BMW has officially unveiled the 2013 M6 Coupe and Cabriolet, fitting it with a twin-turbocharged 4.4 liter V8 that dishes out 560 horsepower and 500 lb./ft. of torque. The performance numbers are stunning yet expected from the sports car. The seven-speed dual-clutch transmission is the same as the one in BMW’s M5 and helps the M6 go from 0 to 62 mph in 4.2 seconds. The German automaker’s Active M Differential is also included in the vehicle and works with the DSC and the Dynamic Damper Controls. The carbon fiber roof and other fine details allow throughout the vehicle make this beauty a complete package if you will. No word on pricing just yet but we should see it hit salesrooms by June of this year.
