Description
The Bonnet CBR 1 was a French sports car introduced in the early 1960s, designed and built by Charles Deutsch and René Bonnet, two prominent figures in French automotive engineering. This vehicle was developed under the brand name of Automobiles René Bonnet after Bonnet’s departure from his partnership with Deutsch in the firm DB (Deutsch-Bonnet). The CBR 1 marked one of Bonnet’s first independent efforts in creating a competitive racing car.
The CBR 1 was designed with aerodynamics in mind, a principle that Deutsch and Bonnet had previously applied to their race cars. The car had a sleek, low-slung body that was lightweight, largely constructed from fiberglass to reduce weight and improve performance. Its streamlined shape was intended to maximize speed and efficiency, especially in competitive motorsport environments.
Powering the Bonnet CBR 1 was a small engine sourced from Renault, which was a key supplier for Bonnet’s cars during this period. Typically, the CBR 1 was equipped with a four-cylinder engine, though various configurations existed, depending on the intended use. While not particularly powerful, the car’s lightweight construction allowed it to perform well on the track, particularly in endurance racing events.
The Bonnet CBR 1’s racing potential was one of its defining features, as it was designed to compete in various motorsport events, including prestigious endurance races like the 24 Hours of Le Mans. Its small engine size meant it often competed in lower-displacement classes, where its combination of light weight and agility gave it a competitive edge over heavier rivals.
Despite its promising design, the Bonnet CBR 1 was produced in limited numbers, as the company faced financial difficulties in the mid-1960s. These challenges ultimately led to Bonnet’s company being acquired by Matra, and the CBR 1 became one of the last cars produced under the René Bonnet name.
Today, the Bonnet CBR 1 is a rare and cherished example of early 1960s French racing engineering, appreciated for its innovative design and its role in the transitional period of French motorsport history. Its rarity and racing pedigree make it a sought-after car among collectors and enthusiasts of classic racing vehicles.
