The Moskvich 400 is a pioneering Soviet compact car produced from the mid-1940s to the mid-1950s. Based on the pre-war Opel Kadett, it marked one of the first mass-produced Soviet vehicles, focusing on simplicity and affordability. Across its generation, the Moskvich 400 maintained its compact dimensions, featuring modest size and weight suitable for urban use. The car's legacy is significant in Eastern European automotive history, representing industrial recovery and growth post-World War II.
