The rear end features numerous, conspicuous innovations. The aluminium side walls of the AMG GT C Roadster widen the open-top two-seater by 57 millimetres compared to the AMG GT Roadster. The muscular form also creates space for the larger wheels and a wider track. Both measures make for traction while allowing higher cornering speeds. The likewise wider contours of the AMG GT C Roadster's rear apron also improve airflow with their large outer air vents. Both Roadster variants feature an aerofoil integrated into the boot lid.
