Léon Dufour was appointed chief designer and later added technical director to his job titles.
Pictet travelled to Barcelona in early 1905, and while there met with fellow Swiss Marc Birkigt of Hispano-Suiza.
During World War I, the Swiss Army ordered a large number of Pic-Pics, which were known for their robustness.
Henceforth, Gnome et Rhône produced Pic-Pic cars, the last one being presented at the 1924 International Geneva Motor Show.
The Pic-Pic's ability to travel up to 128 kilometres per hour simulated the velocity of the aircraft at the time.
Two Pic-Pics with 4.5-litre engines and front-wheel brakes competed in the 1914 Grand Prix, but both cars were withdrawn.
