Although Mercedes-Benz has yet to confirm whether or not the upcoming AMG GT sports car will get a roadster version, it would be plain silly for the Germans to skip on a drop-top. I mean, why take the Porsche 911 Turbo by the horns and completely ignore the Turbo Convertible? It would be right given the competitiveness of today’s sports car market.
That said, an AMG GT Roadster launch is likely to occur sometime next year, a few months after the Coupe version goes on sale. Testing will probably commence later this year, but not before the Stuttgart crew rounds off the hard-top version, which was already spotted on both public roads and at the Nurburgring track on several occasions .
Since the coupe and roadster will share the same underpinnings, development of the latter will have a more smoother path, with engineers needing only to take care of additional structural reinforcing - a standard procedure for just about any convertible.
No changes will occur under the hood, where the same turbocharged, 4.0-liter, V-8 engine will gurgle with at least 500 horsepower at its disposal while sending it to the wheels via a seven-speed, dual-clutch transmission. A minor decrease in top speed is likely though, with a few mph chopped off the coupe’s estimated 190 mph.
Updated 09/10/2014: Now that we have seen the official pictures of the all-new AMG GT it gets pretty easy to imagine how the roadster version will look like. Check out our new rendering to see it for yourself.

Design-wise, and aside from losing its fixed roof, the Mercedes-Benz AMG GT will gain a slightly longer trunk. This minor tweak will allow for a smoother transition from one body style to the other without ruining the car’s sleek appearance. Naturally, a panel will be used to fill the gap behind the seats, while a wind deflector will show up between the headrests.
Porsche offers the 911 Turbo Cabriolet in two guises, both powered by the familiar 3.8-liter inline-six, but with different outputs on tap. The standard 911 Turbo boasts 520 horsepower and 487 pound-feet of torque and needs 3.3 seconds to sprint from 0 to 60 mph on its way to a top speed of 195 mph. Moving over to the Turbo S, the brawnier drop-top comes with 560 horsepower and 516 pound-feet of torque, which translates into a 0-to-60 mph acceleration time of only 3 seconds. Top speed also sees a slight improvement, jumping from 195 mph to 197 mph.
Mercedes-Benz will be looking to offer matching rivals for the 911 Turbo and 911 Turbo S as well, but with no performance figures available, it remains to be seen who will win Stuttgart’s power war. Moving over to the interior, the AMG GT and the 911 Turbo are pretty much on par, with both vehicle benefiting from exquisite amenities and the latest technologies.
Pricing for the AMG GT is still unknown, but the Porsche 911 Turbo Convertible retails from $160,700, while the Turbo S is priced from $193,900.
Unlike the 911 Turbo and the AMG GT, the Audi R8 V10 Spyder sports a larger, 5.2-liter V-10 engine under the hood. But bigger displacement and more cylinder doesn’t necessarily mean a lot more power. The Audi benefits from 525 horsepower and 391 pound-feet of torque, and although it has a few more horses than the 911 Turbo, it sits bellow the Turbo S and will have the same position against the range-topping AMG GT.
The R8 V10 Spyder need about 3.7 seconds to accelerate from naught to 60 mph when equipped with the seven-speed S-tronic transmission, while the manual gearbox will increase the sprint to about 4 seconds. Top speed sits at 193 mph with the former and 194 mph with the latter. The vehicle’s interior might not seem as flashy when compared to its rivals, but the R8 comes with plenty of luxury and convenience features and a long list of options. Pricing for the V-10-powered model begins at $164,000.
