The advanced AMG 6.3 litre V8 engine produces a peak output of 571 hp (420 kW) at 6800 rpm, making the SLS AMG one of the most powerful sports cars in its segment. Accelerating from 0-62 mph takes just 3.8 seconds.

Key measures implemented to enhance performance include a complete redevelopment of the intake system, a redesigned valve assembly and camshafts, the use of a flow-optimised tubular steel exhaust manifold, and de-restriction of the exhaust system.

The 8-cylinder engine reacts with agility to accelerator pedal movements and demonstrates greater responsiveness across the entire engine speed range. The conversion to dry sump lubrication allows a significantly lower engine mounting position, with the resulting lower centre of gravity enabling high lateral acceleration and scintillating vehicle dynamics.
