Performance and Engineering Excellence
At the heart of the Mercedes Sl63 lies the handcrafted AMG 4.0L V8 biturbo engine, a powerhouse of performance engineering.

Further enhancing the driving dynamics is the AMG ACTIVE RIDE CONTROL suspension. This 4-wheel independent system, featuring 5-arm multilink front and rear setups, adapts to road conditions and driving style, providing a perfect balance between comfort and sporty responsiveness. The rack-and-pinion steering with electromechanical power assist and 2.5-degree rear-axle steering contributes to the SL 63’s agile handling and precise cornering, with a turning circle of 40.7 feet (wall to wall).
