BMW 6 Series

New 2013 6 Series Gran Coupes debuted in spring, 2012 offering the same features and powertrains as the coupes and convertibles, and the 650i models' TwinPower turbo V8 is upgraded to 445 horsepower and 480 lb-ft of torque, 45 more horses and 30 more lb-ft than in 2012. The M6 Coupe and Convertible boast BMW's most powerful production engine ever, a 560-hp 4.4-liter TwinPower turbo V8, up five hp with the same 500 lb-ft of torque as the V10 it replaces, and 25 percent more fuel efficient.

The 2012 BMW 6 Series is about as all-new as an all-new model can be. Aside from an overwhelming list of new features and technologies, the 6 Series lineup will now include a 6-cylinder turbo engine option (640i Coupe and 640i Convertible) and available all-wheel drive (650i xDrive Coupe and 650i xDrive Convertible). Later we'll see a high-performance M6 model and a first-ever 4-door 6 Series in the spirit of the Mercedes-Benz CLS and Audi A7.

Changes for 2010 include equipment improvements to the navigation system software and the availability of BMW's Individual options, including Individual full Merino Leather, Individual paint work and Individual interior trim.

This year's Sport Package is upgraded to include new 19-inch forged alloy wheels, an anthracite-color headliner (Alcantara in the Coupe or fabric in the Convertible), dark chrome exhaust tips, a contoured hood, sport-tuned exhaust and sport seats with Shadowline trim.

The 6 Series receives a modest exterior freshening, with a new grille and front end, as well as new headlight lenses with LED turn signals and power-folding mirrors. Interior changes include a revised iDrive with six programmable memory buttons, while models equipped with the Sport Automatic receive steering-wheel paddle shifters. Dynamic Cruise Control is made standard while the Lane Departure Warning System is added to the option list.
