Despite its size, the M6 handles in a neutral manner but is also capable of big smoky power slides thanks to its potent turbocharged engine. - Motor Trend

The riding experience in the Convertible M6 worth the six-figure price of the premium convertible.

The competitors like Mercedes SL 550 Roadster, Porsche 911 GTS Cabriolet, and Jaguar F-Type R Convertible come to a halt from 60 to 0 mph in 113, 112 and 113 feet respectively. Their figures are helped by their relatively lower curb weight, although in the real world, these figures do not have any significant difference.

2018 BMW M6 Convertible Fuel Economy

6.5/10

The M6 has a driver-centric and stylish design. The dash joins gracefully with the large center console for a wraparound feel. Intuitive controls, excellent materials quality. - Edmunds

Seating and Comfort

BMW M6 Convertible has a passenger capacity of four which is commendable considering the convertible nature of the car.

The premium convertible offers spacious and comfortable front passenger seats with a significantly good amount of head/shoulder/legroom in the front. The rear seats are just acceptable as they don't offer spacious seating especially if you're six feet tall.

Porsche GTS is the only other car here that offers rear seats, however inadequate they may be. None of the cars here are known for their interior space. Jaguar's low roofline makes for least headroom in the segment.

Infotainment System

BMWs most advanced iDrive infotainment system is one of the major highlights of this premium convertible, featuring a 10.1-inch display.  Other than that, it gets:

  • Harman Kardon or Bang & Olufsen sound system
  • Wi-Fi connection
  • wireless device charging
  • Sat-Nav system
  • USB connectivity
  • Apple CarPlay (Optional)

The only setback in the infotainment system is that it doesn't offer Android Auto smartphone integration. 

Cargo Capacity

BMW M6 convertible offers best in class cargo capacity of 10.6 feet cube which is one of the best cargo capacity offered by convertibles. The luxury convertible can handle cargo of four people for a weekend outing. The boot was well managed and convenient.

2018 BMW M6 Convertible Exterior

9.0/10

The 2018 BMW M6 is a high-performance luxury convertible available in a single trim level. It stands apart from other 6 Series convertibles with sporty elements such as unique front and rear fascias, quad tailpipes and a range of other equipment. - Edmunds

Dimensions and Weight

BMW X6 Convertible will impress you with its premium exteriors and looks. The powerful convertible's exteriors offer premium adaptive LED headlights, 19" alloy wheels and bigger kidney grills on the board. The car features astonishing looks and premium convertible experience which justify its higher price than rivals.

BMW M6 Convertible has a high curb weight of 4515 lbs; higher than its competitors. The luxury convertible also has quite imposing dimensions, and at 193 inches, it is quite a fair bit longer than others.

The 2018 M6 convertible has an impressive class ground clearance of 4.2 inches which is enough to save the underbelly from nasty scrapes. The wheelbase, also longest in class, at 112.2 inches increases the turning diameter by a lot, and fitting into or pulling out of tight parking spaces might become a pain.
