S tronic 7-speed dual-clutch transmission

The S tronic combines the comfort of an automatic with the sportiness of a manual gearbox – and it does so with extreme efficiency.

The S tronic comprises two clutches: if you accelerate in second gear, for example, third gear is already preselected in preparation. When the ideal shift point is reached, the twin multi-plate clutch reacts in a flash: the first clutch opens while the other closes immediately. The gear change is completed within just a few milliseconds without any noticeable interruption in the power flow.
