There is little information about the Germain-Renault, it first appeared in August 1964 when it completed 2 laps of the Trophée de Cognac held at Cognac and then vanished until the same race the following year when it again failed to finish and was not seen again. Presumably the driver (and entrant) was also the constructor.

1964 Roland Germain.
