In 1971 Matra signed Chris Amon as team leader which frustrated Beltoise's ambitions. For 1972 he moved to the BRM team and won what turned out to be his only and BRM's final championship-qualifying Formula One victory at the 1972 Monaco Grand Prix in heavy rain. He spent three seasons with BRM, without much success and finally retired from Formula 1 at the end of the 1974 season.
