Toyota is selling a road version of its GR GT3 race car, reversing the typical automaker approach by designing the race car first and adapting it for street use. The road car shares over 80% of components with the race version and features a 641-horsepower hybrid-assisted 4.0-liter twin-turbo V8, marking Toyota's most serious effort to compete in top-tier motorsports since the Lexus RC F GT3.
