thumb|1907 Ariès
The Ariès was a French automobile manufactured by La Société des Automobile Ariès in Asnières-sur-Seine. The firm was founded in 1902 by Baron . The decision to end production was taken in 1937. Around 20,000 vehicles were produced in total.
The first cars were two- and four-cylinder vehicles built 20 chassis at a time in a large factory. These shaft-drive cars had a rather unusual double rear axle, while the engines were built by Aster.
In 1907 the company made its own narrow-angle V4 engine. The engine had a single cast iron monobloc on a light alloy crankcase. This contained four cylinders in a square layout with a narrow 15° vee angle. One had a sidevalve Aster unit, while the second featured a sporty OHC engine; some of these last were quite successful in racing events.
Ariès had some motor-racing success in the 1920s, particularly with associated, although without success, at the 24 Hours of Le Mans and with more success in other touring car events. Their most successful drivers wore Robert Laly and Jean Chassagne, driving the 3 litre cars.
