In 1983, BMW installed a modified version of the M1’s engine in a 6-Series body and created the first M6. This model lasted only through 1989. But in 2005, the M6 made its comeback, and BMW added a convertible variant in 2007.

For the 2013 model year, a fully refreshed M6 has reappeared after a two-year hiatus. Its more aggressive body and stylish headlights give it new life, and a new V-8 delivers 60 more horsepower than the V-10 it replaces.

M6 coupes and convertibles have a single trim level that includes staggered alloy rims, an M chassis and suspension, and xenon headlights with auto-leveling. The M6 really makes its mark under the hood, where a 560-horsepower, 4.4-liter twin-turbo engine resides. A seven-speed M dual-clutch transmission delivers power to the rear wheels. The M6 coupe launches to 60 mph in a blistering 4.1 seconds; the heavier convertible is slightly slower with a 4.3-second time. Both models are electronically limited to 155 mph.

BMW offers two option packages for the M6. The Driver Assistance Package enhances safe driving with Lane Departure Warning, Active Blind Spot Detection, side- and top-view cameras, and speed limit information. The Executive Package adds active front seats, BMW Apps, soft-close automatic doors, LED lighting, a SiriusXM satellite radio, a heads-up display, a heated steering wheel and a power rear sunshade.
