The engine weighs 135 kg (298 lb) according to Porsche and delivers 608 PS (600 hp; 447 kW) at 8,600 rpm and 530 N⋅m (391 lbf⋅ft) of maximum torque at 6,600 rpm. This is supplemented by two electric motors delivering an additional 210 kW (286 PS; 282 hp). One 115 kW (156 PS; 154 hp) electric motor drives the rear wheels in parallel with the engine and also serves as the main generator. This motor and engine deliver power to the rear axle via a 7-speed gearbox coupled to Porsche's own PDK double-clutch system. The front 95 kW (129 PS; 127 hp) electric motor directly drives the front axle; an electric clutch decouples the motor when not in use. The total system delivers 887 PS (652 kW; 875 bhp) and 1,280 N⋅m (944 lbf⋅ft) of torque. By October 2012, the engineering design was not finalized, but Porsche provided performance figures of 0–100 km/h (0–62 mph) in 2. 5 seconds, 0–200 km/h (0–124 mph) in 7. 2 seconds, 0–300 km/h (0–186 mph) in 19. 9 seconds and a tested top speed of 350 km/h (217 mph). The Porsche 918 Spyder has a power to weight ratio of 1. 93 kg (4. 25 lb) per horsepower, and the Weissach Package-equipped car has a power to weight ratio of 1. 85 kg (4. 08 lb) per horsepower.
