From there, the M6 convertible adds 19-inch alloy wheels, adaptive suspension dampers, a limited-slip rear differential, adaptive LED headlights, front and rear parking sensors, automatic wipers, automatic soft-close doors, auto-dimming side mirrors with heating, keyless entry and ignition, heated power front seats, driver-seat memory settings, leather upholstery and trim, a power-adjustable steering wheel and carbon-fiber accents.

Also standard are Bluetooth, adjustable drive settings, BMW's iDrive interface (with a 10.2-inch display), a rearview camera, voice controls, a navigation system, wireless device charging, a USB port, and a 16-speaker Harman Kardon surround-sound audio system with HD and satellite radio.

The M6 convertible's Executive package adds a heated steering wheel, ventilated and massaging front seats, and a 16-speaker Bang & Olufsen audio system. The Driving Assistance package features a lane departure warning system, blind-spot monitoring, a forward collision warning system, low-speed collision mitigation, and a head-up display. The Parking Assistance package adds side- and top-view parking camera views.

For more power (or if you want to take your M6 Gran Coupe to the track), you can get the Competition package that increases engine output by 40 hp. It also includes lightweight wheels; revised tuning for the suspension, steering and rear differential; retuned stability control that provides a higher threshold for intervention in the M Dynamic mode; and a black chrome finish for the tailpipes.

Stand-alone options include an alternative 20-inch wheel design in silver or black, carbon-ceramic brakes, a beige convertible top, Apple CarPlay compatibility, and an infrared night-vision system with pedestrian detection.
