The Dallara SF23 is an open-wheel single-seater chassis produced by Dallara for use in the Japanese Super Formula Championship. It debuted in 2023, replacing the Dallara SF19 chassis as the main chassis used in Super Formula. [1]
The single-seater SF23 was presented on 13 December 2022. [2] The car was developed through seven test sessions, covering 10,000 km (6,200 mi). [3]
Compared to its predecessor, the SF23 has important aerodynamic differences in order to guarantee a greater possibility of overtaking. The ailerons, bellies and bottom are modified. [3] Like the SF19, it is equipped with engines supplied by Honda or Toyota. [1]
For some components of the bodywork, materials derived from flax fiber, cork and recycled carbon fiber are used. [2] This allows for a 75% reduction in carbon dioxide emissions in the production process. [3]
