The ‘R’ badge on Mercedes-Benz’s AMG GT came with more aero, more power, a bit less weight and a few batsh*t chassis mods. We’ve also seen what happens when the company chops the top off the GT R to create the GT R Roadster.

Until now, AMG seemed to be a bit reluctant in combing the GT R’s 577-hp engine and its open-top body style. However, ending all doubts the company has finally lowered the top on its mean sports car.

Both the Coupe and Roadster are evenly matched in terms of performance, despite the latter lugging more weight along.

On paper, the spec sheet is more or less identical to that of the standard GT R. With a foldable top, the GT R Roadster comes with an extra 46mm of girth from carbon fibre widebody panels. It outputs the same 577hp from the 4.0-litre Biturbo V8. Other notable features that add awe to the GT R Roadster include rear-wheel steering and a nine-stage traction control system.

You can witness triple-digit speeds in a brisk 3.6 seconds and a top speed of 317kph. Surprisingly, these are the same numbers as the Coupe posts. On the outside, the soft-top gets the same aggressive styling of the coupe such as the large fixed rear wing. The coil-over suspension and adjustable dampers can be tuned through several driving modes.

The interiors have been derived entirely from the Mercedes-AMG GT R.

Based on the GT C Roadster, the soft-top GT R comes with a wider track allowing for the larger lightweight 19-inch wheels wrapped in Michelin Pilot Sport Cup 2 tires.

The three-layered fabric roof from the rest of the GT Roadster range is derived in the GT R Roadster. The model scales at 1710kg, an increase of 80kg over its coupe sibling. Meanwhile, lightweight options include composite brakes and a two-stage carbon fibre pack for various trim elements.

Lowering the top on its GT R sure can be speculated as Mercedes-Benz’s concrete answer to the likes of its German rival Porsche, which has been largely gaining talks and numbers.
