The final tally, with the weight reduction, of the Carrera Club Sport was a lightweight 1180kg. The air-cooled 3.2L flat six engine was blueprinted at the factory and, apart from that process, the only change was to the hollow intake valves used in the head. The Digital Motor Electronics (DME ECU) was reprogrammed raising the rev limit by 500rpm. Although the engine was rated the same 231 hp (172.26kW) and 283 ft/lbs (3843.7Nm) of torque as the standard car, the CS was 0.5 seconds quicker to 60mph (96.56km/h) with horsepower being rumoured to be, in fact, more likely 250 (186.43kW). The quickest acceleration test of the day being 5.1 seconds 0-60mph (0-96.56km/h) with the Porsche rear engine design assisting with traction. Top speed was reportedly 151 mph (243.01km/h).
