At the same time as the S 63 4MATIC+, the top-of-the-range model S 65 receives a visual update that underscores the superiority of the high-end 12-cylinder model. Its 6.0-litre V12 biturbo engine retains its output of 463 kW (630 PS) and peak torque of 1,000 Newton metres. Thanks to the highest stage of development of the V8 and V12 biturbo engines, both new models deliver more output and torque than the competitors.
New engine, new transmission, new all-wheel drive, new exterior and interior design: On the S 63 4MATIC+, Mercedes-AMG has dramatically honed the driving dynamics and looks further. For improved performance with significantly reduced fuel consumption, the AMG 4.0-litre V8 biturbo engine with cylinder deactivation replaces the previous 5.5-litre V8 biturbo. Despite the smaller displacement, the new engine puts out 450 kW (612 PS) and thus exactly 20 kW (27 PS) more than the preceding model. With a sprint time of 3.5 seconds from nil to 100 km/h, the performance luxury saloon is on par with thoroughbred sports cars. The AMG SPEEDSHIFT MCT 9‑speed sports transmission replaces the previous 7-speed gearbox. This has enabled more agile response times to be achieved. The fully variable AMG Performance 4MATIC+ all-wheel-drive system provides optimal traction.
The AMG 4.0-litre V8 biturbo engine in the S 63 4MATIC+ 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 nil 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).
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, an immediate response from the turbochargers and low exhaust emissions thanks to optimum airflow to the close-coupled catalytic converters. Two twin-scroll turbochargers provide even better fresh-mixture cylinder charge. The results are a higher output, more torque already at low engine speeds, and a very spontaneous throttle response.
