2011 Mercedes-Benz SLS AMG Gullwing

More Power from AMG’s Stonking V-8

Powering the SLS is a revised version of AMG’s now-familiar 6.2-liter 32-valve V-8. In the SLS, the engine makes 563 hp at 6800 rpm and 479 lb-ft of torque at 4750 rpm. Revisions to the engine for use in the SLS include a new magnesium intake with eight separate velocity stacks; two electronically controlled throttle plates feed the new intake. On the exhaust side, a new equal-length exhaust manifold reduces backpressure. Lubricating the engine is a new dry-sump system that allows the engine to sit low, thus reducing the center of gravity. But the engine doesn’t just sit low; it also sits behind the front axle line, an arrangement that is partially responsible for the SLS’s claimed 48 percent/52 percent front/rear weight distribution.
