Perfect cylinder charging is guaranteed by the vertical arrangement of the intake and exhaust ducts, as well as the magnesium variable intake manifold with two integral throttle flaps. Other high-tech features include variable camshaft adjustment, four-valve technology with bucket-type tappets, a particularly rigid aluminium crankcase of closed-deck design and the low-friction TWAS coating on the cylinder contact surfaces.
Among the particular strengths of the AMG V8 engine are outstanding responsiveness and enormous pulling power - by virtue of its large displacement, it develops over 30 per cent more torque than comparable engines in this performance class. Electronically controlled fuel delivery is another reason for the outstanding agility and responsiveness to movements of the accelerator. With its sporty AMG sound, which was designed-in during a series of sophisticated trials, this eight-cylinder powerpack from Affalterbach offers the unique excitement of a fast-revving, naturally aspirated engine - an audible and immediate experience whether at low, medium or high engine speeds.
In the interests of optimal reliability, the C 63 AMG has a particularly efficient water cooling system and large engine and transmission oil coolers. Located behind the large apertures in the AMG front apron, these coolers ensure non-critical operating temperatures at all times – even under the extreme stress of the racetrack.
Like all AMG high-performance engines, the AMG 6.3-litre V8 is built in the AMG engine shop on the traditional “one man, one engine” principle. This means that one technician is responsible for hand-assembling a complete V8 engine to the highest quality standards - which is attested to by his signature on the AMG engine plate.
AMG SPEEDSHIFT PLUS 7G-TRONIC with blipping function
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 per cent faster than in “C”, and no less than around 50 per cent faster in “M” mode. Pressing a button is sufficient to activate the desired driving programme.
The new C 63 AMG is the very first AMG car to feature an automatic throttle-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 effect when braking before bends on the racetrack.
