Autobleu began in business by supplying components for improving the appearance of the Renault 4CV, moving on to complete rebodying of the 4CV. Spring 1953 saw a 2-door coupe with wrap-around rear window styled by Ghia. These sold in small numbers, but were hampered by their price, more than double that of a regular 4CV saloon. Unlike Alpine, Autobleu did not modify the Renault's engine to improve performance. A convertible styled and built by Chapron was announced in 1955, when Autobleu made a single example of a coupe based on the larger, front-engined Renault Fregate. The body was styled and built by Boano.
