These are the latest spy pictures of the new BMW M6 GranCoupe testing at the Nurburgring. The new high-performance version of BMW’s luxury new four-door swoopy saloon will give BMW a rival to the potent Mercedes CLS63 AMG.
Power for the new M6 GranCoupe will come from the twin-turbo 4.4-litre V8 in the exact same specification as found in the new BMW M5. That means 552bhp and 501lb ft channeled to the rear wheels through a seven-speed dual clutch gearbox. The car should be good for 0-62mph in less than 4.5sec and a top speed limited to 155mph.
The M6 GranCoupe’s rival, the CLS63 AMG, uses a twin-turbo 5.5-litre V8. It has more power than the BMW’s latest charger with 518bhp, while torque is also slightly higher at 516lb ft.
The new M6 GranCoupe will essentially be a lower, even more focused version of the new M5. The roofline is lower than the M5 and the GranCoupe has a more slippery silhouette than its standard four-door sibling. A lower centre of gravity should also make it an even greater dynamic proposition than M’s staple saloon.
The spy pictures reveal a predictably muscular exterior for the GranCoupe. It gets the trademark M quad exhausts and large black twin five spoke alloys that hide what’s believed to be carbon ceramic brake discs.
The styling will also be much more aggressive than the handsome 6-series GranCoupe donor car, featuring the M body kit that includes a new front bumper, wider sills and a rear diffuser.
The new 6-series GranCoupe is still around four months away from its showroom debut. The M6 version is tipped to be launched in 2013. It will be beaten to market by the two-door M6, which will be revealed this year.
