The folks over at Affalterbach have unveiled the new Mercedes-AMG AMG GT S Roadster, a 384 kW open-top derivative that slots into the gap between the 350 kW GT Roadster and the 410 kW GT C Roadster.

Like its topless siblings, the new AMG GT S Roadster employs Mercedes-Benz's familiar twin-turbo 4,0-litre V8 engine mated to a seven-speed dual-clutch transmission, but in this application tuned to deliver 384 kW and 670 N.m.

The sprint from standstill to 100 km/h takes a claimed 3,8 seconds (just one-tenth slower than the GT C Roadster), while top speed comes in at 308 km/h (eight units down on the flagship Roadster).

The AMG GT S Roadster features adaptive damping, an electronically controlled locking rear differential, 19-inch front and 20-inch rear ten-spoke light alloys, and an AMG high-performance composite braking system (390 mm front and 360 mm rear discs) as standard. Meanwhile, ceramic composite brakes (402 mm front and 360 mm rear discs) are offered as options.

Inside, the AMG GT S Roadster is fitted as standard with the “silver chrome interior” package, which includes silver treatment for the centre console surround, air-vent bezels and trim strips in the door armrests.
