Emotional performance courtesy of cutting-edge engineering: the new Mercedes-Benz SL63 AMG in a nutshell. The roadster is powered by an AMG 6.3-litre V8 engine developing 386 kW/525 hp and 630 Newton metres - which makes it today's most powerful model with a V8 naturally aspirated engine in its class. The Mercedes-Benz SL63 AMG comes exclusively with the all-new, innovative AMG SPEEDSHIFT MCT 7-speed sports transmission. The newly developed power transfer concept features a compact, wet start-up clutch that replaces the conventional torque converter. The resulting direct connection to the powertrain, together with the double-declutching and Race Start functions, guarantees an extremely emotional, supremely dynamic driving experience. The Mercedes-Benz SL63 AMG sets new standards in the open-top sports car segment thanks to this outstanding drive combination and the retuned, even more agile AMG sports suspension based on Active Body Control - turning it into the sportiest SL-Class ever. The new Mercedes-Benz SL65 AMG was launched alongside the Mercedes-Benz SL63 AMG.
