4.0-litre V-8 biturbo engine with twin-scroll turbochargers.
The AMG 4.0-litre V-8 Biturbo engine in the S 63 4MATIC+ comes exclusively in the highest performance stage to date rated at 450 kW (612 hp). The peak torque of 900 Nm also represents a new maximum. It is available across a wide rev range between 2750 and 4500 rpm, and thereby provides a sense of superior poise. The sprint from standstill to 100 km/h takes just 3.5 seconds, faster than in any other performance luxury saloon, and the dynamic push in the back does not end before reaching the electronically limited top speed of 250 km/h (with AMG Driver's Package: 300 km/h).
'AMG Cylinder Management' cylinder deactivation system
For maximum efficiency, Mercedes-AMG equipped the V-8 engine in the S 63 4MATIC+ with the AMG Cylinder Management cylinder deactivation system. In the partial-load range, cylinders two, three, five and eight are deactivated, which significantly lowers the fuel consumption. With a combined fuel consumption of 8.9 litres and combined CO2 emissions of 203 grams per kilometre, the new S 63 4MATIC+ is among the leaders in its competitive segment.
For the first time, the S 63 is fitted with the AMG SPEEDSHIFT MCT 9-speed sports transmission, which impresses with extremely short shift times, fast multiple downshifts and a rev-matching function. A wet start-off clutch replaces the torque converter of the production model. This saves weight and improves the response to the driver's accelerator pedal input, particularly during acceleration and load changes.
