The S 63 AMG Coupé is the latest model to benefit from the systematic implementation of the AMG Lightweight Performance strategy. Lightweight construction has reduced the vehicle weight by 65 kilograms -- even though the car has a higher output and more extensive standard equipment than the predecessor model. This weight saving was achieved largely thanks to the use of a lightweight lithium-ion battery, AMG forged light-alloy wheels and a weight-optimised AMG high-performance composite braking system. Furthermore, the entire outer skin and the front end of the body are madeof aluminium. The reduced weight improves driving dynamics and cuts fuel consumption, while the low power-to-weight ratio of 3.41 kg/hp results in effortlessly superior performance: the S 63 AMG Coupé accelerates from 0 to 100 km/h in 3.9 to 4.3 seconds, depending on model variant, and goes on to reach a top speed of 250 km/h (electronically limited).
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. 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 litres per 100 kilometres makes the two-door model the most fuel-efficient model in its competitive segment. This reduction of up to 0.4 litres per 100 kilometres and compliance with the EU6 emissions standard show that performance, efficiency and environmental compatibility are by no means mutually exclusive at Mercedes-AMG.
