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. The H8909 engine is currently developed at Toyota Gazoo Racing's engine plant in Susono, Japan and assembled and prepared at Toyota Gazoo Racing's European division in Cologne, Germany and initially designed by former Toyota Gazoo Racing LMP1 powertrain director Hisatake Murata.
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 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]
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 makes 500 kW (671 hp), plus another 200 kW (268 hp) from the electric motors. [6]

The Porsche 919 Hybrid is a Le Mans Prototype 1 (LMP1) dual hybrid racing car built and used by Porsche in the 2014, 2015, 2016 and 2017 seasons of the FIA World Endurance Championship. It has a two-litre (120 cu in) 90-degree V4 mid-mounted mono-turbocharged petrol engine that produces 500 hp (370 kW) and acts as a chassis load-bearing member – and two separate energy-recovery hybrid systems to recover thermal energy from exhaust gases and convert kinetic energy into electrical energy under braking for storage into lithium-ion battery packs. In accordance with the 2014 regulations, the vehicle was placed in the 6 MJ (1.7 kWh) class.
The Toyota TS040 Hybrid is a Le Mans Prototype 1 (LMP1) sports car built and used by Toyota Motorsport GmbH in the 2014 and 2015 seasons of the FIA World Endurance Championship. Work on the car's design began in November 2012, when the Automobile Club de l'Ouest (ACO) published its 2014 technical regulations and Toyota utilised its resources after the 2013 24 Hours of Le Mans. The car is an aerodynamic improvement on its predecessor, the TS030 Hybrid, and its design allowed four-wheel drive. It has two kinetic energy recovery system (KERS) regenerative-braking devices at the front and rear axles to charge a supercapacitor and, in accordance with the 2014 regulations, was placed in the 6 MJ (1.7 kWh) class. The TS040's engine was carried over from the TS030; its displacement was increased from 3.4 L (210 cu in) to 3.7 L (230 cu in) for better efficiency, producing 513 horsepower (383 kW) to the rear wheels.
