Mercedes-AMG GT C Roadster revealed ahead of Paris debut

We knew this was coming. The Mercedes-AMG GT Roadster will drop its top at the Paris Motor Show later this month, with two models launching simultaneously. The AMG GT Roadster builds upon the base version of the hardtop model, adding a bit more power and a few new features. But it's the AMG GT C that'll really grab your attention – it features a more powerful version of the biturbocharged V8 engine, and brings with it some trick features from the super-hardcore AMG GT R.

 

Both GT and GT C models use AMG's outstanding 4.0-liter biturbo V8. In the GT Roadster, 469 horsepower and 465 pound-feet of torque are available – increases of 13 hp and 22 lb-ft over the GT Coupe. That's not a huge bump, sure, but it means the roadster can run to 60 miles per hour in the same 3.9 seconds of its hardtop sibling. The GT C, on the other hand, brings 550 hp and 502 lb-ft to the table – that's 47 hp and 23 lb-ft more than the GT S Coupe, delivering the same 3.7-second 0-60 time.

 

Mercedes remapped the seven-speed dual-clutch Speedshift transmission for the more powerful tune of the GT C. First gear now has a higher ratio, while seventh gear and the final drive have lower ratios. The GT C also comes with Merc's AMG Performance Exhaust system, which we're sure sounds freaking awesome. What's more, the GT C uses the active rear-wheel steering system from the GT R, and the rear fenders are more than two inches wider, to account for the wider track and larger wheels.

 

It's unclear exactly how much weight the soft top mechanism adds to the GT's body, but Mercedes stresses that the three-layer fabric top is supported by a lightweight structure, combining magnesium, steel, and aluminum. The top comes in three colors (beige, black, and red), and can be operated at speeds up to 31 mph.

 

Pricing will be confirmed closer to the convertibles' arrival at U.S. dealers in about a year from now – "fall 2017," says Mercedes.
