The Japanese single-seater series has been working on an overhaul of the current Dallara SF19 package since the start of 2022, conducting a number of tests across a range of circuits with a pair of development cars.
Ahead of October's season finale at Suzuka, the final version of the 2023 car was demonstrated, featuring revised front and rear wings, sidepods, engine cover and floor, as well as new Yokohama tyres made partly from sustainable materials.
