THE new BMW M6 coupé and M6 convertible are equipped with the same high-revving, turbocharged V8 engine as the M5 saloon.

The key to this impressive performance is BMW's M TwinPower turbo technology.

This revolutionary 4.4-litre power plant not only produces 53hp more than its 10-cylinder predecessor at 560hp, but also benefits from a greatly improved torque output over a broad band of revs. It delivers 680Nm of torque from as low as 1,500rpm, not only giving the new M6 stunning outright acceleration but also making it very flexible. BMW quotes rest to 62mph acceleration in just 4.2 seconds in the case of the M6 coupé.

The adoption of BMW's EfficientDynamics technology helps reduce consumption and emissions by approximately 30% with fuel economy also improved. The new M6 coupé has a combined fuel consumption of 28.5mpg (convertible 27.4mpg) with CO2 emissions of 232g/km (convertible 239g/km).

The new coupé and convertible will go on sale in the UK in September costing £93,795 and £98,995 respectively.
