After a momentary slip-up showing the upcoming AMG version of the 2014 Mercedes-Benz S-Class, we now have the first official teaser for the 2014 S63 AMG.

Though there's not much other than a quick pass by the lower portion of the car, we can see a license plate--starting with 'S' and including the number '63', aggressive lower aerodynamics at the nose, a V8 Biturbo badge on the digital tachometer, and a quick pan down the side.

Mercedes-AMG has yet to reveal any official details on the car, but we expect the 5.5-liter twin-turbo V-8 found in the E63 AMG to get the call for S63 AMG duty, too, rated at 550 horsepower or more. A seven-speed AMG Speedshift transmission and all-wheel drive are also expected as standard equipment in the U.S.
