicking in at higher engine speeds.
Masterminded by a high-performance electronic control unit, the twin turbos
precipitate a linear, lag-free delivery of torque, spooling up to the maximum
of 425 lb-ft at just 1,750 rpm.

Further technical highlights are an aluminum crankcase and third-generation
common-rail direct fuel injection, with fuel being delivered into the
combustion chambers by means of piezo-injectors for particularly precise fuel
metering with the smallest volume of pre-injection. This, in turn, ensures a
particularly clean injection process with optimised fuel consumption and
emission figures as well as further enhancement of running smoothness.

SCR catalyst with AdBlue injection.
To optimise emission management, Advanced Diesel with BluePerformance
incorporates an oxidation catalyst placed close to the engine, a diesel
particulate filter housed in the same unit, and an SCR catalyst with the urea
injection. In addition to filtering out even the smallest particles from the
flow of exhaust gases, this combination ensures effective reduction of nitrogen
oxides (NOX) by way of a chemical reaction within the exhaust system initiated
by the injection of a small quantity of urea referred to as AdBlue. The ammonia
(NH3) generated in this process within the SCR catalyst subsequently converts
the nitrogen oxides (NO and, respectively, NO2) in the exhaust gas into
environmentally compatible nitrogen (N2) and vapour (H2O).

In integrating AdBlue technology, BMW has developed a two-tank system ensuring
convenient use of this new technology - the process completely transparent to
the driver. The required quantity of AdBlue is withdrawn via pump from a
6-litre "active" tank which is also variably heated, along with delivery lines,
to ensure low-temperature efficiency.
The active tank is connected to a second "passive" reservoir. With its
additional capacity of approximately 17 litres, the system capacity and refill
range has been engineered to coincide with engine oil change intervals typical
of normal driving - precluding, in most cases, any special service requirements
and optimizing customer convenience.

From the active tank, AdBlue is delivered to the dosing valve and atomised 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 acting in the SCR catalyst as a
reduction agent and converting environmentally harmful nitrogen oxides into
nitrogen and vapour in a process referred to as selective catalytic reaction.

The introduction of Advanced Diesel with BlueTechnology in Canada represents
another important milestone in the ever-expanding strategy of BMW Efficient
Dynamics to ensure industry leadership in the development of dynamic and
environmentally sensitive solutions for current and future mobility.

BMW's competence in diesel technology:
A story of success since 1983.
The performance and fuel economy offered by new BMW Advanced Diesel with
BluePerformance is a further example of the exceptional potential this engine
concept has to offer. In recent years BMW has worked more thoroughly and
consistently than any other manufacturer worldwide to promote and further the
development of its EfficientDynamics strategy. As a result, BMW has
consistently enhanced the benefits and attractiveness of diesel technology,
increasing engine output (performance), while reducing fuel consumption and
emissions.

Through their unique motoring refinement and smoothness - a feature which was
thought to be impossible with a diesel engine - BMW's diesel engines stand out
among the competition, setting the industry standard for diesel engine
technology today.

The story of success of BMW's diesel engines is characterized by numerous
milestones in technical development, dating back to 1983. Back then BMW
presented the first inline-six diesel in the history of the company, with
maximum output of 85 kW/115 hp and peak torque of 210 Newton-metres/155 lb-ft.
The BMW 524td that featured this engine was acknowledged as the fastest diesel
of its time and was the last BMW diesel model to be sold in North America.

In the years to come BMW's engine development specialists enhanced a wide range
of innovations, ensuring their alignment with series production standards,
increasing power and performance, reducing fuel consumption and emissions in
the process. In 1987, for example, BMW introduced DDE Digital Diesel
Electronics followed three years later by BMW's first diesel engine with an
oxidation catalyst.

BMW diesel engines:
Making a unique contribution to The Ultimate Driving Experience.
From the outset, BMW's engine development specialists recognized the potential
of the diesel in enhancing motoring efficiency. They focused on the unique
performance characteristics offered by the diesel in order to provide a new
concept of The Ultimate Driving Experience. Above all, the development
specialists used the performance of the diesel engine to develop superior
torque from low engine speeds.

As a result, the BMW diesel was soon able to offer its unique sporting
character - in everyday driving situations, as well as on the race track.
Indeed, it was this performance and reliability which made a BMW 320d the
superior winner of the 24 Hours of Nürburgring as early as in 1998.

In the same year BMW presented its first diesel engine with direct fuel
injection ensuring even greater spontaneity in the development of power. In the
process, the precise dosage of fuel helped to reduce fuel consumption and
optimize combustion in the interest of even greater smoothness and refinement.
Ultimately, given these qualities, the BMW diesel was appropriately prepared
for the luxury performance class, with the first V8 diesel engine featuring
direct fuel injection, which made its debut in the BMW 7 Series luxury sedan in
1999.


Milestones in progress:
Common-rail direct fuel injection, Variable Twin Turbo Technology,
maintenance-free diesel particulates filter, BluePerformance.
In the years that followed, BMW made significant - perhaps revolutionary -
progress in the areas of injection technology and diesel turbocharging: As
early as 2001, the second generation of common-rail fuel injection pumped fuel
into the combustion chambers at a pressure of up to 1,600 bar. In 2004, the BMW
535d became the first car to feature an inline-six diesel with Variable Twin
Turbo Technology.

BMW also introduced the second generation of the diesel particulates filter now
featured as standard in all of the diesel models from Germany's premium
manufacturer. The exhaust gas-cleaning unit is positioned directly on the
exhaust manifold itself in order to ensure optimum efficiency very quickly and
smoothly. The particulates filter does not require any maintenance and
regenerates itself by incinerating the diesel particles. This filtering
function is performed at all engine speeds and under all loads, without any
reduction of engine power or increase in fuel consumption.

BMW's current range comprises no less than seven diesel engines, including
four-cylinder, six-cylinder and V8 versions. Both the six- and four-cylinder
engines have aluminum crankcases helping to significantly reduce the weight of
these engines. A traditional handicap of the diesel engine, which adds weight
due to the use of a cast iron crankcase (a much heavier material than
aluminum), has nearly been phased out completely. The reduction of weight
enhances the car's agility and, as a result, the sporting character of BMW's
diesel models.

Comparing the first six-cylinder BMW diesels from 1983 with the most powerful
diesel engines of today, one can easily appreciate the progress made. Consider
the following facts and figures:
Maximum output of the inline-six engine is up 135 percent, maximum torque is up
an even more impressive 170 percent. And despite this immense increase in
power and muscle, average fuel consumption of the 3.0-liter engine featuring
Variable Twin Turbo Technology is 20 percent lower than diesel engines of
1983. At the same time, exhaust emissions have been reduced dramatically,
thanks to several new technologies. Indeed, a BMW diesel in the 2008 model
year generates only 1 percent of the particulate emissions originally contained
in the exhaust gas of a 1983 diesel model.

Despite these impressive facts and figures, BMW is continuing to upgrade the
diesel engine to an even higher standard, and BMW Advanced Diesel with
BluePerformance marks the next stage of development.

The new BMW 335d and X5 xDrive35d, featuring Advanced Diesel with
BluePerformance, will have its North American premiere at the 2008 Detroit
International Auto Show. Pricing and additional technical details will be
communicated closer to market launch in the fall of 2008.
