The Porsche 918 Spyder has a combined system output of 887 PS.
That figure comes from a plug-in hybrid powertrain combining a 4.6-litre naturally aspirated V8 with two electric motors. Porsche rated the petrol engine at 608 PS and the electric motors together at 286 PS, producing a system total of 887 PS, or 652 kW.
The numbers are sometimes confused because horsepower units differ by market. Porsche commonly quotes 887 PS, while the equivalent imperial figure is about 875 hp. The total is also a system-output figure: it describes the coordinated maximum output of the combustion engine and electric motors rather than simply adding ratings that are always available simultaneously.
The 918’s hybrid layout was designed for both efficiency and extreme performance. Its electric front motor also provided all-wheel drive, while the rear electric motor worked with the V8 at the rear axle.
