The model's predecessor, the UAZ-450 (produced between 1958-1966), was based on the chassis and engine of the four-wheel drive light truck GAZ-69, and was the first "forward control" vehicle of this type to be built in the Soviet Union and Russia.^[1] The -450 was lightly revised and simplified, resulting in the -452.^[2] Because of the external similarities to a loaf of bread, the van became known as Буханка (bukhanka, loaf) in Russian. The ambulance version was nicknamed Таблетка (tabletka, a pill). The van is produced in several modifications, with the main difference being the body type (e.g. UAZ-3741 van (known as bukhanka), or the UAZ-3303 pickup truck, which is known as golovastik, tadpole).^{[citation needed]}
