Unique to the SLS AMG GT is its 6.3-liter naturally aspirated V-8. With peak output of 583 hp @ 6,800 rpm and 479 lb-ft or torque @ 4,750 rpm, it is among the most powerful engines of its kind to be fitted standard to any automobile currently in production. Numerous racing-derived features team up to deliver its monumental output with lightning-quick response, not merely in acceleration but in response to every driving condition from engine braking into a corner to pouring on the power as you exit. Forged-alloy pistons, a highly rigid one-piece bedplate, and reinforcement of the crankshaft, valvetrain and four overhead camshafts assures enduring performance, whether in the heat of competition or over years of enjoyment. Extensive attention to weight reduction includes replacement of virtually every steel screw with aluminum, magnesium intakes, the lighter forged pistons, and optimization of numerous components, from the connecting rods to the oil pump.
The result is impressive in four key measures: A class-leading 1.28 hp per pound of engine weight. Specific output of nearly 94 hp per liter of displacement, all without the of turbocharging. A 0-60 time of just 3.6 seconds for both the Coupe and Roadster. And a top track speed of 197 mph.
