Japanese Consortium Advances Super Formula Next-Generation Car Development
A group of Japanese manufacturers, led by the racing car constructor Dome, has put forward a proposal to build the upcoming Super Formula vehicle. This collective, known as the Japan Motor Racing Industry Association (JMIA), which includes 80 companies, has developed a prototype, the JNFP-1, with aspirations of it replacing the current Dallara SF23 chassis.
The JNFP-1 adheres to contemporary Formula 1 safety regulations and is engineered to accommodate the existing two-liter, four-cylinder turbo engines provided by Honda and Toyota. It distinguishes itself from the SF23 by featuring low-profile 18-inch wheels and, despite having comparable dimensions, weighs 750kg with the driver, making it 73kg heavier than the current model. Dallara has been the exclusive chassis provider for Super Formula since 2014, succeeding American constructor Swift, and has produced two distinct chassis, the SF14 and SF19, with the SF23 being an aerodynamic enhancement to the SF19 introduced three years ago.
Following an unsuccessful attempt to enter Formula 1 almost two decades ago, Dome resumed single-seater production in 2015, developing the F110 for Japan's domestic F4 series and, more recently, the F111/3 car under Formula Regional specifications. While Dome was the principal designer, numerous other firms, including Toyota's TGR-D, Team Mugen's parent company M-TEC, Toda Racing, and Toray Carbon Magic, which manufactures the current GT500 chassis for Super GT, contributed to various aspects of the project. The JNFP-1 was first showcased publicly in Yokohama in May and later at the fourth round of the season in Fuji. Simulator trials with former Super Formula driver Kazuya Oshima have commenced, and an on-track debut is anticipated in the coming months.
JRP president Yoshihisa Ueno expressed admiration for the JNFP-1 at Fuji, though he emphasized that its adoption by the series is "nothing decided." He further noted that the machine's value extends beyond its potential adoption, highlighting the collaboration of over 40 Japanese constructors in building the prototype as a significant step toward elevating Japan's motorsport sector. Ueno clarified that selecting the next-generation car is a complex process, requiring a grid of 30 cars, assured safety, reliable supply, and manageable costs, and is not solely determined by the promoter. The ultimate decision will hinge on whether teams genuinely wish to compete with the car and if fans are enthusiastic about watching races featuring it. Last year, Ueno indicated to Autosport that the current Dallara SF23's lifespan might be prolonged beyond 2027 as options for its successor are deliberated. The earliest the JNFP-1 could be produced in sufficient numbers to supply the entire grid is estimated to be 2029 or 2030.
This endeavor underscores the power of collaborative innovation and national pride in pushing technological boundaries within competitive sports. By fostering a collective spirit among diverse companies, the project not only aims to revolutionize Super Formula but also to uplift the entire Japanese motorsport industry, inspiring future generations to pursue excellence and innovation in engineering and racing.
