Introduction
The S85B50 is the first BMW 10-cylinder petrol engine to be used in a production vehicle.
The power output is 507 HP (373 kW) with a cylinder capacity of 5 litres. The maximum torque is around
520 Nm.
The V10 engine, with a speed range of up to 8250 rpm, guarantees exceptionally high dynamics. The lightweight
construction of this engine means that it achieves a power/weight ratio of only 3.5 kg/HP (relative to an unladen
weight of 1755 kg).
In terms of dynamics therefore, it is comparable with a sports car.
The design of the engine and the engine electronics have their origins in Formula 1.
The most important innovations in the S85B50 are:
-
Ionic current measurement for the knock control and misfire detection
-
Torque feedback control operation using electrically-activated individual throttle butterflies
-
Oil supply with 4 oil pumps to cater for all driving situations
-
Demand-oriented fuel delivery with variable fuel pressure
-
Double VANOS with approximately 70 bar high pressure for rapid camshaft adjustment
-
Cooling according to the crossflow principle with split radiator
-
Engine output selectable in 2 stages with "POWER button"
