マーチ・エンジニアリング
In 1970, Williams undertook a brief partnership with Alejandro de Tomaso. After the death of Courage at the Dutch Grand Prix that year, Williams's relationship with de Tomaso ended. In 1971, he raced Henri Pescarolo with a chassis purchased from March Engineering; 1972 saw the first F1 car built by the Williams works, the Politoys FX3 designed by Len Bailey. Pescarolo crashed and destroyed it at its first race.
