2005 Mercedes-Benz CLK-Class CLK55 AMG 2dr Convertible

The CLK AMG is powered by a hand-assembled 5. 4-liter V8 engine. The hardware list reads like that of a race car: super-stiff forged billet steel crankshaft. forged. weight-matched connecting rods and pistons. lightweight AMG-specific chain-driven single overhead camshafts V8 (one cam per cyl bank) with two intake and one exhaust valves per cylinder. as well as 8 coil packs and 16 spark plugs (two spark plugs per cyl). Its bore and stroke are nearly the same. which makes it an ideally balanced engine. The complex dual-resonance intake manifold with carefully tuned runners helps create optimized torque and power outputs by taking advantage of two resonant frequencies to increase performance. the engine features a high compression ratio of 10. 5:1. All of these advance technologies help deliver a healthy 342 hp (255 kW) and 376 lb·ft (510 N·m) of torque.
