Super Formula, Japan’s top-line single-seater series, has completed the development of its new spec chassis and confirmed it will be introduced in 2023.
Unveiled in October 2021, the joint development project between the series and its two engine suppliers, Honda and Toyota, utilizes a number of technologies that are new to high-end motorsport.
Dubbed the SF23, the updated Dallara chassis uses a new bodywork by Swiss company Bcomp, which is made from a bio-composite material that “maintains the same strength and weight as conventional carbon materials, but focuses entirely on the use of natural materials.” According to the series, hemp-derived materials.
By switching from carbon fiber to bio-composite, the reduction in carbon dioxide emissions from manufacturing alone is said to be 75 percent. Following breakdowns when parts need to be replaced, this would be a more sustainable method of supplying spare parts.
The bodywork is also being revised for 2023 to change the cars aerodynamic profile. This is being done with a close racing focus and includes radical changes to the front and rear wings and additional aerodynamic accessories on the side pods.
Tire supplier Yokohama has worked to create a more sustainable product. It says its single-profile sliding composites will be made from “approximately 33% recycled and renewable raw materials” by 2023. Yokohama claims it is the first “carbon neutral racing tyre”, following Super Formula’s ambition to become a carbon neutral series, a target shared by F1.
More than 10,000 kilometers of testing were completed on several circuits in Japan with new bodywork and tires.
Technical improvements to the series include the introduction of F1 TV-style live streaming and archive video services, such as team radio listening and live telemetry viewing, with an improved digital media approach.
The full grid for the Super Formula 2023 season has already been announced, with three rookies making it to the series. Red Bull junior Liam Lawson has left Formula 2 to race for Team Mugen, Formula Americas champion Raul Hyman has landed a seat at B-MAX Racing on scholarship from Honda, and Super Formula Lites racer Kakunoshin Ota has been offered a seat. Chance on Dandelion Racing.
