AMG 5.5-liter V8 Biturbo engine
In terms of maximum output and fuel consumption, the AMG 5.5-liter V8 biturbo engine remains the most efficient series-produced V8 engine of all. With an output of 430 kW (585 hp) and a torque of 900 Nm, the AMG eight-cylinder unit from the BlueDIRECT engine family (in-house designation M 157) outperforms all comparable engines. The fuel consumption of the new S 63 AMG is 0.4 liters per 100 kilometres lower than that of the predecessor model, even though the engine output has been increased by up to 30 kW (41 hp). The range-topping eight-cylinder model already meets the requirements of the EU6 emissions standard, which is due to come into force in 2015.
