Citroen Traction Avant is a French passenger car from the interwar period, World War II and the post-war period. The first copies of this car appeared in 1934, and serial production continued intermittently in the years 1934-1957. Approximately 760,000 cars of this type were produced in its course. Citroen Traction Avant - depending on the version - was powered by a single engine with a capacity of 1.3 to 2.9 liters. The Citroen Traction Avant was presented for the first time at the Paris Motor Show in 1934. At that time, it was characterized by many innovative technical solutions: front-wheel drive, independent wheel suspension, hydraulic brakes on all wheels or a self-supporting body. It also had - for those times - an innovative exterior design. The car was characterized by great road characteristics and very good road holding, even when cornering. Due to the engine used, three main versions of the Citroen Traction Avant appeared: 7CV (1.3-liter engine), 11CV (1.9-liter engine) and 15CV (2.9-liter engine). At the outbreak of World War II, many of these cars were mobilized and served as staff cars for officers - first French and after 1940 - German armed forces throughout World War II.Renault AHx is the collective name of a family of French, mainly military, WWII and post-war trucks. The first prototype vehicles of this family appeared in 1940, and serial production continued in 1941-1947, mainly in the Boulougne-Billancourt plant in the suburbs of Paris. In the AHS version, the car was powered by a single gasoline engine with a capacity of 2.4 liters and 52 HP, while in the AHN and AHR versions the engine had a capacity of 4.05 liters and an output of 75 HP. In 1939, in France, and more precisely at Renault, work began on a new series of 2-axle trucks with a load capacity of 2.5 tons (AHS model), 3.5 tons (AHN model) and 5 tons (AHR model). When designing all three trucks, care was taken to keep as many common mechanical components as possible and to keep production costs as low as possible. All models also used the same driver's cab, with a sloping front being a special feature. The first prototypes appeared in 1940, but due to the defeat of France in the same year, serial production started in 1941 for the needs of the German occupier. The main model, produced on a fairly large scale (about 4,000 copies), was the AHN version, serving in the German armed forces under the designation LKW 3.5t AHN. It was very often used as a transport car or light artillery tractor.
