13. BMW M6 Gran Coupe
But ... there's already an M6 Coupe, you say. Yes, there sure is, but there's no Gran Coupe, which will live in between the M6 and the M5, as a competitor to the Audi S7 and the Mercedes-Benz CLS63. A direct-injected 4.4-liter twin-turbo V8 will send 560 horsepower and 500 lb-ft. of torque to the rear, controlled by a seven-speed dual-clutch transmission with an Active M differential.
