Charles Deutche and Rene Bonnet began racing specials in 1939 and quickly proved to be amongst the best builders in France with Panhard based GT and sports cars.

Their 500 was based around a modified Dyna Panhard flat twin engine which was mounted ahead of the front driven wheels. The engine's 10:1 compression developed 35 HP at 7,000 rpm. The chassis was box section with Panhard dual transverse springs for the front suspension and, at the rear, a pair of telescopic dampers acting on a solid axle. One of the faster drivers was Elie Bayol who went on to race in Formula 2 and 1 with OSCA and Gordini.

The DB was hampered by a relative lack of power compared with the JAP and Norton engines favoured by the English however, in the right hands and on the right circuit, it could be competitive. Deutche Bonnet were able to set a number of records at Montlhery in October 1950 but these were short lived, while awaiting ratification, the Kieft team raised the bar only a month later.
