TheDallara SF23 is an open-wheel single-seater chassis produced byDallara for use in the JapaneseSuper Formula Championship. It debuted in2023, replacing theDallara 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 byHonda orToyota.[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]
A modified version built for autonomous racing designated EAV-24 is in use at theAbu Dhabi Autonomous Racing League. The EAV-24 had multiple modifications for self-driving racing, including a new sensor suite with cameras, RADAR, LIDAR and GPS, as well as a Honda K20C1 engine. A manned EAV-24 configuration exists.
