Mercedes finally pulled the wraps off the AMG GT’s Roadster version which will come in two flavors: the basic 469hp model and the range-topping 547hp GT C model.
The rumors were true then, as the new AMG GT C Roadster not only offers 46hp more than the AMG GT S Coupe but also borrows some of the technology found in the manic AMG GT R.
More specifically, the new AMG GT C comes with the GT R’s rear axle steering, electronic locking differential and a wider rear track. Torque is rated at a peak 501lb-ft (680Nm), available from just 1900rpm. Mercedes reckons it needs 3.7 seconds to hit 62mph from a standstill, with the top speed electronically limited to 196mph (316km/h).
The AMG GT Roadster on the other hand requires 4 seconds flat for the 0-62 procedure and won’t stop accelerating before hitting 187mph. Both models are powered by the same twin-turbo 4.0-litre V8 engine that has become the spine of AMG’s range, powering almost everything wearing their badge. As in the Coupe, a seven-speed dual-clutch automatic is the only transmission option.
The fabric roof opens and closes in just eleven seconds, up to speeds of 32mph (50km/h). The company will offer customers a choice of three colors for the soft top (black, red and beige), eleven color options for the exterior and ten for the cabin. The structure of the three-layered fabric top is made out of a combination of magnesium, steel and aluminum to keep the weight down.
Speaking of which, the AMG GT Roadster tips the scales at 1,595kg, with the GT C Roadster weighing 65kg more, at 1,660kg. AMG’s engineers have also fiddled with the latter’s seven-speed DCT gearbox, giving it a higher first gear, a lower seventh gear and final ratio to make it more responsive, and an extra transmission mode called ‘Race’. This one adjusts the shift strategy for maximum attack on a racetrack, making the gearbox change cogs faster and the engine produce a ‘highly emotive sound’.
Both versions of the new AMG GT Roadster borrow the active air management system from the GT R. Vertical louvres behind the front fascia can be opened or closed by an electric motor, adjusting the cooling performance and airflow to need. The AMG Panamericana front grille features 15 chrome-plated vertical bars, underlining the company’s racing heritage.
The new Mercedes AMG GT Roadster and GT C Roadster will make their public debuts at the Paris Motor Show.
