Then in 1933, it became the property of the car manufacturer, Citroën, who installed a testing facility for the brand’s own cars.
As needs evolved, new facilities were added, including the timing tower, grandstand and pit.
In 1946, UTAC, an industrial test laboratory, took over the tracks’ management, eventually gaining ownership much later, in 1973.
In the 2000s, UTAC undertook major renovation work to bring the track up to regulatory standards, To the delight of motor enthusiasts, the speed circuit was finally accredited again in 2010.
