Summary
The the Mercedes-AMG GT Roadster was a two-door high-performance convertible – a drop-top derived from the GT Coupé, and Mercedes’ answer to the Porsche 911 Cabriolet.
The GT Roadster arrived about two years after the GT Coupé at the end of 2016, and was discontinued in 2023 ahead of an all-new model launching in 2024.
The standard GT Roadster was around 50kg heavier than its coupé sibling, but used the same twin-turbocharged 4.0-litre V8 engine. Mercedes-AMG tuned the engine to produce a slightly higher output of 475hp, to counteract the added weight.
Due to this added weight, and the structural disadvantages that come with opting for a convertible, Autocar came to the conclusion that “the GT Roadster doesn’t quite match the GT coupé for outright cornering prowess or overall ride control”, and said that “it can be difficult to manoeuvre around tight spaces due to its elongated bonnet and poor rear vision.”
Auto Express added that the Porsche 911 Cabriolet was the more practical choice for day-to-day travel, though it also explained that the Mercedes-AMG matched the Porsche’s driving dynamics and ride comfort, “but feels more dramatic”, with an “intoxicating” V8 engine soundtrack.
“The 911 wishes it had this much personality”, Parkers asserted, praising the GT Roadster for its attractive muscle car exterior styling, its luxurious interior trim and its electrically-operated soft-top roof that opened or closed in 11 seconds.
As of May 2024, the Mercedes-AMG GT Roadster holds a Used Car Expert Rating of E, with a score of 52%. Although it scores well in media reviews, running costs are very high – which drag down our used car scores. We also don’t have reliability or safety data for this model.

“On the right road and at a well-chosen pace, the car’s got grip, composure and immediacy to spare – and the chassis provides a fine canvas on which to daub the luridly colourful brushstrokes of that wonderful V8 engine.”

Model reviewed: GT
Score: 8 / 10
“Although its responses are not quite as intense or as enthralling as its fixed-roof sibling, it is nevertheless as involving and absorbing as any rival convertible over any given road. It is also very close on overall ability and appeal to the significantly dearer GT C Roadster.”

Model reviewed: GT C
Score: 9 / 10
“I’d want to try a coupé with these revisions before saying whether or not it has the measure of a 911. I suspect the narrower, lighter Porsche would still be the better sports car. But remove the roofs of the two and the cars’ slightly different remit puts the argument in a different light. In terms of sound and drama, the GT would have it covered.”

Score: 8 / 10
“There’s no doubt the AMG GT S drives like the bespoke sports car that its exotic ingredients and layout suggest it should, and the facelift’s relatively superficial upgrades only enhance that appeal.”

The Telegraph
Model reviewed: GT C
Score: 8 / 10
“Despite pretensions of high-tech performance, the Mercedes-AMG GT Roadster is a deliciously unreconstructed muscle car, where ride and comfort take a back seat to all-out performance. Don’t get carried away with muscle for this muscle car, however; the lower-powered standard car is better balanced and a nicer drive.”
