Under the long bonnet of both cars is the 4.0-litre biturbo V8, well known both for its torque – 500 lb ft from just 1,900rpm in the C version – and its fruity sound effects, said to be taken to whizz-bang new levels for the C model’s Race mode.
Aside from performance and the C’s wider rear end, both the new Merc-AMG sports cars are essentially the same car – the GT with its roof replaced by an electric folding fabric top. Very smart it looks too we reckon. The three-layer hood takes 11 seconds to go up or down and can be operated at speeds up to 30mph – par for the convertible course in other words.
Monocoque structures need reinforcement when you lop off their tops and Mercedes’ aluminium GT body is no different. There are beefed-up body sides, additional struts to brace the dashboard and windscreen, an extra brace to reinforce the rear axle and a cross member behind the seats to support the rollover protection system. Magnesium (bonnet) and composites (boot) have been added to the aluminium to add strength and save weight.
