Mercedes’ AMG GT family is growing, with the introduction of a roadster variant for the desirable 2-seat sports car.
The new roadster comes in two iterations — the Mercedes-AMG GT Roadster and GT C Roadster — with the latter harnessing some of the qualities of the AMG GT R to become the most powerful roadster ever in the Mercedes family (featuring outputs of 550 hp and 502 lb-ft of torque). The GT Roadster version of the 4.0-litre twin-turbo V-8 puts out 469 hp and 465 lb-ft.
“With our two Roadster models, we are strategically expanding the AMG GT family by two exciting variants,” says Tobias Moers, Chairman of Mercedes-AMG GmbH. “With the AMG GT C Roadster, we are also introducing a new model variant to which we have transferred main performance-related components from our top sports car, the AMG GT R. The result: a highly dynamic driving experience in a very exclusive ambience, coupled with that pure roadster feeling.”
Other GT R features include rear steering (which turns the rear wheels opposite the front at speeds up to 100 km/h and in the same direction at speed above that) and a rear locking differential, as well as pushed out rear fenders to create more room for wider rear track and a wider rear wheel/tire combination (20-inxhwea with 305/30 tires). Also on board is the AMG Ride Control sport suspension for improved dynamic performance. Finishing it off, the V-8 exhaust note is enhanced through the variable AMG Performance Exhaust.
Performance-wise, the GT Roadster gets to 100 km/h in just under four seconds, with the GT C Roadster doing it slightly faster in 3.7. Top speeds are limited to 302 km/h and 315 km/h, respectively.
Both versions are equipped with the AMG Speedshift 7-speed dual-clutch automatic transmission (the GT C also features a “Race” mode, in addition to Comfort, Sport and Sport-Plus).
For exterior looks, the two new models are unmistakably AMG GTs, but with electrically operated fabric tops (that reportedly go up or down in about 11 seconds, at speeds up to 50 km/h) to add the dimension of open top motoring. The bodyshell is rigid and light, made from aluminum, to limit the twisting forces common to convertibles when their tops are down. The 3-layered top comes in black, red or beige.
The body also features the active air management system from the GT R (with vertical louvres behind the front fascia that open and close to allow the needed cooling for the engine), and a deployable rear spoiler in the carbon-fibre deck lid.
Inside, there is extensive use of leather, with the GT C further featuring Nappa leather, including on the AMG Performance steering wheel that also has Dinamica microfiber inserts for a tighter grip. The optional AMG performance seats also feature the neck-warming Airscarf and cooling ventilation for the first time. Two Burmester sound systems cap off the premium driving experience in the new roadsters.
The new Mercedes-AMG GT Roadster and GT C Roadster are due in North America by Fall 2017.
