What's the new M6 made of? Just like the last generation, it takes all the best bits from the M5 and distills them into two door form. And this time, the convertible comes first.

At its heart, the M6 Coupe and Cabriolet are all about the engine, and as expected both models use the same twin-turbocharged 4.4-liter V8 (ironically codenamed S63) to output 560 horsepower and 500 pound-feet of torque, the latter of which peaks between 1,500 and 5,750 rpm. Those figures should sound familiar, as they're almost exact duplicates of the M5's specs (the sedan makes an additional two lb-ft of torque), including the 7,200 rpm rev limiter and Valvetronic system.

Mated to the same seven-speed dual-clutch gearbox as the M5, BMW claims the M6 Coupe will run from a rest to 62 mph in 4.2 seconds, with the cabrio taking an additional tenth of a second to hit the same mark. According to our sources, a six-speed manual option is under consideration, but it won't be available at launch. And again, just like the M5, fuel consumption has been reduced by 30 percent while power has increased by around 10 percent.

Also included is BMW's Active M Differential, an electronically controlled multi-plate limited slip diff that works in conjunction with the DSC and the new Dynamic Damper Controls that electro-hydraulically tweak damping force on-the-fly depending on the settings and the situation.

Inside the subtly blistered wheel arches are massive 16.1-inch carbon ceramic rotors in front, gripped by six piston blue calipers, with equally impressive 15.6-inch rotors out back held by a single-piston caliper. The standard wheels are M-specific 19-inch alloys with 265/40 R19 ultra-high performance summer tires in front and 295/35 R19 rubber in the rear, with 20-inch lightweight hoops available as an option.

BMW isn't citing exact curb weights for either the coupe or cabrio yet, but assures us that they're notably less than the previous E63/E64, and the double-bubble carbon fiber roof on the coupe is a visual testament to that.

Sales of the convertible will start this June, with the coupe arriving later this summer as a 2013 model. And we hear we'll get to see the drop top in person at the New York Auto Show, with the coupe debuting in Geneva. Hit the jump for all the tech-laden details.Continue reading BMW debuts 560-hp twin-turbo M6, manual option under consideration
