BMW has just given their new 2013 BMW 6-Series Gran Coupe its much-anticipated debut at the 2012 Geneva Motor Show. The big 4-door coupe (a BMW first) sports a new front fascia, some thick hips and a big rear-end. As the newest addition to the German automaker's 6-series lineup, the Gran Coupe will be powered by BMW's N55 3.0-liter turbocharged inline 6-clyinder rated at 315hp and 330 lb-ft of torque.
