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.
The AMG SPEEDSHIFT MCT 7-speed sports transmission is an all-new, unique concept, available exclusively in the new Mercedes-Benz SL63 AMG. It combines the best of two worlds: the sporty, direct and agile feedback of a manual transmission and the maximum convenience of an automatic transmission.
Fitted with seven speeds, four drive modes, a double-declutching and Race Start function, the AMG SPEEDSHIFT MCT 7-speed sports transmission offers unprecedented versatility. MCT stands for Multi-Clutch Technology and only employs clutch elements to perform gearshifts.
The high-tech transmission is designed for high torque and maximum revs up to 7200 rpm. It also comes with sufficient reserves even under the highest loads thanks to its high-performance oil cooling system. An all-new, sophisticated electronic transmission control unit fully controls and monitors all processes.
A new two-stage torsion damper effectively eliminates vibrations. The AMG SPEEDSHIFT MCT 7-speed sports transmission has been developed jointly by Mercedes-AMG GmbH and Daimler AG, although it will be used exclusively in AMG high-performance vehicles. It is produced at the Mercedes-Benz Esslingen-Hedelfingen production facility, Europe’s largest manufacturer of planetary gear sets.
