Nearing the end of its life, the M6 Gran Coupe is still competitive among other four-door performance sedans thanks to a brilliant 4.4-liter twin-turbo V8. Producing 552 horsepower and 500 lb-ft of torque, the M6 provides true M-car performance and will hit 60 mph in only 4.1 seconds. Rear-wheel-drive and a seven-speed dual-clutch automatic transmission are standard, while a six-speed manual is a no-cost option for true purists.
The alluring exterior features 20-inch M double-spoke wheels in gloss black, along with the traditional quad exhaust pipes (in a chrome finish) at the back. Merino leather upholstery, a 16-speaker Harman Kardon sound system, and power-adjustable seats are just a few of the highlights to be found in the stylish, beautifully constructed cabin.
