What is it?
It’s a Mercedes-AMG GT without a roof. It’s called the GT Roadster, unsurprisingly, and it’s tested here in an all-new ‘C’ specification, which sits between the GT S, which is quite fast, and the all-mouth and also all-trousers GT R, which is extremely fast.
That broadens out the GT range to quite a few models now, possibly confusingly, so here’s the simplified rundown. You can get a GT as a coupé and a roadster. All have a 4.0-litre V8 but the angriness of the car and engine package varies. There’s the standard GT, with a mechanical limited-slip differential and 469bhp. Then there’s the GT S, which gets an electronically controlled limited-slip differential and 515bhp. At the moment, this is a coupé only, but a roadster version will come.
Now there’s the GT C, which looks more like the very angry R model (more of which below) and gets that car’s wider bodywork and wider track, plus rear-wheel steering and a power output of 550bhp. At the moment, the GT C is available as a roadster only (the car I’m testing here), but a coupé will follow.
And then there’s the GT R: the Porsche 911 GT3 of the Mercedes-AMG GT range, if you like. This has all kinds of angriness and 576bhp and is currently a coupé only (but that might change). The designs of both coupé and roadster versions of the GT have been updated to look more like the R model, which means they get the prominent ‘Panamericana’ grille.
