Eurocup-3 is a formula racing series regulated according to Formula Regional regulations. The series is founded for levelling up the competition for all drivers, with each team committing on a maximum budget of €400,000 every season.
Teams use the identical Tatuus F3 T-318 chassis from the Formula Regional European Championship, but these chassis are provided with a new intercooler, updated body kit, and battery kit. This updated car is called as the Tatuus F3 T-318-EC3, and it weighs 25 kg (55 lb) less than the Tatuus F3 T-318. The car is fitted with a 270 hp (200 kW) Alfa Romeo-Autotecnica engine and Hankook tires. There is also a push-to-pass system used in these cars which provides an additional 25 hp (19 kW).
