The heart and soul of every Koenigsegg is its Internal Combustion Engine – the ICE. The ICE of the Regera follows the path of its siblings, the proven and extremely reliable Koenigsegg dry-sump twin turbo, DOHC, 5.0 liter V8.

The Koenigsegg V8 is the most downsized homologated production ICE in the world, with 220hp per liter (using regular pump gas). The compact nature of the engine means the Regera is light in weight, and therefore nimble and efficient.
