NSX-GT

The NSX-GT cars are designed to comply with Class 1 regulations.

Regulations mandate the use of up to two 2-litre 4-cylinder directly injected turbo (NRE) engines per season. The engines must meet fuel flow restrictions, requiring durability, reliability and high efficiency. Honda teams are powered by the HR420E engine.

In the GT class, each racing car is generally shared by two drivers, racing a distance of 300 - 500km (2021 season) per race. Car performance is evened through Success Weights and fuel flow restrictions according to championship points, leading to new winners and heated battles in nearly every race.

SUPER GT, successor to the All Japan Grand Touring Car Championship which began in 1994, is the premier Japanese semi-endurance racing category. The series has been gaining popularity, with world-class drivers racing in the category, such as former F1 champion Jenson Button.
