Brissonneau et Lotz

In the 1950s Brissonneau and Lotz branched out into automobile production, building a small low volume cabriolet sports car based on the Renault 4CV, which was launched during the summer of 1956. A couple of years later, during 1958 and 1959 the small automobile factory was transformed into a substantial production facility when the company received a contract from Renault to assemble the manufacturer's stylish new Floride model. The Floride, later rebadged as the Renault Caravelle, would continue to be produced at the factory until 1968.

The company was also a contractor for Opel, making the body for the Opel GT sports car. Lower volume production of other car bodies continued until the factory closed in 1996 following an industrial dispute.
