マーチ・エンジニアリング
Jarier was born at Charenton-le-Pont, near Paris. After competing in Formula France, he moved up to French Formula Three, finishing 3rd overall in 1970, before moving on to the Shell Arnold European Formula Two team in 1971. He peaked with two 3rd places, and also made his Grand Prix debut at Monza when the team rented a March Engineering 701. However, the team dropped him midway through 1972 for financial reasons. For 1973 he signed to the March Engineering Formula Two team, and was also given a Formula One seat by the outfit. Formula One was difficult in the uncompetitive 721G, but Jarier stormed to the Formula Two title with eight wins.
