Like the vaunted 300 SL 'Gullwing' of the 1950s, Mercedes-AMG's GT Coupé has taken very well to roadster duty. Mercedes has kept things reasonably simple with a folding fabric soft top that retracts in 11 seconds at speeds as high as 30mph.
Both versions make use of a twin-turbo 4-litre V8 engine matched to a seven-speed dual-clutch automatic transmission. But while the standard car rolls with 469 horsepower, the wide-body version GT C packs a healthy 549 horsepower. The C model borrows some key components from Mercedes-AMG's track-ready GT R Coupé; the company promises the car will make the sprint from zero to 62mph in 3.7 seconds and push all the way to a top-down top speed of 196mph.
The C, pictured here, features wider wheels and a track expanded by 57mm, with broader bodywork to accommodate. Merc engineers have gone to great lengths to offset the weight penalty of roadster-isation, substituting magnesium, aluminium and carbon-fibre-infused sheet moulding compound for steel wherever possible. As such, the GT Roadster is a modest 55kg heavier than the standard GT Coupé, and the more loaded GT C is a slightly less-modest 90kg more than the sportier GT S Coupé (and 105kg more than the hardcore GT R Coupé).
The company has not yet released pricing for its topless twosome, but it is safe to expect the GT Roadster will command upwards of £110,000 and the GT C Roadster will top that figure by at least £20,000.
