Car and Driver compares three of the best performing luxury 'coupe' styled sedans available - the M6 Gran Coupe, Audi RS7 and Mercedes CLS63 AMG S-Model.

On paper, the M6 Gran Coupe starts from the rear position on the grid with the lowest factory power figures and RWD (for acceleration). Its 560 hp / 501 lb-ft were short of the RS7's 568 hp / 516 lb-ft and the CLS63's 585 hp / 590 lb-ft. The RS7 and CLS63's AWD system also give them the 0-60 advantage, in theory.

How did these figures translate to real world performance tests? In a rolling start, the BMW was quickest, covering 5-60 mph in 4 seconds, which was 0.1 seconds faster than the CLS63 and 0.4 seconds faster than the RS7. From a standing start, the M6 GC came in third (at 3.5 sec) for 0-60 mph test at 0.1 seconds slower than the RS7 and 0.3 seconds slower than the CLS63.

As for handling? In a 610-ft slalom, the M6 hit 44.1 MPH compared to the RS7's 41.7 MPH and 42.1 MPH.
