The Alva Sport was a French automobile manufactured from 1913 to 1921 or 1923 by a company named Automobiles Alva in Courbevoie, Seine. The car used two different four-cylinder engines, either an ohv 1496cc unit or an ohv 2651cc unit. Even though the vehicles were fitted with Perrot front-wheel brakes , Alvas suffered from archaic parts such as a cone clutch .
