Mercedes-Benz CLK 63 AMG

A new top V8 model is making its debut in Geneva in the form of the CLK 63 AMG. The 100% AMG-developed 6.3-litre V8 engine under the bonnet promises a truly memorable driving experience. Available in both Coupe and Cabriolet guise, the CLK 63 AMG eclipses the power and torque figures for any other model in this segment with a maximum output of 354 kW/481 hp and 630 Newton metres of peak torque.

Compared to its predecessor, the CLK 55 AMG, power has been upped by 84 kW/114 hp (+31 percent) and torque by 120 Newton metres (+23 percent) in the CLK 63 AMG. With new AMG high- performance composite brakes, a new AMG sports suspension, new AMG 18- inch light-alloy wheels plus exclusive and dynamic standard appointments, the new CLK 63 AMG is the sportiest and most elite CLK to date.

The new AMG 6.3-litre V8 engine delivers truly explosive performance: the CLK 63 AMG Coupe sprints from standstill to 100 km/h in 4.6 seconds (predecessor: 5.2 s), with the Cabriolet taking 4.7 seconds (predecessor: 5.4 s). The electronically limited maximum speed is 250 km/h. The majestic power delivery of the Mercedes-AMG V8 engine permits either electrifying acceleration or relaxed cruising in a high gear with ample power reserves. The new 6.3-litre V8 engine from AMG is the first in the world to combine the high-revving concept with a large displacement. Developed exclusively by AMG, this high-performance engine delivers 20 percent more torque than comparable naturally aspirated engines with a similar power rating.

AMG V8 naturally aspirated engine with an array of high-tech features Made entirely from high-strength aluminium, the V8 naturally aspirated 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 superlative cylinder charging.

The use of bucket tappets in the cylinder heads paves the way for a stiff valve train and therefore high engine 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.

This unique combination of a fast-running design and a large displacement achieves the best of both worlds: exhilarating high-revving flexibility accompanied by high pulling power at low engine speeds. The decidedly sporty character of the CLK 63 AMG manifests itself in the form of tremendous agility and dynamic responsiveness 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 5000 rpm.

The new AMG V8 unit promises dynamic acceleration, instantaneous pickup and sheer driving pleasure at the highest level. With its new, sporty AMG soundtrack which was fine-tuned during an extensive series of tests, the eight-cylinder powerpack from Affalterbach offers all the spine-tingling excitement of a high- revving V8 naturally aspirated engine that makes its presence both heard and felt at any engine speed.
