Automobiles Christiane Huit was a French automobile manufacturer based in Rennes, Ille-et-Vilaine, operational from 1927 to 1929. The company was founded by A. Andrieux, who designed and built the vehicles under the brand name that reflected the car's eight-cylinder configuration.

The initial model featured a chassis that utilized a Citroën B2 engine, which was modified to an overhead valve system. This was later replaced by a 1980cc single overhead cam (SOHC) straight-eight engine, also developed by Andrieux. The car was equipped with twin Cozette carburetors and achieved a top speed of approximately 90-93 mph (145-150 km/h). It was designed with a four-seat sports body, notable for its staggered rear seats.

Andrieux actively participated in various local hill climbs and sprints, achieving commendable results, including a notable performance in the 1927 Targa Florio, which took place in Brittany that year. Following this, he developed a lighter, shorter model that was strictly a two-seater and featured disc brakes. Although Andrieux planned to produce cars with similar engines in 2, 2.5, and 3-litre sizes, the onset of the Great Depression led to the postponement of these plans, and the company ultimately ceased operations without reviving its production.
