The M6 is BMW's high-performance version of its 6 Series sports car. It has more aggressive, M-specific styling cues and is powered by a turbocharged V-8 engine that's rated at 560 horsepower. The M6 is available as a coupe, soft-top convertible or as a coupelike four-door, dubbed Gran Coupe. The M6 competes with the Porsche 911, Audi R8 and Jaguar XKR.

New for 2014
A traditional six-speed manual transmission is now available as a no-cost option, and the transmission includes a downshift-rev-matching feature. A seven-speed dual-clutch transmission with steering-wheel shift paddles and a launch-control function is still available.
Large carbon-ceramic brake rotors with gold-painted calipers are also optional. The brakes shave nearly 43 pounds from the M6's curb weight, and the system quickly dissipates heat, according to BMW.
All M6s get an updated version of BMW's iDrive controller system that brings revised graphics, new menu interfaces, upgraded navigation and a dictation service for composing short messages.

M6 Gran Coupe
The Gran Coupe body style is equipped similarly to the other M6 versions. The biggest differences are in the body style itself and the resulting interior space. From bumper to bumper, the Gran Coupe is 4.4 inches longer than the M6 coupe and 4.1 inches longer than the 5 Series sedan. The front seat dimensions are essentially the same as the coupe's, but the Gran Coupe boasts a roomier backseat with three rather than two positions.
- 35.3 inches of legroom versus the coupe's 30.5 inches
- 37 inches of headroom versus 35.8 inches in the coupe
- The Gran Coupe shares the coupe's 16.2-cubic-foot trunk, which is 2.2 cubic feet larger than the 5 Series sedan's trunk
