Mercedes-AMG GT R Roadster arrives as 197mph soft-top


The Mercedes-AMG GT Roadster has spawned a limited-run, hardcore R variant to top the convertible sports car’s range. 

Revealed at the Geneva motor show and limited to just 750 units, the Mercedes-AMG GT R Roadster will share its twin-turbocharged 4.0-litre V8 engine with the GT R coupé, producing 577bhp and 516lb ft and hooked up to a seven-speed dual-clutch gearbox.

It can crack 0-62mph in just 3.6sec, and reach a top speed of 197mph. That 0-62mph time matches that of the GT R coupé, and the top speed is just 1mph shy of its fixed-roof sibling.

The aggressive styling of the coupé also translates to the Roadster, including the large fixed rear wing, while the likes of the coil-over suspension and adjustable dampers, tuneable through several different driving modes, and rear-wheel active steering feature, too, to give the GT R Roadster a very similar dynamic spec to the coupé.  

The aerodynamic package also carries over, including the front lip spoiler, active aero front grille and large rear double diffuser that houses the exhausts. The wider track over the GT C Roadster on which the car is based allows for the larger lightweight 19in front/20in rear alloys shod in Michelin Pilot Sport Cup 2 tyres sized 273/35 front and 325/30 rear to be fitted to the GT R Roadster, and improves stability, too.
