He went up against several high-profile racers in this weekend's event in Karlsoga, around 235km west of the capital, Stockholm.
Among them was ex-Formula 1 world champion Jacques Villeneuve, who placed 11th in the official test - just five places above the prince.
Villeneuve placed 16th out of 17 in the first race of the day - one that the prince didn't manage to finish.
