The AMG 4.0-litre V8-biturbo engine in the S 63 4MATIC+ Cabriolet and Coupé comes exclusively in the highest performance stage to date rated at 450 kW (612 PS). The peak torque of 900 Nm also represents a new maximum. It is available across a wide rev range between 2,750 and 4,500 rpm, and thereby provides a sense of superior poise. The sprint from standstill to 100 km/h takes just 3.5 seconds, and the fulminating acceleration continues until the electronically limited top speed of 250 km/h is reached (with AMG Driver’s Package: 300 km/h).
The further advanced AMG 4.0-litre V8-biturbo engine utilises well-proven twin-turbo forced induction, with the two chargers not located outside on the cylinder banks but rather between them in the V of the cylinders. The advantages of the “hot inner V” are a compact engine design, spontaneous response of the turbochargers and low exhaust emissions thanks to optimal airflow to the near-engine catalysts.
