The Mercedes-AMG GT Black Series has a maximum power output of 720 horsepower.
Revealed in 2020, the Black Series was the most extreme road-going version of the first-generation Mercedes-AMG GT. Its hand-built 4.0-liter twin-turbocharged V8, known as the M178 LS2, produces 720 hp at 6,700–6,900 rpm and 800 Nm of torque from 2,000 to 6,000 rpm.
The engine differs from the ordinary AMG GT’s V8 in several important ways. It uses a flat-plane crankshaft rather than the cross-plane crankshaft found in other versions, allowing a different firing order and helping the engine rev higher. AMG also paired the powertrain with extensive carbon-fiber construction, adjustable suspension and elaborate active aerodynamics.
A common mix-up involves horsepower standards. Mercedes-Benz and European specifications often quote 730 PS, which converts to approximately 720 horsepower in the imperial or SAE sense. Thus, 720 hp is the canonical answer to a question stated in horsepower; 730 PS is the equivalent metric figure, not a competing output rating. The Black Series was also rated for a 202 mph top speed.
