Abstract
In 2004, BMW offered a two-stage turbocharging for the first time in the private car segment in the 3.0 l six-cylinder diesel engine. To continue this successful concept, the next generation of regulated, two-stage turbocharging was developed on the basis of the new 3.0 l six-cylinder in-line diesel engine available since 2008. This innovation enabled the core properties such as high performance, a wide usable speed band and low specific consumption to be further improved. With the new powertrain in the 740d, the fuel consumption has been reduced by more than 20 % compared to the most powerful eight-cylinder diesel version of the previous model while at the same time improving the driving performance and dynamics.
