BMW Efficient Dynamics - now also for the 3 Series

Munich. The BMW development strategy EfficientDynamics continues to be pursued
consistently with new models optimised for reduced fuel consumption and exhaust
emissions. For model year 2008, the launch of especially efficient engines also
in the high-volume BMW 3 Series will make a major contribution to the overall
reduction in exhaust emissions. By autumn 2007 around 40% of all BMW Group
(BMW, MINI, Rolls-Royce) cars sold in Europe come with maximum C02 emissions of
140g per kilometre. They confirm the obviousness of the measures that were
initiated in the BMW engineering departments 5 years ago.

In the model year 2008, the number of BMW Group vehicles with a maximum CO2
level of 140 g per kilometre increases to 22. Three of them are MINI models and
two of them belong to an additional BMW model line. This extension of the range
of especially low-emission models is made possible by the newly developed
4-cylinder petrol and diesel engines for the BMW 3 Series and the market launch
of the new BMW 123d and the new BMW 520d.

With its average consumption of 5.1 litres of diesel per 100 kilometres as
determined by the EU test cycle and a CO2 level of 136 g per kilometre, the BMW
520d sets new standards in its segment.

The new 1.6 litre 4-cylinder with direct injection in lean combustion operation
makes the most efficient of the petrol engines, resulting in outstanding levels
in terms of fuel consumption and exhaust emissions in the new BMW 116i (5,8
litres, 139 g). The 4-cylinder diesel engine with Twin Turbo in the new BMW
123d (5.2 litres, 138 g) provides an especially fascinating combination of
driving fun and economy. There are also new engines available for the BMW X5,
the BMW X3 and the new BMW 6 Series which provide a unique relationship between
driving dynamics and economy as compared to the competition within their
respective vehicle categories.

The innovations developed as part of the BMW EfficientDynamics strategy are
available to customers as standard in all new BMW models. With the ongoing
introduction of new efficiency-increasing measures in all series, BMW is
ensuring that its technologies to reduce fuel consumption and exhaust emissions
will become as widespread as possible.

Increased dynamic performance, reduced CO2 - the result of a long-term strategy.

The variety of highly economic models across the various model series is the
result of the long-term and consistently pursued development strategy BMW
EfficientDynamics. Within the voluntary VDA commitment BMW reduced fleet C02
emissions already by 30 per cent between 1990 and 2005. Development work
continues to focus on the aim to ensure that each new model surpasses its
predecessor both in driving dynamics and in economy. In conjunction with BMW's
outstanding expertise in the field of engine development, this has led to the
production of vehicles which set new benchmarks in both areas within their
various competitive environments. The optimisation of fuel consumption and
exhaust emission levels is not only limited to special models but is a standard
component of the product substance in all new vehicles.

Increased output, lower fuel consumption - this principle applies to all model
series for the engine types newly introduced in the model year 2008. It is
implemented with new petrol and diesel engines as well as with a wide range of
engine measures which increase efficiency.

High Precision Injection for 6 and 4-cylinder engines:

In addition to the in-line 6-cylinder engines, BMW's 4-cylinder power units now
also have petrol direction injection in its second generation. The technology
is known as High Precision Injection and enables so-called lean combustion
operation across a broad engine speed range, resulting in significant
reductions in fuel consumption in everyday traffic. The highly precise and
efficient fuel injection is carried out by piezo injectors which are positioned
between the valves in the cylinder head and thus in immediate proximity to the
spark plug.

In the model year 2008, 4-cylinder engines with High Precision Injection in
lean combustion operation are used in the new BMW 520i, in all versions of the
BMW 3 Series and the BMW 1 Series. In addition to the two engines already
introduced with a capacity of 2.0 litres each, a new 1.6 litre petrol direct
injection engine in the new BMW 116i now also sees its premiere. As compared to
the predecessor engine in each case, the three new 4-cylinders have an output
which is has been increased by between 5 and 15 kW. Nonetheless, fuel
consumption in the models fitted with these engines drops by up to 23 per cent.

4-cylinder diesel with the latest common rail technology and now also with
Variable Twin Turbo:

In the model year 2008 , the new generation of 4-cylinder diesel engines is
also completed. The 2.0 litre lightweight construction aluminium units are now
available in up to three output levels for the BMW 5 Series, the BMW 3 Series
and the BMW 1 Series as well as the BMW X3. They are fitted with the latest
version of common rail injection, in which piezo injectors convey the fuel into
the combustion chambers - at a pressure of up to 2,000 bar for the first time.
The most powerful version of the new 4-cylinder diesel engine is presented in
the BMW 1 Series. It has a supercharging technology referred to as Variable
Twin Turbo which was already used in the BMW in-line 6-cylinder diesel engines.
This system consists of two turbochargers of different sizes. Due to is low
moment of inertia, the smaller of the two turbochargers develops its
performance-enhancing effect even at low engine speeds and without any
noticeable delay. As the engine speed increases, the larger turbocharger comes
into use. This combination ensures an impressive level of power delivery which
is unsurpassed in its spontaneity.

The new 4-cylinder in the BMW 123d delivers 150 kW/204 bhp and is thus the
world's first all-aluminium diesel engine with a power output per litre of over
100 bhp. Due to its extremely precise fuel dosage and the high level of
efficiency of its combustion process, it also achieves top figures in terms of
economy - just like the other two new diesel engines. The BMW 123d makes do
with 5.2 litres of diesel per 100 kilometres in the EU test cycle. Its CO2
level is 138 g per kilometre.

Even greater efficiency thanks to brake energy regeneration, Auto Start Stop
Function and needs-oriented control of ancillary units:

In addition to the design of engines which are optimised for reduced fuel
consumption and exhaust emissions, the development strategy BMW
EfficientDynamics also includes a wide range of other measures which contribute
to the increase of driving pleasure and economy in each new model. Among other
things, the focus here is on weight optimisation, reduction of road resistance
and the improvement of aerodynamics. Measurable progress towards favourable
fuel consumption levels can also be made by means of intelligent energy
management. In the model year 2008 there is a further increased number of
vehicles in which these measures have been applied. The combination of measures
to increase efficiency in the vehicle and within the engine environment is
specifically adapted to each model and engine type. The measures are thus not
limited to special models but are an integral part of every vehicle's standard
fittings.

In future, all models of the BMW 6 Series, BMW 5 Series, BMW 3 and BMW 1 Series
as well as the BMW X5 will be fitted with brake energy regeneration. It is the
result of intelligent energy flow management which leads to a more efficient
use of the energy contained in the fuel and increased dynamic performance on
acceleration manoeuvres. By means of brake energy regeneration, the generation
of electrical current for the vehicle power supply is focused on the vehicle's
trailing throttle and braking phases. During the pulling phases, however, the
generator is decoupled, providing more drive energy for conversion into driving
dynamics.

Auto Start Stop Function was presented for the first time in spring 2007 in the
new BMW 1 Series and in the BMW 320i Coupé/Convertible. In the model year 2008
enables a reduction of idling phases on interim stops at junctions or in
traffic jams in all other 4-cylinder versions of the BMW 3 Series. As soon as
the driver puts the gear lever into the neutral position and removes his foot
from the clutch, the engine is automatically switched off. As soon as further
travel is possible, it is sufficient to activate the clutch and the engine
starts without delay.

Other features for refining energy management in the vehicle include the
needs-oriented control of ancillary units, the use of electrical steering and a
Varioserv steering pump and the decoupling of the air conditioning compressor.
For example, needs-oriented control of the coolant pump uses significantly less
energy than conventional systems which run permanently at full capacity. The
servomotor of the electric steering is only activated when steering boost is
required or desired by the driver. With the Varioserv steering pump, the cam
ring is adjusted in relation to pressure and volumetric flow so as to avoid the
loss of drive train power as the engine speed increases. The power dissipation
of conventional air conditioning compressors can also be reduced by means of
intelligent regulation. In the new BMW models, the compressor is separated from
the belt drive by means of a magnetic coupling as soon as the air conditioning
system is out of operation.

These measures reduce the amount of electrical energy required, and as a result
the generator has to convert significantly less primary energy into electrical
current. A special low viscosity transmission oil contributes to the reduction
of frictional loss. What is more, optimised heat management for the rear-axle
drive ensures that frictional resistance is reduced more quickly after
starting. The reduction of aerodynamic resistance also supports the decrease of
fuel consumption. With cooling air flaps which open or close depending on the
driving situation and which are actively controlled in some models, the
aerodynamic properties of a vehicle can be further optimised.

The driver also receives support in the choice of the most economical driving
style from the gear shift indicator. This system uses data provided by the
engine control unit to calculate in each situation the most favourable point at
which to shift down or up from the point of view of economical fuel
consumption. The signal to change gear appears in the instrument panel. Here an
arrow symbol and a figure show which gear would be most suitable for economical
motoring.

BMW EfficientDynamics is a fixed element of every new BMW. The selection of
measures is tailored specifically to each model, however. The following list
shows which features are available in which models.

Brake Energy Regeneration: as standard in all models of the BMW 6 Series, BMW 5
Series, BMW 3 Series and BMW 1 Series as well as the BMW X5.

525d, BMW 520i, BMW 520d and in all models of the BMW 3 Series and BMW 1
Series, as well as BMW X3 (except X3 3.0sd) and BMW X5.

The new BMW 6 Series: with a diesel engine for the first time:

The new BMW 6 Series is stylishly assured in its appearance and progressive in
its technology in the model year 2008. With specific modifications to its
characteristic design, an interior which has been refined in selected details
and enhanced with new colour accentuations, innovations in the engine area and
driver assistance and safety systems, the new BMW 6 Series Coupé and the new
BMW 6 Series Convertible acquire an increased fascination. The most important
new feature under the engine compartment lid: for the first time in a vehicle
of this segment, a diesel engine delivers the pulling power and economy. As the
world's most powerful engine of its kind, the 3.0 litre in-line 6-cylinder
diesel with Variable Twin Turbo gives the BMW 6 Series its efficient dynamics
in an especially impressive manner. 210 kW/286 bhp and a maximum torque of 580
Nm makes for a sporty driving performance. The BMW 635d Coupé requires no more
than 6.3 seconds for acceleration from zero to 100 km/h, the Convertible does
the spurt in 6.6 seconds. The fuel consumption determined according to the EU
test cycle is 6.9 litres for the Coupé and 7.2 litres for the Convertible. The
resulting increase in range to 1,015 kilometres in the Coupé and 970 kilometres
in the Convertible is in keeping with the long-distance character of the model
- a traditional feature of Gran Turismo vehicles.

Increased efficiency is also a characteristic feature of the two other engine
types in the BMW 6 Series. The leader here is the 270 kW/367 bhp 8-cylinder
engine in the BMW 650i Coupé and BMW 650i Convertible, also fitted with
additional measures to reduce fuel consumption. With the introduction of a new
power unit for the BMW 630i, petrol direct injection now enters the BMW 6
Series, too. The new in-line 6-cylinder with High Precision Injection delivers
200 kW/272 bhp. It is thus 10 kW more powerful than its predecessor engine. The
new BMW 630i Coupé now manages the spurt from zero to 100 km/h in 6.2 seconds,
the Convertible takes 6.7 seconds. The fuel consumption of the BMW 630i as
determined by the EU test cycle is 7.9 litres per 100 kilometres for the Coupé
and 8.3 litres for the Convertible - as much as 15 per cent below the levels of
the predecessor models, which were themselves highly efficient.

The BMW 5 Series: greater variety, increased economy:

In the new BMW 5 Series, there are six petrol and four diesel engines to choose
from in the model year 2008. More than ever before, the Sedan and Touring
realise their aspiration to set benchmarks both in driving performance and
economy. The two new entry level versions of the BMW 5 Series - the BMW 520d
and the BMW 520i - show just what the development strategy of efficient
dynamics is capable of achieving in this vehicle category. The new BMW 520d is
powered by a newly developed 4-cylinder diesel engine whose output has been
increased over the predecessor engine by 10 kW to 130 kW/177 bhp. Both in the
Sedan and in the Touring model this results in a perceptibly higher level of
driving dynamics. For example, the Sedan now accelerates from zero to 100 km/h
in 8.3 seconds, the Touring in 8.5 seconds. At the same time, fuel consumption
in the two models is reduced by around 14 per cent. Like the Sedan, the new BMW
520d Touring also achieves outstanding levels within its segment, with an
average fuel consumption 5.3 litres per 100 kilometres in the EU test cycle and
a CO2 output of 140 g per kilometre.

The BMW 520i performs a similar role model function in the petrol engine
domain. Its 125 kW/170 bhp 4-cylinder power unit with High Precision Injection
provides driving fun which is reflected in acceleration rates of 8.7 (Sedan)
and 9.0 seconds (Touring) for the spurt to 100 km/h. The efficiency-enhancing
qualities of the new engine are equally clearly demonstrated: for the new BMW
520i, the EU test cycle gives an average fuel consumption of 6.7 litres per 100
kilometres (Touring: 6.9 litres) and a CO2 level of 162 g per kilometre
(Touring: 166 g). Both in the BMW 520d and the BMW 520i, BMW realises a level
of efficiency which is still exceptional even in the smaller vehicle categories.

The BMW 3 Series: more dynamic, more efficient - the lead increases:

The BMW 3 Series consolidates its status as the sportiest and at the same time
most progressive car in the segment in the model year 2008 with the
introduction of new engine variations which are both powerful and economical.
Efficient dynamics once again characterises the extension of the model range in
this model series. New 6-cylinder and 4-cylinder petrol engines with the direct
injection system High Precision Injection in lean combustion operation and the
new 4-cylinder diesel engines with common rail injection of the third
generation are now available for the Sedan, the Touring model, the Coupé and
the Convertible of the BMW 3 Series.

Six petrol engines, five diesel power units - never before has the engine range
of the BMW 3 Series been so large. Along with this variety, the lead of the BMW
3 Series over competitors also continues to increase when it comes to the ideal
relation between driving dynamics and economy. For the first time, all petrol
engines - both the 6 and the 4-cylinder units - are fitted with the direct
injection system known as High Precision Injection. The spectrum now ranges
from the BMW 118i to the 3.0 litre in-line 6-cylinder in the BMW 335i, whose
combination of High Precision Injection and Twin Turbo takes it up to an output
level of 225 kW/306 bhp.

Within the BMW 3 Series alone there are now five models to choose from whose
CO2 level in the EU test cycle is no more than 140 g per kilometre. The front
runner in terms of efficiency and emissions among the diesel models is the new
BMW 318d. Its 105 kW/143 bhp 4-cylinder diesel engine with common rail
injection of the third generation allows both the Sedan (4.7 litres/100
kilometre, 123 g CO2/km) and the Touring model (4.8 litres/100 kilometre, 125 g
CO2/km) to achieve levels of fuel consumption and exhaust emission levels which
are unbeatably low.

The BMW 1 Series: premiere for new engines:

In the model year 2008, the BMW 1 Series is extended to include a fascinating
body variation. There are three new BMW 1 Series engines which celebrate their
premiere in the model year 2008. For the first time in the model year 2008, the
new 4-cylinder diesel engine with Variable Twin Turbo is available both for the
5 and 3-door models. The 150 kW/204 bhp power unit gives the BMW 123d a unique
status in a number of disciplines. The new model has a particular fascination
due to its degree of pulling power, which is unique within its segment, and it
also has outstanding fuel consumption levels. The 5-door and 3-door models make
do with 5.2 litres of diesel for 100 kilometres in the EU test cycle. The CO2
level of the BMW 123d is 138 g per kilometre.

With these figures, the new BMW 123d symbolises the spirit and also the
potential of the development strategy BMW EfficientDynamics in a particularly
striking manner. Its engine is the world's first all-aluminium diesel power
unit to deliver an output of over 100 bhp. At the same time, the BMW 123d is
the first large-series vehicle over 200 bhp whose CO2 output is below the 140 g
level.

The BMW X5: outstanding qualities - in the area of efficiency too:

With superior driving dynamics, a powerfully expressive design, a luxurious
ambience and great interior versatility, the new BMW X5 continues to
consolidate its leading position within its segment. With an extended selection
of engines, the successful Sports Activity Vehicle (SAV) raises the benchmark
once more in terms of efficiency in the model year 2008. Supremacy in
particularly economical form is embodied most clearly by the new BMW X5 3.0sd,
which is powered by a 3.0 litre in-line 6-cylinder diesel engine with Variable
Twin Turbo. 210 kW/286 bhp and a maximum torque of 580 Nm enable an
acceleration of zero to 100 km/h in just 7.0 seconds. 8.2 litres per 100
kilometres is the average fuel consumption according to the EU cycle. This
gives the new BMW X5 3.0sd a maximum range of 1,035 kilometres - a
long-distance capacity which is outstanding within the segment.

Other model variations of the BMW X5 also have extensive measures to optimise
fuel consumption and exhaust emissions, including brake energy regeneration and
needs-oriented control of the ancillary units. In the top model of the series,
the BMW X5 4.8i powered by a 261 kW/355 bhp 8-cylinder engine, the average fuel
consumption is reduced by 4 per cent to 12.0 litres per 100 kilometres
according to the EU test cycle. The BMW X5 3.0si manages 10.2 litres - a
reduction of 6 per cent - and the average fuel consumption of the BMW X5 3.0d
is now 8.1 litres per 100 kilometres, a reduction of 7 per cent as compared to
the level achieved in model year 2007. The BMW X3 2.0d is now also available
with the new, quick-shifting six-speed automatic transmission.

The BMW X3: number one in the segment in terms of dynamic performance and
economy:

Versatile, agile and high-quality like no other vehicle in its segment: the BMW
X3 is consistently on course for success once again in the model year 2008. In
addition, the Sports Activity Vehicle also sets new standards in the field of
economy. Six state-of-the-art petrol and diesel engines are available.

The leader of the segment in terms of efficiency will be the new BMW X3 2.0d.
Its all-aluminium 4-cylinder diesel engine delivers 130 kW/177 bhp and
mobilises a maximum torque of 350 Nm. With an average fuel consumption based on
the EU test cycle of 6.5 litres per 100 kilometres and a CO2 level of 172 g
per kilometre, the new BMW X3 2.0d achieves the best levels in its vehicle
category in the model year 2008.

BMW EfficientDynamics enables leading position in all segments:

The engines and model variations launched in the model year 2008 secure a
leading position in terms of efficiency in all the relevant segments for BMW.
This is the result of the development strategy BMW EfficientDynamics, which has
been pursued by the BMW Group for many years in engine development and today
already provides an impressive response to the demands of the future in terms
of fuel consumption and exhaust emission levels. The result: dynamic vehicles
with significantly reduced fuel consumption and CO2 levels as compared to the
predecessor models in each case.

The leading position occupied by the new BMW models within their competitive
field does not arise from a short-term shift of priorities but is based on a
fundamental and long-term orientation of development work. In the new models,
technological developments are used which were decided as part of the BMW
EfficientDynamics strategy some five years ago and which have now reached a
state of readiness for serial production. As a result, not only the highly
efficient petrol and diesel engines but also extensive measures for the
reduction of fuel consumption and exhaust emissions are now available to a
large number of new models. Thus the highly effective package to increase
efficiency is not limited to individual special models or niches but forms an
integral part of the standard fittings of all new BMW models.
