Innovation in detail for EfficientDynamics of the highest standard: Reduction of fuel consumption and emissions in BMW's new four-cylinder models. 28

Like the changeover to a new model, the presentation of a new generation of
engines by BMW always creates particular expectations. Clearly, newly developed
drive units are intended to offer significant improvements in as many areas as
possible.
BMW now once again defines this progress in very clear and specific terms,
presenting EfficientDynamics as the overriding philosophy behind precisely
those qualities which enhance sheer driving pleasure while at the same time
reducing fuel consumption and thus also optimising the car's emissions. Hence,
every new power unit is lighter, more powerful and at the same time more
fuel-efficient than its respective predecessor.

BMW's leadership in technology and engine construction acknowledged the world
over is based, not least, on the ability to consistently overcome the conflict
of interests between growing dynamics, on the one hand, and optimised economy,
on the other, in all vehicle and drive segments. This is clearly proven by the
newly developed power units BMW is launching at the 2007 Innovation Day - clear
and impressive proof of EfficientDynamics.

Offering precisely these benefits, BMW's new four-cylinder power units ensure a
new dimension of all-round economy - and at the same time enable the motorist
to enjoy the sheer driving pleasure so typical of a BMW in every respect.
