The Dome F110 is an FIA Formula 4 standard formula car manufactured and marketed by Dome Corporation in collaboration with the Japan Motor Racing Industry Association (JMIA).[1] Since the 2015 season, it has been used as the sole car in the Japanese F4 Championship.
Until now, Formula 4 (F4) has been a regional category started voluntarily by local organizations and clubs, such as JAF-F4, but in 2014, the Fédération Internationale de l'Automobile (FIA) set guidelines for F4 standards and made it a global rule. At the time, JMIA President Minoru Hayashi was concerned about this and worried that Japanese-made entry-level racing cars would be eliminated and replaced by foreign-made cars from Western countries that had passed the FIA standards. Therefore, he tried to prevent this by developing a Japanese-made FIA-F4 as JMIA and partnering with the GT Association, but at the same time he was criticized by the organizations involved in JAF-F4.
The development process was done in collaboration with JMIA member companies, with the engine built by TOM'S and the gearbox by Toda Racing, while Toyota Motor Corporation provided support through Toyota Technocraft."[2]
In 2016, the ADR (Accident Data Recorder) and throttle failure safety were updated.
In 2017, the 6kJ tether and headrests and seats were updated in line with FIA rule changes.
In 2018, the FIA regulations were revised following an accident at a championship in another country (the vehicle was not company-owned), with the addition of front anti-intrusion panels and an updated rear structure. After the addition of this equipment, the minimum weight for the Japanese series was raised to 610 kg (1,340 pounds).
Due to revised FIA safety standards, conventional vehicles will no longer be allowed to be used after 2023, so the F110 will also cede its place to its successor, the MCS4-24 (built by Toray Carbon Magic), after that year.
As of 2015.[3]
In March 2019, it was announced that the F110 monocoque and key components would be used to supply the chassis for the EV race car."[4]
In January 2020, the concept of the ERA Electric Racing Academy Championship series was announced, with a one-make chassis called the 'Mitsu-Bachi' F110e, which is based on the F110 chassis. The series will be based on the F110 chassis and will feature a one-make chassis called the 'Mitsu-Bachi' F110e, with a total of four rounds planned in the second half of 2020 in the UK, Belgium and the Netherlands.[5]
