Dallara SF23

The Dallara SF23 is an open-wheel single-seater chassis produced by Dallara for the Japanese Super Formula Championship. It debuted in 2023 as the replacement for the SF19 and was presented on 13 December 2022, after development through seven test sessions covering 10,000 kilometres. Compared with its predecessor it has aerodynamic changes to the ailerons, bellies and floor intended to give a greater possibility of overtaking, and like the SF19 it uses engines supplied by Honda or Toyota. Parts of its bodywork use flax fibre, cork and recycled carbon fibre, which allows a 75 percent reduction in carbon dioxide emissions in the production process. A modified version, the EAV-24, is used for autonomous racing in Abu Dhabi.
