BMW TWIN POWER TURBO ENGINES.Powered by efficiency and driving pleasure.
The multiple award-winning petrol and diesel engines with BMW TwinPower Turbo technology are among the
innovations from BMW EfficientDynamics. They combine the latest fuel injection systems,
fully-variable performance control and innovative turbocharger technology.
BMW TwinPower Turbo petrol engines.
Three components ensure that the BMW TwinPower Turbo petrol engines are capable of achieving the unique relationship between performance and consumption.
The innovative valve control Valvetronic (= variable valve and electronic) with Double-Vanos varies the hub of the inlet valve fully.
This allows the engine to develop optimum power with less consumption. The Valvetronic also improves the mixture preparation and lowers fuel consumption by up to 10%
(BMW internally-determined value based on ECE driving cycle). An additional effect is improved response.
Double-Vanos refers to the double variable camshaft control. This system controls the engine performance all across the speed range and enables lower consumption and fewer emissions at any speed.
High Precision Injection with its particularly accurate fuel dosage ensures extraordinarily efficient and clean combustion. This derives the maximum amount of energy from every drop of fuel.
Innovative turbocharging technology increases the engine’s power and puts it on par with much larger engines – and all this with fewer components, reduced inner friction and low weight.
And thus with lower consumption and emissions.
Together with the other innovations by BMW EfficientDynamics this allowed a fuel saving of up to 15%, for example, in the BMW 328i Sedan in relation to its predecessor the BMW 325i.
BMW TwinPower Turbo diesel engines.
The consistent implementation of BMW EfficientDynamics ideas is again evident in the BMW TwinPower Turbo diesel engines.
They are made in lightweight aluminium construction and use variable turbine geometry, which permits a more efficient use of exhaust heat energy. This results in the turbo engine performing like a much larger
aspirated engine and achieving this special performance with lowered consumption.
The common rail injection system guarantees optimum combustion. An important characteristic of this system is that the injection pressure can be created autonomously of the speed of the engine and the amount injected.
Combined with a powerful control unit and injection nozzles, this markedly reduces consumption and emissions and increases running smoothness.
A fully-variable performance control and the unique turbocharging technology round off the innovation package with less space and weight. In total,
these diesel engines offer typical BMW torque with low consumption – a unique combination of efficiency and dynamics.

Fuel consumption / CO2 emissions
Figures for BMW M 550d xDrive
Fuel consumption
Combined: 6.3 l/100 km
Urban: 7.1 l/100 km
Extra-urban: 5.8 l/100 km
CO2 emissions combined: 165 g/km
The figures for fuel consumption and CO2 emissions depend on the wheel and tyre sizes selected.
Further information about the official fuel consumption and the official specific CO2 emissions for new passenger automobiles can be found in the 'New Passenger Vehicle Fuel Consumption and CO2 Emission Guidelines', which are available free of charge at all sales outlets and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, 73760 Ostfildern, Germany.
