So after the official pictures of the new M6 Gran Coupe leaked out BMW decided to release the official material. And as expected the only new bit in it was the price, which is 128.800 Euro in Germany where the car goes on sale from May 2013.

Let’s review the details of BMW M6 Gran Coupe one more time. It has a 4.4 liter twin-turbo V8 engine developing 560 horsepower and 680 Newton metres (502 lb-ft) of torque. That power translates into a 0 to 100 km/h time of 4.2 seconds, which is great for a four-door car, and the top speed is, as usual, limited to  250 km/h/155 mph.

However, if you pay BMW more money and buy the M Driver’s Package, they will raise the top speed to 305 km/h/189 mph. As for the consumption – not that anybody cares – the Gran Coupe M6 manages 9.9 litres per 100 kilometres (28.5 mpg imp) and CO2 emissions of 232 grams per kilometre.

As with every BMW M car, the M6 has great mechanical features, but every single one of them is governed by a separate computer. You get the seven-speed M Double Clutch Transmission with Drivelogic, Active M Differential at the rear axle with DSC (Dynamic Stability Control), Double Wishbone suspension with Dynamic Damper Control system and hydraulic variable-ratio rack-and-pinion steering with the M Servotronic function.

Standard features of the M6 Gran Coupe include 20-inch M light-alloy wheels, leather trim, heated driver and front passenger seats, automatically dimming rear-view and exterior mirrors, an alarm system and the BMW Professional radio with hi-fi loudspeakers. Available as an alternative to the standard 2-zone automatic climate control is a 4-zone system with a control panel in the rear compartment. Among the other highlights of the options list are M multifunction seats, heated rear seats, Comfort Access, a heated steering wheel, the Soft Close Automatic function for the doors, electrically operated sun blinds, the new generation of the Professional navigation system and a Bang & Olufsen High End Surround Sound System.
