In 1979, Claude and Bernard Marreau caused a stir at the Paris-Dakar rally by placing their modest little Renault 4 just behind the leaders. Three years later, the two brothers had another go with a car they had designed themselves: a four-wheel drive Renault 20 prototype fitted with a turbo engine. Their navigation and driving skills, coupled with the qualities of the car, saw them beat the big favourites in the Ladas and Mercedes. Having beaten almost 400 competitors, the Marreau brothers became known as the "desert foxes" and returned to compete in the race again in a Renault 18 V6. Their success would be echoed by the two wins of the Schlesser-Renault buggy at the turn of the century.
