The BMW M6 returns this year after a two-year hiatus, in the form of both a Coupe and Convertible. Gearheads should be pleased with the engine, which is the same a twin-turbocharged 4.4-liter V8 found under the hood of the M5. It has the highest output ever from a BMW M car — 560 horsepower and 500 pound-feet of torque, good for a 10% increase in power over its predecessor while fuel consumption has decreased by 30%. The engine is mated to a newly developed seven-speed dual-clutch gearbox that allows the Coupe to go from rest to 62 mph in 4.2 seconds, with the Convertible just behind at 4.3 seconds. Drivers should appreciate the benefits of the Active M Differential, an electronically controlled multi-plate limited-slip differential that optimizes traction, stability and sport drive character. It works in conjunction with the Dynamic Stability Control (DSC), as well as the Dynamic Damper Controls (DDC) that use electro-hydraulic damping force adjustment on the fly.
The M6 will be the first BMW M to offer optional carbon-ceramic brakes (paired with 20-inch light alloy wheels). The brake rotor measures 16.1-inches in front, combined with six piston blue calipers, plus 15.6-inch rotors in the rear 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 tires in the back.
Look for the Convertible to hit showrooms in June, with the Coupe arriving later in the summer as a 2013 model. Check out multiple images of both models in the gallery following the click. via: Autoblog
