The 2018 Japanese Super Formula Championship was the forty-sixth season of premier Japanese open-wheel motor racing, and the sixth under the moniker of Super Formula.
The season began on 22 April and is scheduled to end on 28 October at the same place after seven rounds.
[1] 2018 was the final season that the Dallara SF14 chassis package—which débuted in the 2014 Super Formula Championship—was used in competition; as a brand new chassis package will be introduced for the 2019 season but the engine configuration will remain the same.
Every Honda-powered car used a Honda HR-414E engine and every Toyota-powered car used a Toyota RI4A engine.
Due to scheduling restrictions imposed by the concurrent Japan WTCR round, the final round of the calendar at Suzuka Circuit will now feature a single race instead of the originally planned double-header.
