Improvements
- Leveraging lessons learned from competing in Japan's Super Taikyu Series, the car's fundamental performance has been enhanced so that it can be put to the test in evermore demanding settings.
- The body structure has been reinforced to endure vertical and lateral g-forces that are more intense than those typically generated at circuits in Japan.
- To maintain stable engine output even during prolonged full-throttle driving, a cool air duct has been added to reduce the intake-air temperature during high-load driving.
- The JBL Premium Sound System (factory-installed option) has been improved by equipping the car with an Active Sound Control system and installing a subwoofer in the luggage compartment to enhance comfort for greater enjoyment of everyday driving and create burgling and other sounds that evoke the feeling of motorsports.
- The supply system for the Japanese-market model has been revised to enable delivery to as many customers as possible.
