1975 began Jarier putting his Shadow DN5 on pole position for the Argentine Grand Prix, only for a component to break in the warm-up, preventing Jarier from taking the start. He repeated the feat at the Brazilian Grand Prix, and then dominated the race until a fuel metering unit failed, ending his race. Bad luck and poor reliability would curse his season, though the Shadow team fell from the pace as well. His only points-scoring finish was for 4th place in the shortened Spanish Grand Prix.
