In the German Touring Car Championships (DTM) the new AMG C-Class ensures exciting motor racing at the highest level, and now its roadgoing sister model is celebrating its debut: the new C 63 AMG. Its AMG 6.3-liter V8 engine develops a peak output of 336 kW/457 hp and a maximum torque of 600 newton meters – unrivalled figures in this segment. Accordingly the C 63 AMG accelerates from zero to 100 km/h in 4.5 seconds, while its top speed is electronically limited to 250 km/h.
In conjunction with an all-new front axle, speed-sensitive AMG sports steering and the new, 3-stage ESP, the AMG sports suspension en-sures both outstanding driving enjoyment and exemplary handling dynamics. A combination of expressive design, a decidedly sporty in-terior and a high level of everyday practicality makes the C 63 AMG a unique high-performance car. The market launch will commence in early 2008.

Merely the appearance of the C 63 AMG is impressive enough, with its wide, road-hugging stance. The new bonnet with its prominent power domes con-ceals the independently developed AMG 6.3-liter V8 engine, which develops a fulminating 336 kW/457 hp at 6800 rpm from a displacement of 6208 cubic centimeters. In this respect the C 63 AMG comes very close to the 470 or so horsepower delivered by the AMG C-Class racing touring car in the DTM series. This high output also benefits the power-to-weight ratio, which is a very favourable 3.6 kg/hp.

The torque developed by the AMG 6.3-liter V8 engine need fear no com-parison either. The maximum of 600 newton meters at 5000 rpm is unri-valled in this class, and the torque curve is equally impressive: from 2000 to 6250 rpm the driver always has more than 500 newton meters on tap – ideal for powerful acceleration in any engine speed range.

Key data for the C 63 AMG at a glance:

• Cylinder arrangement: V8
• valves per cylinder: 4
• Displacement: 6208 cc
• Bore x stroke: 102.2/94.6 mm
• Compression ratio: 11.3 : 1
• Output: 336 kW / 457 hp / 6800 rpm
• Max. torque: 600 Nm / 5000 rpm
• Acceleration 0-100 km/h: 4.5 sec
• Top speed: 250 km/h*

* Electronically governed

This high-performance eight-cylinder engine has the perfect partner in the form of the AMG SPEEDSHIFT PLUS 7G-TRONIC transmission. Equipped with AMG steering wheel shift paddles and three driving modes, the seven-speed automatic transmission allows a decidedly sporty or more comfort-oriented style of driving according to the driver’s preference. The different modes - “S” (Sport), ” C” (Comfort) and “M” (Manual) differ in their shift characteristics and speed: gearshifts in “S” mode are around 30 percent faster than in “C”, and no less than around 50 percent faster in “M” mode. Pressing a button is sufficient to activate the desired driving program.

The new C 63 AMG is the very first AMG car to feature an automatic throt-tle-blipping function during downshifts. This not only enhances the driver’s emotional experience – the almost completely jolt-free downshifting process also reduces the load-change responses and has a particularly positive ef-fect when braking before bends on the racetrack.
