Prices revealed for Mercedes-AMG GT and GT C Roadsters
New Mercedes-AMG GT Roadster to start from £110,145, with more powerful GT C Roadster kicking off from £139,445
Introducing two roadster variants means that the AMG GT line-up is now five models strong. Both of these new models pack more power and torque than their equivalent hardtop versions, and borrow chassis technology from the hardcore AMG GT R.
The AMG GT Roadster is on sale now, starting at £110,145, while the more powerful GT C version kicks off at £139,445.
The entry AMG GT Roadster develops 469bhp and 630Nm of torque from its 4.0-litre twin-turbo V8, which is 13bhp and 30Nm more than the hardtop. Above that sits the AMG GT C Roadster, with a full 549bhp and 680Nm – that puts it between the 503bhp GT S coupe and 577bhp GT R. All AMG GT models use Merc’s seven-speed dual-clutch automatic gearbox.
The power bumps mean that the AMG GT Roadster is capable of 0-62mph in four seconds flat – identical to the hardtop – while the GT C Roadster does the same sprint in 3.7 seconds, one-tenth quick than the S coupe. Top speeds are claimed at 188mph and 196mph respectively.
Merc has opted to fit a three-layer fabric soft-top over a folding hardtop – like that on the SL – to keep weight down. However, Mercedes has had to add strengthening to compensate for the lack of a fixed roof meaning the base Roadster weighs 55kg more than its hardtop equivalent. The GT C is 90kg heavier than the GT S. The frame of the roof is supported by a mixture of aluminium, steel and magnesium, and folds electrically in eleven seconds at up to 31mph. The roof can be ordered in black, red or beige, while rollover bars and an aluminium cross-member have also been added for safety.
The main body structure of the AMG GT Roadster is strengthened with extra bracing throughout, while the bootlid is constructed from a new composite material. Both Roadster models also adopt tech from the track-focused AMG GT R that the AMG GT coupes don’t benefit from. This includes active aerodynamics, with vertical louvres behind the grille opening and closing to boost cooling or reduce drag. Both cars also benefit from tweaked exterior styling, with a new Panamerica 15-bar grille borrowed from the GT3 racing car, plus revised air intakes and new alloy wheel designs.
The GT C takes things a step further, though, with a wider track and rear arches mimicking the GT R. It also borrows chassis tech, with active rear steering and an electronically controlled limited-slip diff claiming to boost agility. AMG’s adaptive dampers, a retuned dual-clutch transmission with new Race mode, and a switchable performance exhaust complete the raft of additions for the AMG GT C.
Mercedes has also tweaked the interior. There’s a new light-coloured leather option, while the optional AMG performance seats gain the brand’s Airscarf system which blows hot air over the occupant’s necks. A revised Burmester sound system also gains a new bass sound reproduction system.
Buyers of the standard AMG GT Roadster can step up to Premium equipment line for an extra £4,195. This includes the Burmester sound system, as well as keyless-go, door sill panels in stainless steel with AMG lettering and Merc's Parktronic system with reversing camera, all of which is standard on the GT C Roadster.
