The Tatuus F4-T014 is a junior formula race car from Italian maker Tatuus, introduced in 2014. Its basic chassis is shared with the Tatuus MSV F4-016, Tatuus USF-17 and Tatuus PM-18. It was the first car homologated under FIA Formula 4 rules and debuted in the 2014 Italian F4 Championship, which Lance Stroll won. By 2015 the same chassis was used in the ADAC F4 and SMP F4 Championships. Other manufacturers like Mygale and Dome also entered FIA Formula 4 in different championships. In 2016 Tatuus expanded to supply the Spanish and UAE championships.

All Tatuus F4 cars use the Abarth 1.4-liter inline-4 engine. For BRDC Formula 4, the MSV used a different chassis, the RFR MSV F4-013. Tatuus adapted the F4-014 to a stronger Cosworth-Duratec engine. This car raced in the 2015 BRDC Formula 4 Autumn Trophy and was driven by Ben Barnicoat; the engine adds about 70 hp, making the car roughly 10 seconds per lap faster on many circuits, and it also has more aero adjustability.

Tatuus became the sole chassis supplier for USF2000 in October 2015, with the USF-17 replacing the older Van Diemen DP08. To handle oval racing, it includes zylon side intrusion panels and uses a 2.0 L Mazda engine. The USF2000 chassis also serves as the base for Pro Mazda, which uses the 2.0 L Mazda MZR-PM18A engine producing 275 hp. Mazda factory driver Joel Miller tested both the USF-17 and PM-18.

The Pro Mazda car and its USF2000 framework are designed to be used across all three USAC-sanctioned Road to Indy tiers: USF Juniors (JR-23), USF2000 (USF-22) and Pro 2000 (PRO-22).
