After the huge success of the AMG GT coupe, Mercedes has launched the AMG GT Roadster convertible to take on the likes of the Porsche 911 Turbo Convertible, Jaguar F-Type SVR and the Audi R8 Spyder.

The AMG GT Roadster is a convertible version of the GT hardtop coupe. Normally, turning a coupe into a convertible hampers a car’s handling because only the car’s floor – not the roof in addition – holds the front and rear together. To counteract this effect, Mercedes has added extra reinforcement to the car’s structure. Despite this, only 65kg has been added to the overall weight of the vehicle compared to the coupe – impressive when you consider that includes the heavy electrically operated roof.

This ever-so-slight weight gain, combined with the standard AMG GT’s turbo V8 engine, blasts the roadster from 0-62mph in just four seconds – exactly the same as the coupe while topping out at 188 mph. Even if you drive the cars back-to-back, it’s unlikely you’d be able to notice the fractional reduction in rigidity between the coupe and convertible – instead it simply displays the same grip, adjustability and ferocious performance found in the hardtop.

If this plentiful performance still isn’t enough for you, there’s the AMG GT C Roadster. It uses the same 4.0-litre V8 but with 557hp instead of the standard car’s 476hp. This more closely rivals Porsche and Audi competitors by knocking three tenths off the Roadster’s 0-62mph time and raising the top speed to a dizzying 196mph. That’s just 0.1 seconds slower to 62mph than the all-wheel drive Audi R8 and faster flat out than the more powerful F-Type SVR.

The Porsche 911 Turbo is faster to 62mph from rest by 0.6 seconds which might seems like a lot but, in the real world, is almost completely irrelevant. Focussing solely on acceleration in a convertible is like going to the opera and only concentrating on what the singer is wearing – it’s sort of missing the point.

The AMG GT Roadster is one of the most rounded supercars on the market at the moment and makes you feel special every time you drive it. The swathes of leather and metal inside along with the meaty rumble from the engine are made even more pleasant with the roof down, adding to the sense of occasion – not to mention its handsome looks. This, all wrapped up in a package that costs from £110,115 – more than £27,000 cheaper than the Porsche – makes it seem like a no brainer.
