The seven-speed dual clutch transmission has been adapted in a transaxle arrangement at the rear axle to the new power level of the Mercedes‑AMG GT C Roadster by modifying the hardware and software. The first gear of the AMG SPEEDSHIFT DCT 7-speed sport transmission has a higher ratio, while seventh gear and the final drive have a lower ratio. The driver is able to set the AMG GT Roadster to his/her individual requirements using the AMG DYNAMIC SELECT controller.
Both Roadsters are quickly transformed from coupés to open-top sports cars. The fabric roof opens and closes in around eleven seconds, and can do this at speeds of up to 50 km/h. The three soft top colours black, red and beige can be chosen to suit the eleven exterior and ten interior colours. The three-layered fabric soft top is supported by a magnesium/steel/aluminium structure of low weight, which helps to keep the centre of gravity low. Additional rollover protection is provided by an integrated aluminium cross-member with rollover bars.
Extremely short braking distances, precise pressure point and outstanding fade resistance even in extreme operating conditions - the AMG ceramic high-performance composite brake system offers race-track braking performance accompanied by weight savings of around 40% over conventional composite brake discs.
The system offers an ideal combination of agility and stability ‑ handling characteristics that are normally in direct conflict. Up to a speed of 100 km/h, the rear wheels are turned in the opposite direction to the front wheels, the Roadster turns into corners with significantly higher agility as a result, delivering even more driving pleasure and requiring less steering input. In day-to-day driving the driver also benefits from a reduced turning circle, for example when turning off or parking. This option is only available for Mercedes-AMG GT C Roadster.
