Cycle & Carriage - The SLS AMG Roadster

Uninterrupted power transmission

The design principle for the SLS AMG Roadster transmission has its origins in motorsport. It consists of two sub-transmissions, each equipped with a clutch. When changing gear, one clutch is engaged as the other is opened. This ensures that there is no loss of tractive power. Feel the excitement of the AMG SPEEDSHIFT DCT 7-speed sports transmission.

AMG SPEEDSHIFT DCT 7-speed sports transmission

The transmission system is located in a transaxle position at the rear axle and features a rigid link to the engine via a torque tube. Four drive modes and a Race Start function deliver the perfect response to changing road conditions and sporting ambitions.

Key details at a glance:

Aligned with engine performance: A double-clutch transmission delivers optimum transmission ratio adjustment through a closer spacing of individual gears even at high engine speeds
Optimum road-holding: An integrated mechanical differential lock delivers outstanding traction
Lightweight: The sports transmission weighs a mere 136 kg
When gear changes become a pleasure: Real metal shift paddles are used to move up and down the seven gears in the "M" transmission mode. A short pull on the left (–) or right (+) shift paddle is enough to select the required gear.
The choice is yours: Drivers can select from four transmission modes (ranging from "comfort" to "extremely sporty") as well as a Race Start function.
Shift up at full load: Experience dynamic acceleration for maximum driving enjoyment.
