New Mercedes-AMG GT Roadster And GT C Roadster
Mercedes-AMG reveals the core strengths of its new, open top, sports cars.
AMG GT Coupé range gains soft-top siblings
The Mercedes-AMG GT Roadster and GT C Roadster are new, open top, versions of the brand's most prestigious sports car; the GT. Siblings include the: GT Coupé (462hp), GT S Coupé (510hp) and the GT R Coupé which is the hard-core, track-focussed, version (585hp).
Engines, 0-62mph times and top speeds
The GT Roadster is the slightly tamer of the new variants. Power comes via a 4.0-litre, V8, twin-turbocharged, petrol engine that produces 476hp at 6,000rpm and 630Nm of torque between 1,700 and 5,000rpm. Expect 0-62mph in 4.0 seconds plus a top speed of 187mph.
AMG said: “The 8-cylinder engine thrills with its immediate response, linear finely controllable power delivery, and powerful acceleration in all rpm ranges.” Furthermore, the turbochargers sit in the centre of the V – between the 2 banks of 4 pistons, in other words - to optimise their responses and minimise exhaust emissions.
The Mercedes-AMG GT C Roadster builds on its bedfellows strengths so is even more powerful. Its 4.0-litre, V8, twin-turbocharged, petrol engine produces 557hp between 5,750 and 6,750 rpm. This power plant also generates 680Nm of torque between 1,900 and 5,750rpm. Expect 0-62mph in 3.7 seconds plus a top speed of 196mph.
The GT Roadster and GT C Roadster have 7-speed, dual clutch, automatic transmission. The AMG Dynamic Select Controller enables motorists to pick: Comfort, Sport, Sport Plus and Individual Modes to tweak its responses based on personal preference. Choose sportier, higher-rev, changes when fun is top of the list, perhaps.
The Mercedes-AMG GT C Roadster incorporates Race Mode too. As the name suggests, it optimises the response of the automatic transmission to suit a race track. “Very fast shift speeds and highly emotive engine sound are included”, the manufacture claimed.
The GT C Roadster has a performance exhaust and its flaps open/close to change its tone based on AMG Drive Select Settings. Sport Plus produces a more “emotive” sound, for example, whereas Comfort produces a low-frequency pulse most typical of a V8 engine.
The GT Roadster has sports suspension that provides “optimum, highly precise, road feedback right up to the very high cornering limits”, the manufacturer said. The GT C Roadster, in contrast, adds AMG Ride Control that tweaks the response of the dampers based on the prevailing “handling situation, speed, and road conditions”.
These Roadsters have other strengths too. Highlights include the:
- electric, fabric, roof that operates in about 11 seconds at up to 31mph and is available with a black, red or beige finish;
- muscular styling that incorporates a long bonnet, wide rear and striking alloy wheels;
- choice of 11 exterior and 10 interior colours.
