Thanks to the many photos we had received from our German spy snapper over the last few months, we knew the drop-top version of the Mercedes-AMG GT and a more hardcore GT C were close to being launched. Today, the German carmaker has revealed official photos and details of GT Roadster, based on the base AMG GT and the GT C Roadster, which is powered by a more powerful version of the Merc-AMG biturbo V8 engine.
In the GT C, the V8 churns out 550bhp and peak torque of 680Nm, naking it the most powerful roadster from the brand. The peak output is 47 horses more than that of the AMG GT S and just 27 horses less than the Mercedes-AMG GT R. It is capable of sprinting from 0-100kph in just 3.7 seconds on its way to a top speed of 316kph. Meanwhile the same 4.0-litre biturbo V8 block puts out 469bhp and 630Nm of torque in the AMG GT Roadster, which dispatches the 0-100kph dash in 4.0 seconds and hits a top speed of 302kph.
The seven-speed dual clutch transmission has been remapped to cope with GT C Roadster’s increased power output. The first gear has a higher ratio, while seventh gear and the final drive have a lower ratio, which Mercedes says has improved throttle response siginificantly. While the AMG GT Roadster’s Dynamic Select controller let the driver choose between three transmission modes, Comfort, Sport, Sport Plus and the programmable Individual, the GT C Roadster adds a Race mode to it. This mode optimally adjusts the transmission to suit driving on a racetrack.
The new Roadster variant also uses many technical bits from the wild AMG GT R. These include active rear axle steering, and the electronically controlled rear axle locking differential. It also gets the AMG Ride Control sport suspension, wider rear fenders, a wider track and wider wheels at the rear axle and a variable performance exhaust system.
The three-layered fabric roof opens and closes in around 11 seconds, and can do this at speeds of up to 50kph. Three colour options (black, red and beige) are available for the roof to go with 11 exterior and 10 interior colour choices.
“With our two Roadster models, we are strategically expanding the AMG GT family by two exciting variants. With the AMG GT C Roadster, we are also introducing a new model variant to which we have transferred main performance-related components from our top sports car, the AMG GT R. The result: a highly dynamic driving experience in a very exclusive ambience, coupled with that pure roadster feeling,” says Tobias Moers, chairman of Mercedes-AMG GmbH.
Both versions of the AMG GT Roadster will debut at the Paris Motor Show later this month.
