Ladies and Gentlemen –
I would also like to welcome you here at our press conference in Geneva.
Very few automobile manufacturers place such an emphasis on engine production as the BMW Group does. It is all in the name: BMW stands for “Bayerische Motoren Werke“ or in English: “Bavarian Engine Plants”. So the core of our brand name is at the same time a BMW brand’s core competence: the development and production of engines.


Starting with the first BMW aircraft engines, BMW engineers managed to set height and distance records – a mere two years after the company was founded in 1916. Later, other vehicles caused sensations: first the BMW motorcycles – think about Ernst Henne’s 1937 speed record – and from the 1930s on cars as well.
Innovative, high-performance engines – this is what we are famous for. These engines are an important part of our history.
As BMW has long dealt with engine production, an amazingly varied range of different engines has been developed: just think about our 4, 6, 8, 10 or 12-cylinder engines. We always offer our customers the ideal engine for their vehicle. All our engines guarantee “the ultimate driving machine” and “sheer driving pleasure”. And of course, they all are known for efficient dynamics.
A modern day’s BMW engine has to meet three characteristics – namely
• sporting flair
• low weight and
• high efficiency.


This is the basic principle behind the entire range of BMW engines we are presenting here at our stand at the Geneva Motor Show. We are also showing some powertrain concepts, which are about ready to go into series production as well as some winners of recent engine contests.
I would like to give you some examples to demonstrate how we combine sporting flair and efficiency.
Among the varied range of BMW engines, the in-line six-cylinder engine occupies a special position. After all, close to 600,000 vehicles or more than 53 per cent of all BMW vehicles sold in 2005 sport an in-line six-cylinder engine.
Mounting our six-cylinder engines in-line clearly distinguishes us from competitors. And we have good reason for our special approach: Among six-cylinder engines, the in-line engine is clearly the one that runs most smoothly and that vibrates the least. It also has the highest potential for reducing fuel consumption and for charging processes. This can only be done thanks to the “hot and cold side” of this engine principle, which only exists in in-line engines – and at BMW, that is our six-cylinder. This clever and sophisticated powertrain concept has proved its worth since 1923 – so for over 70 years – when it was first mounted in a BMW vehicle. And there is still more potential to be tapped.

A prime example for efficiency and dynamics among our engines is the 3-litre 265 horsepower six-cylinder in-line naturally aspirated engine. Its advanced performance characteristics and reduced fuel consumption result from an enhanced combustion process and the VALVETRONIC charge cycle. Moreover, this engine is the most light-weight in its class.
For the first time, a crankcase has been made from a combination of magnesium shell and aluminum insert. Weight is further reduced by the cylinder head cover and the bedplate, both made from magnesium, as well as the light-weight camshaft. The fully-variable valve control VALVETRONIC, the double-variable camshaft control on the intake and outlet side – called “BIVANOS“ at BMW –, the electrical coolant pump as well as the controlled oil pump help to reduce fuel consumption by 10 per cent according to the EU test cycle. This engine is a sensation in that it has overturned the traditional interrelation between consumption and performance.
Our latest example is the new in-line biturbo six-cylinder engine, which is making its debut here at Geneva. It truly stands for maximum sporting flair. The innovative powertrain with the direct injection system “High Precision Injection” offers maximum performance at 306 horsepower and a torque of up to 400 Nm. There is probably no other engine on the market – at least not in this performance class – which is as light-weight and compact as our new turbo engine.
Over the course of the 100-year turbo history, BMW has again and again set milestones in development. In Europe, turbo technology found its way into series production in 1973 when BMW built the BMW 2002 Turbo. BMW had already been the first manufacturer to apply turbo engines to touring car racing in the late 1960s. A BMW Brabham was the first turbo vehicle to win a Formula One world championship. This was in 1983 when the top podium position went to Brazilian Nelson Piquet.
As you can see, our company has a longstanding and successful tradition in turbo technology. But as for a long time turbo was linked directly to a considerable increase in fuel consumption, we had deliberately decided to set this technology aside for a while. This seemed reasonable considering rising fuel prices and a sensible use of resources. But now, thanks to the distinctive features of the in-line biturbo six-cylinder engine – the direct injection system “High Precision Injection“, BIVANOS as well as the innovative and heat-resistant materials from space technology used for the turbo charger – supercharging is again meeting the BMW requirements.
This engine comprises two small turbo chargers, which allow for an excellent response behavior. The typical “turbo lag” – the moment right before the charger kicks in to enhance performance – has now become a thing of the past. This engine is agile, and it performs like a big naturally aspirated engine, but at much better mileage.
All the elements I have just mentioned make the six-cylinder in-line biturbo engine the perfect embodiment of maximum dynamics and maximum efficiency.
“High Precision Injection” and BIVANOS optimize combustion, thus guaranteeing great performance at low fuel consumption. Our supercharged in-line six-cylinder engine attests to the efficiency of the basic concept behind our outstanding and award-winning in-line six-cylinder engine. In two months, we will announce a first vehicle to sport this new engine generation. It will be launched on the market in the foreseeable future.
”High Precision Injection” is also the basic technology that makes the BMW Group one of the first manufacturers to promote the second generation lean-burn direct injection. Piezo fuel injectors guarantee a highly efficient, spray-guided combustion of lean air-fuel mixtures.
And our customers stand to benefit from a further reduction in fuel consumption. We have given you the first idea about that we presented our showcase, the X3 Efficient Dynamic powertrain.
Ladies and Gentlemen –
When we talk about catchphrases such as “efficiency” and “low fuel consumption”, we definitely have to talk about diesel technology as well. Thanks to their great mileage and the impressive driving characteristics, diesel vehicles are on the upswing all across Europe.
And fortunately, major progress has just recently been made in matters of exhaust treatment, thanks to – among other things – diesel particle filters. These advances will further the acceptance of diesel technology also in the USA. There it is vital to rise to the challenge of the NOx limit values. It is mainly an accomplishment of the German automotive industry that diesel emissions are decreasing considerably in the USA. But we should not forget that technologies, which are currently available, are nothing but interim solutions. If the BMW Group is to enter the American market with a diesel product, it will be with one that offers a truly sustainable solution such as the exhaust treatment by SCR technology – which is the drastic reduction of NOx content by use of urea. Those SCR catalytic converters dramatically lower NOx content and – in cooperation with the particle filter – reduce exhaust emissions to a minimum. However, we still have quite some way to go before this trend-setting technology will be fully developed.
This is something BMW’s traditional diesel-powered in-line six-cylinder engines have already demonstrated: Since the launch of the very first one in the 1980s, our diesel engines have again and again been ahead of competition in terms of performance and sporting flair. The extraordinary potential that particularly the diesel in-line six-cylinder engine offers was demonstrated two years ago when we introduced the Variable Twin Turbo technology. Such a high power density would not have been feasible with any other engine type. Right now, we are still the only manufacturer applying this technology, and we are soon going to implement it into other model series.
Future diesel engines of the BMW brand will also be based on the in-line six-cylinder engine. It allows the application of our groundbreaking Variable Twin Turbo technology in combination with concepts to reduce emissions in a most compact way.
Ladies and Gentlemen –
You see: In-line six-cylinder engines are a crucial element of the BMW product mix.
So it is almost a matter of course that the Z4 M coupe we are presenting today sports an in-line six-cylinder engine as well. With its award-winning 3.2-liter M engine and 343 horsepower, it is a true showcase in terms of dynamics, driving pleasure and sporting flair.
This sports car has a powerful chassis; its zero-to-hundred time is a mere 5 seconds, with a top speed of 250 kilometers per hour. The BMW Z4 M coupe is a sports car for the very special moments in life. Uncompromising, puristic and extremely powerful. No matter whether you drive it in regular traffic or on the race track – this car gives you a one-of-a-kind experience of pure dynamics.
But now, ladies and gentlemen, it is time to present this unique sports car:
The BMW Z4 M coupe, now in a world premiere here at Geneva.
