Overview
- The prototype’s hybrid system pairs a new 4.0‑liter twin‑turbo V8 with an electric motor integrated into the rear transaxle, aiming for at least 650 PS, around 850 Nm and a top speed above 320 km/h.
- An aluminum frame with carbon-fiber body panels underpins a targeted curb weight of up to 1,750 kg and a 45:55 front‑to‑rear balance achieved via the transaxle layout.
- Race-grade hardware includes carbon‑ceramic brakes from Brembo and Michelin Pilot Sport Cup 2 tires, with WEC team input enabling a functional aero package without a fixed rear wing.
- A newly developed eight‑speed automatic with a wet clutch and mechanical limited‑slip differential works with the e‑motor to mitigate turbo lag and sharpen throttle and shift response.
- Toyota also revealed the closely related GR GT3 race car, with both road and race programs still in development and series production of the GR GT targeted for 2027.
