More power per litre: the BMW diesel power trains are just one example of how our engines are continually improved as part of BMW EfficientDynamics. The engine block of the four- and six-cylinder variants is made of aluminium and has optimized combustion chamber geometry. The third-generation common rail injection system works with an extremely high injection pressure of up to 2,000 bar, now firing the fuel into the combustion chamber with high-precision switching piezo injectors. It's the sum of these technologies that makes the crucial difference: markedly reduced CO2 emissions combined with increased performance.

Fuel consumption / CO2 emissions

Fuel consumption urban: 3.3 to 10.5 l/100 km
Fuel consumption extra-urban: 3.9 to 7.1 l/100 km
Combined fuel consumption: 4.4 to 8.3 l/100 km
Combined CO2 emissions: 118 to 220 g/km

Further information about the official fuel consumption and the official specific CO2 emissions for new passenger automobiles can be obtained from "The Passenger Car (Fuel Consumption and CO2 Emissions Information) Regulations", which are available free of charge at all sales outlets and at DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, 73760 Ostfildern, Germany.
