 Peugeot's engine design had a lasting influence U.S. engineers for many years.Cars from previous campaigns remained in the United States, and were sold to American drivers, among them Harry Arminius Miller who would soon copy this exceptional mechanical architecture to overcome its cleaner engines in 4 and 8 cylinder versions, then after the bankruptcy of Miller, Fred Offenhauser who was one of Miller's employees in the 1930s.This type of engine in 4 cylinders form was used until the end of the 1970s, with the final win at Indy by Offenhauser in 1976.
