Prototypes of Mercedes-Benz’s all-new C63 AMG have shed much of their disguise to reveal a aggressive styling and aconfident stance. The new performance saloon will hit the UK early next year after a public debut at the LA motor show in November.
Like other new C-class models, it will be bigger and more upmarket than its predecessor. It will feature a classy, roomier interior and more advanced features than ever before, including new state-of-the-art stereo and camera-assisted safety functions and a full suite of connectivity options.
At the heart of the C63 is AMG’s new twin-turbo 4.0-litre V8 petrol engine. Set to be revealed in the Mercedes GT AMG, the aluminium-block unit shares vital architectural elements with the 2.0-litre, four-cylinder engine used in the A45, CLA45 and GLA45.
Details remain under wraps, but AMG sources suggest that the new V8 develops between 480bhp and 580bhp, depending on the level of tune. A source said: “We can go higher if required by increasing boost pressure. But for the moment, we’re happy with the levels we’ve achieved.”
The unit earmarked for the new C63 will be at the lower end of the scale but above the 451bhp of the naturally aspirated 6.2-litre V8 used by the current C63. The adoption of forced induction also promises to lift peak torque well beyond 442lb ft at far lower revs than the 5000rpm of today’s C63.
Channelling the drive on the new car is an updated version of AMG’s seven-speed Speedshift automatic gearbox, with new software mapping and fuel-saving features such as brake energy recuperation, automatic stop-start and a new coasting function.
