The 25CV was a car produced by the luxury French automaker De Dion-Bouton.

After the First World War, De Dion-Bouton did not realise that there was a need for popular models to be inexpensive and economic, so initially the company went to market with prestige models. The 25HP was one of the last cars produced by the manufacturer to be mounted a V8, which in this case had a displacement of 3695cc. The engine was mated with a 4-speed transmission and power was sent to the rear wheels. The suspension setup was semi-elliptic leaf springs all round.

After the commercial failure of this car, De Dion-Bouton went on a production break in order to let the company recover before starting the production of more affordable cars.
