The Toyota H8909 engine family is a series of twin-turbocharged, four-stroke, 2.4-liter and 3.5-liter, V6 racing engines, made by Toyota Gazoo Racing for use in their TS050 and GR010 Hybrid Le Mans Prototype race cars, since 2016.

TS050 engine

The TS050 Hybrid uses a 2.4-liter twin-turbocharged petrol V6, and features an 8-megajoule hybrid system, which uses lithium-ion batteries.[1] The capacitor hybrid energy storage system was replaced with a new lithium-ion battery system, with the car now moving to the 8-megajoule LMP1 Hybrid sub-class.[2] The ICE makes 368 kW (493 hp; 500 PS), and is complemented by electric motors, giving an additional 368 kW (493 hp; 500 PS).[3][4]

GR010 engine

The GR010 Hybrid's engine is an enlarged 3.5-liter twin-turbocharged petrol V6, with a hybrid system, which also uses lithium-ion batteries.[5] The ICE now makes 500 kW (671 hp), plus another 200 kW (268 hp) from the electric motors.[6]
