BMW 3 Series - the milestones (1)

Munich. In the year 2008, the BMW Series engine range is presenting itself as
more diverse and efficient than ever before in its 33-year history. There is a
choice of five petrol and diesel engines for both the Saloon and the Touring
model. The performance spectrum ranges from 105 kW/143 bhp for the BMW 318i and
the BMW 318d to 225 kW/306 bhp for the 335i.

The most significant commonality of all featured power units is the
exceptionally favourable balance between performance and fuel consumption. All
models in the BMW 3 Series have better fuel economy and emission levels than
their immediate rivals in each of their respective performance classes - and
some of them even considerably better driving dynamics.

33 years of efficient dynamics.

Efficiency and dynamics - these two characteristics have been the hallmarks of
the BMW 3 Series for 33 years now. Even the first generation of the medium
class saloon managed to spark enthusiasm with a sporty performance untypical of
its segment in those days and at the same time convinced with exceedingly high
fuel economy. Today the BMW 3 Series owes its exceptional position
predominantly to the current BMW EfficientDynamics measures which are standard
features on all models.

Engines with an exceptionally high degree of efficiency, intelligent energy
management inside the vehicle, lightweight construction and optimised
aerodynamics are the result of a development strategy to achieve better driving
dynamics coupled with a reduction in fuel consumption. BMW engine designers
have considered themselves bound to this principle for some time now.

It is precisely for this reason that the success story of the BMW 3 Series from
1975 to this day has been influenced by numerous innovations from which both
performance and fuel economy have profited. One example above all clearly
demonstrates how fast drivetrain engineering has developed and how significant
these changes have become over period of time: Whilst a BMW 324d of the year
1985 with an output of 63 kW/86 bhp had a fuel consumption of 6.9 litres of
diesel over a distance of 100 km on an EU average, the latest top of the range
3 Series diesel model, the BMW 335d with a precisely 200 bhp higher output,
today even burns 0.2 litres less diesel over the same distance!
