Introduced during the 1979 season, the RT3 was Ralt's first ground-effect Formula 3 racer. Designed by Ron Tauranac, it replaced the highly successful RT1 but was relatively late to arrive as rivals Chevron, March and Martini had their ground-effect racers ready before the start of the year. So very few teams switched to the RT3 and only four examples were built in 1979. However, it would not take long before the ground-effect Ralt carried on where the RT1 had left off.
To cope with the substantially increased loads created by the ground-effect aerodynamics, Tauranac ensured the RT3 aluminium monocoque chassis was up to the task by reinforcing the bulkheads with aluminium honeycomb. The chassis itself was very narrow and the suspension was mounted inboard, creating room for very wide side-pods, which, thanks to their wing-shaped floors, generated the ground-effect aerodynamics. Mainly for balance reasons, the very elegant RT3 also featured a front and rear wing.
Equipped with a Hewland MK9 gearbox, the RT3 could accommodate a choice of engines. Alfa Romeo, Toyota and Volkswagen four cylinder engines proved particularly popular. Although very strong, the RT3 was also relatively heavy in its original guise, which also accounted for the lack of success in 1979. Tauranac addressed these issues and due to continuous development the RT3 remained very competitive well into the mid 1980s. Among the many successes were the British F3 Championship win for Ayrton Senna with a Toyota engined car and Pierluigi Martini's European Championship title with an Alfa Romeo powered RT3, both in 1983.
This car, prepared at the time by Seresina, debuts in the Italian F3 championship of 1984 with Alex Caffi for Euroteam placing second at the end of the season just 6 points behind the winner. That year Caffi also dispute the Gran Premio Lotteria di Monza and the 28th Grand Prix F3 Montecarlo, where, however, was forced to retire.
In the year after the car passed in Formula 2000 and kept running, with Euoteam up to 86 and up to 88 Prodan. Besides Alessandro Caffi on this car they took turns shouting numerous drivers, including Ivan Capelli and Alessandro Barlassina.
