It’s finally what Bimmer fans have been waiting for — a BMW 4-door coupe variant to compete with the likes of the Mercedes-Benz CLS and Audi’s A7. The all-new 2013 6 Series Gran Coupe instills the design characteristics of the 6 Series Coupe but offers more space and a bit more drool. The vehicle will hit the U.S. market in three versions starting with the TwinPower Turbo 6-cylinder 640i Gran Coupe, which arrives early summer of 2012. A TwinPower Turbo V8 will make a splash later in the summer as the 650i Gran Coupe. Lastly, an AWD 650i xDrive Gran Coupe will join the team shortly after. This without a doubt will be our favorite.
