It is believed the prototype is a derivation of the V4 engine that was run in the Porsche 919 Hybrid - the dominant Le Mans racer that was later unshackled and set the outright Nurburgring lap record.
The V4 in the 919 Hybrid was a 2.0-liter, 90-degree four-cylinder with a single turbo producing circa 500 horsepower in standard trim and as much as 720 hp when fully unleashed.
