BMW has achieved supercar levels of performance with its new 552bhp M6 coupé and convertible. The two are BMW’s fastest ever two-door road cars, with a top speed of nearly 305kph. They’re powered by a twin-turbocharged 4.4-litre V8. The new M6 coupe will debut at next-month’s Geneva motor show and the cabriolet will be revealed at the New York motor show in April this year.
The latest M6 coupé and convertible are closely related to the recently introduced M5 saloon, sharing its potent twin-turbocharged 4.4-litre V8 petrol engine and seven-speed, dual-clutch gearbox. With 552bhp and 69.4kgm of torque, the engine develops 52bhp and 16.8kgm of torque more than the naturally aspirated 5.0-litre V10 of the previous-generation M6.
It has sufficient reserves, says BMW, to compensate for the increase in kerb weight to 1850kg (the previous M6 coupé weighed 1710kg) and to propel the fixed-head car from a standstill to 100kph in 4.2sec and to 200kph in 12.6sec
Drive is channelled to the rear wheels via M division’s active differential, as on the M5. In standard form, the M6 reaches a top speed limited to 250kph — or 305kph with the optional M Driver’s Package.
The performance of the new 1980kg M6 convertible (50kg heavier than before) is no less impressive. It posts official times of 4.3sec for 0-100kph and 13.1sec for 0-200kph, together with the same top speed as the coupé.
