Unveiled during this year Geneva Motor Show, this spring, the new Mercedes S-Class Coupe is the ultimate luxury coupe with plenty of power under the hood and with a very nice interior.
AutoExpress is enjoying all this in the first driving session with the large and powerful coupe, available only in S53 AMG Coupe. Lightweight construction has reduced the vehicle weight by 65 kilograms (143 pounds) – even though the car has a higher output and more extensive standard equipment than the predecessor model.
In terms of maximum output, torque and fuel consumption, the AMG 5.5-litre V8 biturbo engine remains one of the most efficient series-produced V8 engines of all. With an output of 430 kW (585 hp) and 900 Nm of torque, the AMG eight-cylinder unit from the BlueDIRECT engine family meets even the most demanding of requirements.
Fuel Economy 
Compared to the previous CL 63 AMG model, engine output has been increased by 30 kW (41 hp) and torque by 100 Nm. Yet the S 63 AMG Coupé still consumes less fuel: The NEDC combined figure of 10.1 l/100km (23 mpg) makes the two-door model the most fuel-efficient model in its competitive segment.
