In the 1914 Indianapolis 500, 2.5-liter and 4.5-liter engines were installed, while maintaining the same technical design. Results were not as bright as in 1913, due to technical problems (especially tires) rather than mechanical. Peugeot nevertheless took second and fourth place: Arthur Duray in the 3-liter class and Jules Goux in the 5.6-liter class.
