In 1911, Adolphe Kegresse, head of the garage of the Russian Czar in St Petersburg, modified the Czar’s Rolls Royce with tracks in order to go hunting on the snow. 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.
