BMW officially announces new N54 Turbo Engine}0}

BMW finaly released new details on its much-rumored N54 Bi-Turbo Engine. The motor is expected to appear in the 2007 BMW 335i and 2007 BMW 335ci (coupe). The engine has an output of 306 horsepower and maximum torque of 295 lbs.-ft (400 Nm). BMW said it has already tested a 3-Series sedan with the engine, and achieved a 0-62mph time of 5.7 seconds. BMW said the engine is relatively lightweight — about 70kg less than its 4.0-liter V8 engine. According to the automaker, the 3.0-liter engine has little or no turbo lag, thanks to two small turbos instead of one large one. Maximum torque is achieved between 1500 and 5800 rpm.

The new top-of-the-range power unit featuring biturbo technology and direct gasoline injection will mark the highlight of BMW’s six-cylin­der engine family in future. Developing maximum output of 225 kW/306 hp and peak torque of 400 Newton-metres or 295 lb-ft, this highly innovative new engine fulfils the greatest demands also in terms of spontaneous and superior power. As the first straight-six with biturbo technology, high-precision fuel injection and an all-aluminium crankcase, this new highlight in engine technology offers a standard of responsiveness never seen before with a turbocharged engine as well as superior torque and pulling force all the way to the engine’s highest speeds. And at the same time this new turbo­charged power unit comes with the supreme smoothness and refine­ment so characteristic of BMW’s straight-six engines.
The particular efficiency and all-round economy combined with this supreme output and performance is attributable to BMW’s high-pre­cision fuel injection, the latest generation of direct gasoline injection by BMW making a significant contribution to the all-round economy of this trendsetting engine.
So now, introducing this combination, BMW’s engineers are writing a new and particularly attractive chap­ter in the history of turbocharged power units 100 years after the in­vention of the turbocharged engine.

BMW – the first turbocharged world champion in the history of Formula 1.}0}

Throughout 100 years of turbocharger history, BMW has set impor­tant milestones time and again: As early as in the late 1960s BMW became the first manufacturer to use turbocharged engines in touring car racing.
And in 1983 a BMW Brabham driven by Brazilian racing driver Nelson Piquet became the first turbocharged F1 to win the Formula 1 World Championship, BMW’s engine specialists succeed­ing even back then to extract far more than 1,000 horsepower from an engine displacing just 1.5 litres. Ultimately, however, it was precisely this almost unlimited option to boost engine output by means of tur­bo­charger technology which led to the decision in the highest realms of motorsport not to boost engine power any further.
In series production, on the other hand, all turbocharger concepts used so far have always had the unpleasant side-effect of increased fuel consumption – and indeed, this conflict of interests appeared insurmountable for a long time. Only the latest developments in engine technology have opened up the door to the new approach BMW is now following consistently, combining turbocharger tech­nology with high-precision fuel injection as the ideal concept for efficient dynamics in particularly fascinating style.
Now the new high-performance power unit marking the pinnacle of BMW’s straight-six engines impressively proves the fascinating po­tential of this concept and its most important components. With its superior responsiveness and equally outstanding pulling force, the new engine soon reaching the standard for series production opens up brand-new dimensions in driving dynamics.
Indeed, BMW’s engine development specialists even have further options and concepts in view for this engine and its technology: Over and above the drivetrain conceived and built for supreme dynamics, this technology provides the starting point for a lean-burn direct in­jection concept and thus serves to successfully optimise fuel con­sumption also in other performance classes. In this way BMW is once again proving its competence in engine construction, developing modern, up-to-date drive concepts and at the same time enhancing that sheer driving pleasure of BMW to an even higher standard.
