Mercedes-AMG blows the tops off its AMG GT family by introducing the new Mercedes-AMG GT Roadster and the new Mercedes-AMG GT C Roadster. Shortly after the world premiere of the hardcore AMG GT R, the Affalterbach based brand presents two roadster variants of the two-seater sports car. Lets get things started with the roof, or the lack on one. Both Roadsters a fabric roof that opens and closes in around eleven seconds, and can do this at speeds of up to 50 km/h. The three soft top colours black, red and beige can be chosen to suit the eleven exterior and ten interior colours.

While the AMG GT Roadster has an output of 476 hp and 630 Nm of torque from its twin-turbocharged 4.0-litre V8 engine, enabling it to accelerate to 100 km/h in 4.0 seconds and on to a top speed of 302 km/h, the AMG GT C Roadster is tuned to produce 557 hp and 690 Nm of torque from the same engine. This makes the AMG GT C Roadster’s peak output 47 hp more that of the AMG GT S and 28 hp less than the Mercedes-AMG GT R. Thus, a sprint from zero to 100 km/h is absolved in 3.7 seconds in the AMG GT C Roadster, while its top speed is rated at 316 km/h.

Both the Roadsters come equipped with the AMG SPEEDSHIFT DCT 7-speed automatic transmission, with the sportier AMG GT C Roadster featuring slightly altered gear ratios. While both are also available with the AMG DYNAMIC SELECT controller with three transmission modes “C” (Comfort), “S” (Sport), “S+” (Sport Plus) and “I” (Individual),  the Mercedes-AMG GT C Roadster gets an additional “RACE” mode. 

Other technical highlights of the Roadsters include the variable AMG performance exhaust system,  AMG DRIVE SELECT driving modes, active aerodynamics, AMG sports suspension with AMG RIDE CONTROL, active rear axle steering (both exclusive to the Mercedes-AMG GT C Roadster), and an electronically controlled locking differential at the rear axle (Mercedes-AMG GT Roadster: mechanical locking differential). Of course, there’s a more rigid body structure in place, which is achieved by the usage of aluminium alloys for the chassis/body, magnesium for the front deck, along with  additional struts, a strut tower brace and cross-members.

Visually, the Roadsters can be differentiated from their hard topped siblings with their AMG Panamericana grille with 15 chrome-plated, vertical bars, a new front apron, larger outer air inlets, along with the new 19-inch and 20-inch AMG light-alloy wheels in a 5-twin-spoke design. The rear end of the AMG GT C Roadster is wider by 57 mm compared to the AMG GT Roadster. This is exactly the width of the AMG GT R. Compared to the AMG GT Roadster, the AMG GT C Roadster also gets larger wheels and a wider track. Both Roadster variants feature a rear spoiler integrated into the boot lid. This is electrically extended and retracted at defined speeds, depending on the selected transmission mode.

The interiors are reminiscent of the coupe, while being trimmed in nappa leather. The cabin’s highlight are the optionally available AMG performance seats, also optionally available with the AIRSCARF neck-level heating system. Then there’s the  Burmester surround sound system and the Burmester high-end surround sound system. Both systems, developed jointly by AMG and Burmester feature the Externed Coupled Subwoofer (ECS), which does away with a  subwoofer box, and uses the entire interior as a bass box. This is made possible by a special aperture in the right rear wheel arch, and the subwoofer is connected to the bodyshell via this aperture. Additionaly, the AMG GT C Roadster is also equipped with a lithium-ion battery, and has more exclusive appointments like the AMG performance steering wheel in nappa leather/ microfibre.
