RALT Ayrton Senna`s RT3 Formula 3 Editorial Photo

RT3 has a long history - a 1979 ground effect Formula Three car which was enhanced every year until 1984, becoming the dominant car in the formula. Ayrton Senna won the 1983 British Formula Three Championship driving an RT3. RT30 was introduced for the flat-bottom rules coming into effect in 1985. This was notable mainly for being very asymmetric - it had only one sidepod containing a radiator, and a deformable structure panel on the other side. The RT30 was, like many Ralts, developed over several seasons, evolving by the 1985-6 seasons into a highly competitive car, although some teams converted their old RT30s into flat-bottom cars and enjoyed a measure of success with these.
