In the 1920s and 1930s Andre Citroen put his marketing expertise to use by sponsoring two expeditions meant to show off the marriage of his body design with Kegresse's track system, as well as to demonstrate the ability of a half-track to cross extremely inhospitable land.

The first expedition (1922-1923) involved 12 people crossing the Sahara Desert from Toggourt, Algeria, to Timbuktu, Mali. It was the first exploration of that desert by motorcar.

The second, also known as La Croisiere Noire, traversed Africa from north to south, beginning on October 28th, 1924, and ending on June 26th, 1925.

The third, and most famous expedition, known both as the Citroen-Haardt Expedition and La Croisiere Jaune, commenced on April 4th, 1931 in Beirut, Lebanon, and followed Marco Polo's Silk Road route to Beijing, while seven other half-tracks left the Yellow Sea City of Tianjin to meet them part-way. The expedition was covered by publications such as National Geographic. The half-tracks survived Russian bureaucracy, arrest, bandits, rebels, severe weather, and the death of Georges-Marie Haardt, who succumbed to pneumonia at the end of the journey, but finally arrived in Beijing on December 2, 1932.
