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.
