Deutsch-Bonnet was a partnership between Charles Deutsch and Rene Bonnet that began in 1938 to build race cars. D-B cars were very successful on the racing circuit and dominated the world’s race tracks through the 1950s and early 1960s. In 1961 the partners split. Deutsch wanted to continue using Panhard running gear on their race cars but Bonnet wanted to change to Renault. While Deutsch went on to provide independent engineering consulting, Bonnet continued to make cars under his own name and also became a driver for Renault. The CBR/1 is the only example. It is believed to have been Rene Bonnet’s personal car.
