Dallara SF19
The Dallara SF19 is an open-wheel single-seater chassis produced by Dallara for use in the Japanese Super Formula championship. It debuted in 2019, replacing the Dallara SF14 chassis. Throughout its production, it was the sole chassis used in Super Formula, however an engine development war between Honda and Toyota can lead to significant performance differences between the Honda and Toyota powered models.
