Heart of the motorsport
The 963 RSP is powered by a 4.6-liter V8 biturbo with around 680 hp. Known internally as the 9RD, the engine is based on the power unit of the 918 Spyder, which in turn inherited it from the successful RS Spyder. And this also competed under the Penske flag in a US racing series known at the time as the “ALMS”. An electric motor supplements the familiar but very powerful engine, the hybrid system delivers up to an additional 50 kW and works with 800-volt technology.
