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 V-8 Biturbo engine with cylinder deactivation replaces the previous 5.5-litre V-8 Biturbo. Despite the smaller displacement, the new engine puts out 450 kW (612 hp) and thus exactly 20 kW (27 hp) more than the preceding model. With a sprint time of 3.5 seconds from zero to 100 km/h, the performance luxury saloon is on par with full-blooded 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.
