Coinciding with the 75th anniversary celebrations of BMW Automobiles, the
company is once again making its mark in history through engine technology -
its core competence. Featuring revolutionary inline six power units, BMW is
simultaneously opening several new chapters in engine manufacture. Featuring a
lightweight construction and numerous innovations, the new BMW 3.0 litre
internal combustion engine with a composite magnesium/ aluminium crankcase and
VALVETRONIC sets standards in trendsetting engine technology. The new 3.0 litre
turbo diesel engine featuring Variable Twin Turbo technology will undoubtedly
take a front seat in the first row of BMW high-performance power units.

BMW engines enter a new era

The BMW Group enters new dimensions:
"We will keep our foot on the accelerator pedal, we will continue to forge
ahead." ith these words Dr. Helmut Panke, chief executive of the BMW AG,
proclaimed at this year's Annual Accounts Press Conference in which direction
the Bavarian premium manufacturer is moving - 'straight ahead', as usual. New
series, new models and the opening up of new markets - BMW has impressively
underlined over recent years that when it comes to the brand with the white and
blue badge, actions speak louder than words. In 2003, BMW achieved the highest
sales figures ever, the number of vehicles sold reaching 928,151.

The inline six-cylinder engine.
When speaking of acceleration, Dr. Panke is not referring to just a short
spurt, but "the lasting accomplishment of a higher speed". In aspiring to do
this,
a premium manufacturer requires the appropriate premium engines. Superior
technology has rendered BMW the leading producer of power units. BMW regularly
receives the annual'International Engine of the World Award', BMW has initiated
advancements in engineers' construction with the introduction of innovations
such as VANOS and VALVETRONIC, successfully establishing them on the market.

For 71 years now the inline six engine has served as a basis of driving
pleasure. And there is no reason to break with this tradition, a tradition that
is probably unique in the field of engine construction. This is due above all
to the fact that it is based on a proven physical principle (no free inertia
forces and moments). Today more than half of all BMW automobiles are powered by
either an inline six petrol engine or a diesel engine. Consequently, BMW is the
world's largest manufacturer of inline six power units for automobiles.

Optimum balance of masses, silky-smooth turbine-like running characteristics,
fast-revving - ideal genes, pioneering innovations, high performance, low fuel
consumption and the engineers' constant meticulous attention to detail have
optimized the BMW inline six engine and rendered it an icon. The principle of
consistent innovation to raise its own standards has placed BMW in a pole
position in technology, not only in the field of engine construction, but also
as a carmaker as a whole.

The concept of efficient dynamics.
he BMW designers' main conflict of objectives arises from the customer's desire
for more power, comfort and safety on the one hand and from the equally
understandable desire for lower fuel consumption and reduced exhaust emission
on the other: BMW subsumes this issue under the term efficient dynamics, and
understands this as being considerably more than the mere improvement of a few
test values. Consequently, BMW interprets the term dynamics as the general
behaviour of the vehicle, as its performance offered to the customer as a part
of the driving experience. Efficiency is equally as comprehensive, this being
the overall ratio between input and output, including, for example, 'on demand'
and 'just in time' production, as well as the sensible use of resources. It is
particularly crucial to BMW that efficiency should not belittle dynamics - and
vice versa.

Technology leader BMW forges ahead: engine construction reconceived.
Due to its specific location in the vehicle and its concentrated mass, BMW
designers focus predominantly on the power unit when it comes to discussing
efficient dynamics, weight and the distribution of weight in the vehicle within
the framework of the concept. And this is precisely the point at which emotions
are sparked among engineers, as the BMW power unit is not only a splendid
example of technology, but also a matter of inner attitude. Hence the new
challenges were taken up passionately. This resulted in the creation of typical
BMW high-tech power units that fundamentally question previously known concepts
and countless details - and respond with innovative, trendsetting solutions.

In the 75th year of the BMW automobile and 71 years after the first BMW inline
six engine, BMW is taking a giant and fundamental step into the future of
engine construction. BMW has radically reconceived both the internal combustion
engine and the diesel engine, taking the BMW inline six power unit into a new
era.
