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]
