AMG might be most famous for shoehorning big engines into luxurious saloons and SUVs to endow them with supercar-bothering acceleration, but let’s not forget they also build two-seat sports cars.
Unsurprisingly, the Mercedes-AMG GT Roadster has a stonking twin-turbocharged 4.0-litre V8 engine under the bonnet. It's available in a range of power outputs; while the regular GT Roadster gets 469bhp, the GT S boosts this to a very wholesome 515bhp, with the GT C pumping out 549bhp. At the top of the tree is the GT R with a mighty 569bhp.
Regardless of power output, the V8 drives the rear wheels only, though a seven-speed dual clutch automatic gearbox. All variants get a limited-slip differential, with GT S models and above getting an electronically controlled version. All that means even the slowest GT Roadster can rattle off the 0-62mph sprint in a mere 4.0sec and reach 188bhp.
However impressive those numbers are, the GT Roadster has a stern fight on its hands. Not only does it have the Porsche 911 Cabriolet to contend with, there’s also the Audi R8 Spyder. The pricier versions also tread on the toes of the McLaren 570S Spider.
