Stuttgart - When the Roadster version of Mercedes-AMG’s GT sports car was first announced back in 2016, the company elected not to offer an ‘S’ version, rather leaving customers to choose between the 350kW base model and the more brutal GT C with 410kW and various performance parts from the GT R.

However, AMG has now decided that it is a gap worth plugging.

Just like the Coupé version, the GT S Roadster gets various engine, suspension and design modifications to distinguish it from the base GT, with the 4-litre twin-turbo V8 tuned to 384kW and 670Nm. 

This is enough, says Mercedes-AMG, to shoot from 0-100km/h in 3.8 seconds, and reach a top speed of 308km/h.

Power goes to the rear wheels through an AMG Speedshift seven-speed dual-clutch transmission, and the GT S also features a sportier suspension set-up, complete with adaptive damping as standard, and there's an electronically controlled locking rear diff.

As with the tin-top, the Roadster has an aluminium-intensive body and structure, while the three-layered soft-top roof is supported by a lightweight structure of magnesium, steel and aluminium.

Says Mercedes-AMG Chairman Tobias Moers: “With the AMG GT S Roadster, our AMG GT family has gained another exceptionally sporty member that combines high driving dynamics with an emotional open-air experience.

"The new model represents the perfect alternative for the performance-oriented AMG GT Roadster customer."
