Mercedes CLK 63 AMG Black Series: Further Engine Details

Press Release

Made entirely from high-strength aluminium, the naturally aspirated V8 engine is packed with a wealth of fascinating racetrack technology that reflects AMG's rich motorsport heritage. The vertical arrangement of the intake and exhaust ports together with the sophisticated new variable intake manifold featuring two integral throttle flaps results in perfect cylinder charging. The use of bucket tappets in the cylinder heads paves the way for an unyielding valve train and therefore high rev speeds. Variable camshaft adjustment, an extra-rigid closed-deck crankcase and cylinder walls with a revolutionary new LDS coating are further attributes of this ultra-sophisticated V8 engine made by Mercedes-AMG.

The electronically controlled fuel supply operates with a system pressure of between 3.8 and 5.0 bar, depending on current requirements. The fuel pressure is adjusted instantaneously to match the power demands and outside temperature. The engine electronics translate the command from the accelerator into a corresponding specified target pressure in a matter of milliseconds. This variable control guarantees spontaneous response combined with sporty overrun characteristics throughout the full spectrum of engine loads and rev speeds.

This unique combination of a high-revving concept and a large displacement achieves the best of both worlds: exhilarating, free-revving flexibility accompanied by high pulling power at low engine speeds. The decidedly sporty character of the CLK 63 AMG Black Series manifests itself in the form of tremendous agility across all engine speed ranges. The new AMG V8 delivers 500 Newton metres of torque to the crankshaft as low down as 2000 rpm, while the maximum of 630 Newton metres is on tap at 5250 rpm. In the AMG engine manufacturing facility, each engine is traditionally built according to the "One man, one engine" philosophy. Every AMG V8 engine is hand-assembled from start to finish by a single engineer in accordance with the strictest quality standards– as verified by the engineer's signature on the AMG engine plate.
