Toyota develops new V8 hybrid engine for GR GT supercar

Toyota is advancing development of its upcoming GR GT supercar, which is expected to enter production in 2027. The vehicle will feature a new 4.0-liter twin-turbo V8 hybrid engine designed to meet GT3 racing regulations.

The engine architecture places turbochargers between the cylinder banks to reduce exhaust gas travel distance and lower the engine's center of gravity. To manage extreme temperatures, Toyota has implemented thermal protection technology typically used in aviation. The hybrid system includes a small electric motor positioned between the engine block and the eight-speed automatic transmission.

Initial performance targets for the powertrain are approximately 640 to 650 horsepower and 850 Nm of torque, though Toyota suggests these figures may increase. The GR GT will utilize a rear-wheel-drive layout with a rear-mounted engine and a weight distribution of 45:55. To manage weight, the car will feature an all-aluminum chassis and a body constructed from aluminum and carbon fiber, with a target weight of approximately 1,660 kilograms.
