Mercedes CLS63 AMG revealed

Mercedes-Benz is out to raise the stakes with its fast new CLS63 AMG — the third model to receive its torque-laden twin-turbocharged 5.

The aggressively styled four-door pictured here officially for the foremost time having made its public premiere at today’s Los Angeles motor show is scheduled to enter production next year. It will crack on sale in the UK next May.

The new  twin-turbo 5.5-litre V8 first revealed in March has been conceived to replace AMG’s by nature aspirated 6.

  The other engine will be offered in two states of tune. In stock guise it kicks out 518bhp and 516lb ft of torque at 1750rpm. This gives the new CLS63 an additional 9bhp and 52lb foot over its predecessor.

However a performance bundle will lift those outputs to 549bhp and 590lb ft at 2000rpm. The heady reserves are channelled to the buttocks through AMG’s seven-speed MCT gearbox.

Mercedes claims 0-62mph in four.4sec in S (for Sport) and molarity (for molarityanual) modes — and 4.3sec with the optional execution package. Top speeding remains limited to 155mph but an optional driver’s package can be ordered which raises it to 186mph.

The CLS63 also gets a stop-start plan of action that operates in tandem with brake energy recuperation allowing AMG to decouple the alternator for stronger acceleration and lower consumption. Provisional figures put combined substance consumption at 28.5mpg and CO2 emissions at 232g/km which better the familiar model’s by an impressive 9.1mpg and 113g/km general.
 

 The unexampled CLS63’s front track is 24mm wider and it rides 15mm lower than the standard CLS. The suspension has MacPherson struts with steel springs up front and a multi-link set-up with AirMatic air  springs at the rear.

Compared with the standard car the CLS63 gains a deep  front bumper a uniquely designed bonnet and wider front wings with ‘V8 Turbo’ badges. It also gets slightly wider sills a delicate boot spoiler and a reprofiled rear bumper with a faux diffuser. The standard 19in force are shod with 255/35 (front) and 285/30 (rear) tyres.
