For the extra power, engineers added a pair of twin Rotrex superchargers, which increased the pressure of air being fed to the engine. Additionally, the engine’s electronic management system was tweaked with a Motronics ECU and a wind-tunnel tested aerodynamic package with a new rear-spoiler was added. Acceleration figures remain much the same as the hardtop, with the 0-100km/h coming up in just 3.7 seconds and top speed climbing to 348km/h.
Other features of the package include a separated oil-circuit, a heat insulated induction tract, water-cooled intercoolers with water pumps and additional radiators, upgraded fuel injectors and reinforced drive belts with dynamic tensioners.
