Mercedes-Benz has been kind enough to give us all a glimpse of the company’s 2013 G63 AMG ahead of the super SUV’s debut at the 2012 Beijing Motor Show. A 5.5-liter AMG-built twin-turbo V8 engine lurks behind the updated face, complete with a heady 544 horsepower and 560 pound-feet of torque. The direct-injection engine is also laden with fuel-saving gear, including a start/stop system and an intelligent alternator that only charges the vehicle’s electrical system when needed. Funk Flex
