Under the SLS AMG's long hood is a version of the V-8 that we've seen powering every Merc of this generation with an AMG badge--although, this time the engine actually displaces 6.3-liters. Output has been tuned to 563 horsepower and 479 pound-feet of torque. The extra power comes partially from all-new intake and exhaust systems and a rejiggered valve train.
Power flows through a SpeedShift 7-speed dual-clutch gearbox and down an exotic carbon fiber driveshaft before meeting the road at the rear wheels. The gearbox features three driving modes for Comfort, Sport, and Sport plus, as well as an automated manual mode. Sixty miles per hour happens in a blistering 3.7 seconds with a top speed of 197 mph.
Dispite its wing doors, the SLS AMG is more at home on the road than in the sky.

In addition to the wingdoors that hinge upward from the roof, the also SLS features the classic long-hood, short overhang design of the sports cars of old, with a small passenger compartment mounted just ahead of the rear axle.
