July 16, 2005 Not as yet presented in an automobile, Mercedes-AMG has released details of its new high-revving, large displacement 6.3-litre V8 engine. Developed entirely by AMG, this engine generates 375 kW/510 hp at 6800 rpm, with a maximum torque of 630 Newton metres, making it the world’s most powerful naturally aspirated eight-cylinder production engine. That’s around 20 percent more torque than comparable naturally aspirated engines in this performance class. Made completely from high-strength aluminium, the V8 has a wealth of features derived from motorsport such as a variable intake manifold, the vertical arrangement of the intake and exhaust ducts, variable camshaft adjustment, a particularly rigid closed-deck crankcase and cylinder walls with a new LDS coating.
