Start with what the Renault GS is: a 4-door Torpedo / 4-door sedan / 2-door truck / 2-door bus with I4 2120cc, 10CV, 15HP, built from 1919 to 1920, as the assembly line was turning motoring into an industry. What it meant takes a little longer. The shape is credited to Louis Renault.
The engineering
The engine is I4 2120cc, 10CV, 15HP. On the scales it comes to 600 kg. Drive goes through a 3-speed manual. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is 2620 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
In the Renault line-up the Renault GS has a clear place: it replaced the Renault FK; it handed the line to the Renault IC, Renault IG; the factory was Île Seguin, Boulogne-Billancourt, Paris. The cars a buyer would have weighed it against include the Citroën Citroën, the Hispano-Suiza H6, the Fiat 505. Its Renault stablemates include the Renault 10 and the Renault 10CV.
Owning one today
There is no federal ownership record for the Renault GS — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
