The new Mercedes-Benz S63 AMG coupe has made its public debut at the New York motor show. The hot version of the S-class coupe will go on sale in the UK in November at an estimated price of approximately £100,000.
Power for the hot new coupé comes from AMG’s twin-turbocharged 5.5-litre V8 engine. With 577bhp at 5500rpm, the direct-injection petrol unit kicks out 40bhp more than the similarly configured engine used by the CL63 AMG. Torque remains the same as before, with a peak of 663lb ft at 2250rpm.
The heady reserves are channelled through a standard seven-speed AMG Speedshift automatic gearbox. As with the recently introduced S63 AMG saloon, buyers can now choose between standard rear-wheel drive and optional 4Matic four-wheel drive.
Mercedes-Benz claims a 65kg reduction in overall weight over the old CL63 AMG, both for the rear-wheel-drive and four-wheel-drive S63 AMG coupés, which are claimed to weigh the same 1995kg.
The identical weight is down to differing underpinnings. The rear-drive car has as standard AirMatic air suspension with optional corner tilt function, whereas the four-wheel-drive version receives a more conventional and lighter steel-sprung suspension.
The rear-drive S63 AMG coupé is claimed to hit 62mph from standstill in 4.3sec and return 28.0mpg. The S63 AMG coupé 4Matic can crack 0-62mph in 3.9sec and is rated at 27.4mpg. Each model has a top speed limited to 155mph.
As well as air suspension, the rear-wheel-drive S63 AMG coupé comes with Mercedes-Benz’s so-called Magic Body Control system. This consists of a number of different functions, including the road surface scanner and active body control system available on the S63 AMG saloon.
