Like its predecessor - the legendary 1985 M635CSi – the new M6 resets the sports GT benchmark, with supercar performance, dispatching the zero to 62mph sprint in 4.6 seconds and achieving a limited top speed of 155mph. If derestricted, the M6 would be capable of a 200mph+ top speed. During tests at the famous Nürburgring Nordschleife circuit, the new M6 regularly clocked eight minutes lap times. These rarefied performance statistics are, however, backed up by ‘real world’ economy and efficiency - the new M6 delivers a combined EU fuel consumption of 19.0mpg and a CO2 rating of 357g/km.
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 240kg.
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.
