Engine & Chassis
Powered by the same 4,999cc engine that set new standards in the M5, the 507bhp power output ensures that the new M6 maintains the M car tradition of breaking the 100bhp per litre benchmark. Peak power is developed at 7,750rpm with the red line set at 8,250rpm. Peak torque of 520Nm is developed at 6,100rpm of which 450Nm is available from just 3,500rpm. The 90-degree V10 aluminium-silicon alloy engine block is extremely light yet robust and is the first V-arrangement engine to use a bedplate construction. The aluminium bedplate with cast-iron inlays ensures the engine's rigidity throughout the rev range, but the complete unit still weighs just 240kgs.

The capable chassis of the new M6 permits lateral acceleration in excess of 1g. To cope with such forces, the V10 engine features a lateral force-controlled oil supply that, from 0.6g of lateral movement, activates one of two electronic oil pumps to draw oil from the cylinder head and delivers it back into the sump to ensure perfect lubrication even in the most extreme situations. It is because of the extreme forces that can be induced by the M6 that the car also makes use of a semi dry sump lubrication system with an oil reservoir on each side of the front subframe.

Masterminding all the M6's engine electronics is one of the most advanced engine control systems ever developed. The MS S65 control unit coordinates all engine functions using three 32-bit processors that handle more than 200 million operations per second from over 50 incoming signals. Each of the 10 cylinders has its own throttle butterfly, with its position being monitored 200 times per second. Reacting to changes in throttle position, the butterfly can move from closed to fully open in a mere 120 milliseconds (approximately three times faster than the blink of an eye).
