BMW Unveils M6 Grand Coupe with 560 HP [Photo Gallery]
The M6 Gran Coupe’s biggest attraction is the engine under the bonnet. It’s the same 4.4-liter twin-turbocharged V8, borrowed from the X5 M and updated to the later S63Tü spec for the M5 and M6. It makes 560 PS (553 HP) and also produces 680Nm (501 lb-ft).
Despite having a little extra weight to carry around, the M6 with four doors still gets from 0 to 100 km/h in 4.2 seconds, which is the same as the M6 coupe and faster than the M5 saloon. Top speed is limited to just 50km/h (155mph), but can be increased to 305km/h (189mph) with optional M Driver’s package for a bit of extra cash.
