The Alda was a French automobile created by Fernand Charron of Charron, Girardot et Voigt (CGV). It was manufactured between 1912 and 1922. The car had a dashboard radiator and a 3,187 cc (194.5 cu in) inline-four engine that was claimed to be capable of going "6 to 47 mph in top gear" (9.7–76 km/h). Cars were available with the Henriod rotary valve system; another version featuring six cylinders was also offered. Post-World War I, the four was the only model offered, though it was rebored to 3,563 cc (217.4 cu in).
The name ALDA was invented by the readers of the magazine l'Auto, an acronym for "Ah - La Délicieuse Automobile!".
