About the car
Introduced during the 1979 season, the RT3 was Ralt's first ground-effect Formula 3 racer. Designed by Australian 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 gearbox, the RT3 could accommodate a choice of engines. Alfa Romeo, Toyota (as in this example), and Volkswagen four cylinder engines proved particular popular. Although very strong, the RT3 was also relatively heavy in it's 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 80's. Among the many successes were the British F3 Championship win for Ayrton Senna with this car and Pierluigi Martini's 1983 European Championship title with an Alfa Romeo powered example.
A change in regulations, effectively banning ground-effect aerodynamics, rendered the RT3 obsolete at the start of the 1985 season. It was replaced by the RT30, which was to some extent a flat-bottom evolution of the RT3. Between 1979 and 1984, Ralt built a total of 168 examples of what was one of the day's most successful Formula 3 racers.
More information about the development process carried out by Tauranac can be followed in the article linked below.
