In the 1920s and 1930s, Andre Citroen put his marketing expertise to use by sponsoring two expeditions meant to show off the combination of his vehicle design married to Kegresse's track system, and demonstrate the ability to traverse extremely inhospitable land.

The First expedition, in 1922 and 1923, involved 12 people crossing the Sahara Desert, and represented the first exploration of that desert by motorcar. The second, known as La Croisiere Noire, traversed Africa from North to South, beginning on Oct. 28th, 1924, and ending on Jun. 26th, 1925.

The third and most famous expedition, known as the Citroen-Haardt Expedition and La Croisiere Jaune, went from Beirut, Lebanon and followed Marco Polo's Sil Road route all the way to Beijing, while seven halftracks left the Yellow Sea city of Tianjin to meet them part-way. The expedition was covered by National Geographic magazine, and survived Russian bureaucracy, arrest, bandits, rebels, severe weather, and the death of Geroges-Marie Hardt who passed away at the end of the journey after arriving at the final destination of Beijing on Dec. 2nd, 1932.
