EFO - EuroFormula Open Championship

The EuroFormula Open Championship (EFO) is an international single-seater racing series that serves as a direct feeder category to Formula 3 and, ultimately, Formula 1. The championship mandates the use of the Dallara 320 chassis, powered by the current-specification Mercedes-AMG 2.0-liter turbocharged engine, adhering strictly to FIA Formula 3 technical specifications to ensure a high standard of competition. The series is highly respected for its open regulations, which allow teams to choose their engine supplier within specified parameters, fostering technical development alongside driver skill. EuroFormula Open races take place on established European Grand Prix circuits, frequently sharing race weekends with the FIA Formula 1 World Championship or the Formula 2 Championship, which provides maximum exposure for its young drivers. The championship emphasizes a blend of talent identification and competitive racing, making it a vital proving ground for aspiring single-seater stars aiming for the pinnacle of motorsport.
