At 4.4 inches longer than the 6 series two-door coupe, the first four-door Gran Coupe available in the United States will be in 640i trim, utilizing BMW’s N55 3.0-liter turbocharged inline six and will produce 315 horsepower and 330 lb-ft of torque. A 650i Gran Coupe will be available next, providing a 4.4-liter twin-turbo V8, making 445-hp and 480 lb-ft of torque. The 650i Gran Coupe will be available in rear wheel drive and xDrive all wheel drive as well. Both the 640i and 650i will receive an 8-speed automatic transmission.
From the inside, the sporty, luxurious, and tech loaded interior of the 6 series Gran Coupe is certainly on par with its trendy competitors. While the photo gallery clearly displays a rear center console, a common design for four-passenger four-door coupes, the seat-belt placement suggests that the rear seating can provide room for three in a pinch, where the middle passenger must straddle the console.
As BMW will likely organize the debut of its new 3 Series at the upcoming 2012 Detroit Auto Show, the debut of the 2013 6 Series Gran Coupe will likely be slated for the 2012 Geneva Motor Show instead.
