Euro 4 Championship, known since 2025 as the E4 Championship, is a formula racing series regulated according to FIA Formula 4 regulations. The championship was inaugurated in 2023 and was designed to provide more racing opportunities for teams and drivers in Italian F4 Championship after the folding of ADAC Formula 4.[1]
History
The series is run by ACI and promoted by ACI Sport and WSK Promotions, the latter is well known for running prominent karting championships including the WSK Euro Series.[2] The series was confirmed when the calendar for the inaugural season was announced in April 2023, with three rounds supporting the Formula Regional European Championship.[1]
The series faced minor challenges in its first year, after results for the second race in Monza were frozen for a month due to confusion over one marshal post showing a safety car board when no safety car had officially been called.[3] Nonetheless, the series showed close racing and a title fight with only a two-point gap going into the final race, where Ugo Ugochukwu was declared the inaugural champion.[4]
The 2024 season saw Akshay Bohra, who won two races in the opening round, take victory after title rival Freddie Slater was affected by post-race penalties and damage in the final weekend.[5]
Euro 4 was renamed to E4 prior to the 2025 season.[6]
Cars
The series uses the Tatuus F4-T421, the same car as Italian F4.[2] It is built by Italian race car constructor Tatuus.[7] The engine is a 1.4L turbocharged Abarth engine,[8] and the tyres are provided by Pirelli.[1]
