"A sports car built in the experimental workshop of the Minsk Automobile Plant in 1956 by A. Krasovsky and V. Mayboroda. The design was based on a tubular spatial frame, the suspension of all wheels was torsion (the front was independent, the rear was of the De-Dion type), and the engine was Moskvich-402. The car was built in a short time, almost without blueprints, for the 1956 USSR Championship. Since Minsk was announced late for the competition, it was not submitted to the technical commission and was therefore allowed to participate outside the competition. Krasovsky and Mayboroda on this car went the entire distance and actually took tenth place. “Minsk” did not participate in other competitions."
