Soissons, 75 miles north-east of Paris, is not noted as an industrial centre, but the 1900 Guide Michelin includes under the town's details: "Deliry père et fils, constructeurs d'Automobiles". Colliot was the name Deliry père called the cars he made with his son and these voiturettes were noted for having a 4hp air-cooled V-twin engine, placed at the front. This drove through a conventional gearbox, with side-chain drive. A water-cooled model of the same layout was also offered, powered by a 4½hp De Dion-Bouton engine.
The unique surviving Colliot was for many years known as a 'De Dion-engined car', its correct identity not being established until 1997.
