BMW unveiled what is surely going to be the American Dental Association’s Car of the Year, the 2013 BMW M6, at the Geneva Auto Show. Sporting the fat, bloated body of the 6-Series, along with the M5′s turbocharged 560 horsepower V8, we can only await the arrival of an M6 Gran Coupe now that this anticlimactic coupe has revealed itself.

Dentists and divorcees, rejoice! The BMW M6 will debut as a convertible first, with deliveries starting in June. The hardtop will go on sale later this summer – both will get all the same mechanical bits as an M5, but with only two-doors, you can shed the family image in favor of someone who pays (or receives) alimony.

The 4.4L twin-turbo V8 makes 560 horsepower and 500 lb-ft of torque, with peak twist coming between 1,500 and 5,750 rpm. A 7-speed dual clutch helps the coupe hit 62 mph in 4.2 seconds, with the cabrio taking an additional tenth. While BMW is touting the 16″ ceramic brakes, electro-hydraulic dampers and carbon fiber roof, they didn’t release any weight specifications for the car. The previous versions weighed in the neighbourhood of 4,000 and 4,400 lbs, gargantuan figures for a passenger car. BMW cited a power/weight ratio of 7.3lb/hp for the coupe and 7.7lb/hp for the convertible, which suggests a curb weight of 4088 lbs for the coupe and 4312 lbs for the ragtop. Plus ca change, plus c’est la même chose. Or whatever the German equivalent is.
