The base chassis for the series is the Dallara SF19, which was unveiled at Suzuka Circuit in October 2017. The SF19 was regulated to weigh 670 kilograms (including driver), and is powered by two-litre single turbo-charged engines from Honda and Toyota. While sharing the same base architecture as the NRE engines used in Super GT GT500 cars, the engines are detuned relative to their GT counterparts. It features a 'push to pass' style overtake system which allows for additional 5 kg/h of fuel flow to be used when active - increasing power.

The previous generation of the car, the Dallara SF14, was used between the 2014 to 2018 season, which featured at least 30% components manufactured in Japan.[1]

Comparable to a contemporary Formula One, the pole position lap in a Super-Formula Dallara SF14 at Suzuka Circuit in 2017, 1:35.907, is 8.588 seconds or 9.0% slower than the pole position time for the 2017 Japanese Formula One Grand Prix.
