Toyota Gazoo Racing stated that the GR GT3 consists of more than 80% components shared with the road-going GR GT. For comparison, the previous Lexus RC F GT3 had about 25% commonality.
The reason lies in the very concept of the project. Toyota developed the GR GT as a “racing car first and foremost,” and adapted the road model to the requirements of everyday use. Therefore, the cars share an aluminum space frame, suspension, and a significant part of the body solutions.
Both versions received a new 4.0-liter twin-turbo V8. The road-going GR GT uses a hybrid system and develops 640 hp and 850 N·m, while the GR GT3 lacks an electric motor due to FIA GT3 requirements.
At the same time, the racing version differs significantly in aerodynamics: it received enlarged air intakes, developed fenders, and a large rear wing. Toyota plans to bring the GR GT and GR GT3 to race tracks starting around 2027.
This approach is interesting not only to motorsport fans. The more common components between racing and road cars, the closer the production car is to the technical basis of a real GT3-bolide.
