to tail slide. The hydraulic braking system also came from the Traction, though the drum brakes were the slightly larger ones from the 1911 cc Traction 11 version. The 1628 cc TUB went on sale on 5 June 1939, less than four weeks after its homologation. It was priced at 36,000 francs at a time when the base versions of the passenger cars from which it was derived were priced slightly above 26,000 francs. The TUB replaced by the TUC In September 1939 France declared war on Germany, and on 13 February 1940 a replacement version of the van appeared, described as the 11-T série U. The "11" in the van's name referred to its promotion to the 11CV taxation class which resulted from an increased engine size, now of 1,911 cc. Since the new vehicle was clearly an improved version of the Citroën TUB, respect for alphabetical logic ensured that it quickly became known as the Citroën TUC. The maximum load capacity was unchanged at but there were numerous detailed improvements including the fitting of a second windscreen wiper to match the one on the driver's side of the screen. This may have been the point at which a small protruding ridge appeared beneath the front panel, apparently as a half-hearted acknowledgement that most motor vehicles of this size featured a front bumper. Despite the German invasion in May/June 1940, the TUB continued in production until the Spring of 1941, and the TUC replaced it on the production lines only in May 1941. By now raw materials for civilian product and fuel for civilian transport were rapidly disappearing. Few TUC vans were produced, and production of them ceased in December 1941. About 100 models were transformed by Fenwick in 1941–1942 to be powered by an electric engine. Commercial Probably only about 1,740 of the vans were produced, most of them being the earlier 1628 cc TUB version which may appear a poor return for the effort that Citroën committed to the project. Nevertheless, when normal life began to return after the war Citroën were quick off the mark in 1946 with the Citroën H which was in many ways a slightly larger and less aggressively light-weight version of the TUB. The commercial success of the long-running H van owed much to its 1939 predecessor. References TUB Vehicles introduced in 1939
