Barely a month after going on sale in the U.S. comes word that the new BMW 6 Series Gran Coupe pictured here will spawn an even more intense M-spec sibling sometime next year. Save for confirming its existence and the rather broad potential launch window, the automaker has yet to release any details on the package. However, the BMW M6 Gran Coupe is almost certain to share the same basic powertrain mechanicals as the existing M6 (as well as the M5 an X5 M) models -- namely a 560-horsepower/4.4-liter twin-turbocharged V8 that makes 500 lb-ft of torque and sends that force to the rear wheels via BMW's 7-speed M-Double Clutch Transmission (M-DCT) and an Active M Differential that optimizes power transfer.
As with the M5/M6, there's still some question as to whether the new BMW M6 Gran Coupe will offer a 6-speed manual gearbox at some point. It will, however, get the full range of M-spec chassis, cabin and cosmetic enhancements.
In other BMW-related news, the automaker also has confirmed that it will be bringing a pair of new turbodiesel engines to the American market, a 2.0-liter/4-cylinder that will arrive sometime next year and a 3.0-liter/inline-6. While no other details were offered, both are believed to use a single turbocharger and could well see duty the recently-released 3 Series as well as in the 5 Series and X5 lines.
