Subaru will be heading to Le Mans next season, but not in the way fans of the automaker would like to see.

Instead of campaigning a race car, the Japanese automaker will be an engine provider with its new FA20DIT powerplant. The engine is being developed as a highly-efficient racing engine for Le Mans Prototypes and is a 1.6-liter turbocharged Boxer engine based on the standard Subaru block.

The powerplant is expected to produce around 550 hp and will be able to operate with very little cooling thanks to its use of a patented “Pseudo Adiabatic” combustion process. Though the engine is a bit on the heavier side, weighing in at around 285 lbs, teams using it will benefit from a highly fuel-efficient engine and can enhance their race car’s aerodynamics as a result of the reduced cooling demands.
