Mercedes-AMG GT C Roadster premieres ahead of Paris Motor Show image

The open top version of the AMG supercar will be on point for the worldwide audience during the Paris Motor Show, with not one but two versions coming to life at the same time.

We have the AMG GT Roadster that uses the same credentials as the hardtop brethren, albeit with a slightly tuned engine version and a raft of careful enhancements. On the other side though sits the cash-nabber AMG GT C Roadster with an almost as powerful version of the biturbocharged V8 engine as the hardcore GT R as well as certain tricks snatched from the latter. Both the GT and GT C Roadsters use the same AMG 4.0-liter biturbo V8, with 469 horsepower and 465 pound-feet of torque for the former – which is 13 hp and 22 lb-ft more than in the GT Coupe. This enables the convertible to sprint to 60 mph in just 3.9 seconds, just as fast as the coupe version.

The GT C then springs to life with 550 hp and 502 lb-ft to the table – up 47 hp and 23 lb-ft from the GT S Coupe, thus inching to 60 mph in the same 3.7 seconds. This slots it between the S and R versions and there’s also a GT C coupe version in the works. The AMG division reworked the seven-speed dual-clutch Speedshift transmission for the GT C and the model also has the AMG Performance Exhaust system. Additionally, it uses the active rear-wheel steering system from the GT R, and the rear fenders have been widened by two inches, to atone the wider track and bigger wheels. Mercedes didn’t say how much added weight comes from the convertible conversion, but claims the three-layer fabric top is supported by a lightweight structure, combining magnesium, steel, and aluminum.
