Official: BMW reveals 2012 6 Series M Sport and diesel models

BMW is expanding its 6 Series line. The automaker has just announced information on the 2012 640d Coupe and 640d Convertible. The two-door oil-burners aren't expected to make it Stateside, and that's a pity, as they make use of a twin-turbocharged 3.0-liter straight six with 313 horsepower and a hefty 464 pound-feet of torque. All that twist helps the coupe hit 60 mph in around 5.5 seconds while returning 51.4 mpg on the Imperial scale. BMW is also offering the 6 Series with xDrive for the first time as well, but only on 650i models. Thankfully, buyers can expect to see the all-wheel-drive coupe in North American dealers later this year.If chugging along with a diesel under your hood isn't quite your speed, you'll be happy to know that BMW is also offering a 6 Series M Sport for 2012. The package includes special aerodynamic additions as well as LED fog lamps and 19-inch, double-spoke aluminum alloy wheels. Inside, sport seats are trimmed in Alcantara and leather as well as an M Sport steering wheel. - Autoblog
