A new lightweight riveted alloy body was designed and also built by Piero Drogo. It was an more boldly designed machine, oriented to endurance contests. It uses normal ISO underpinnings but the engine was moved further last the chassis frame as opposed to Grifo A3L, protruding well into your driver's cabin, fitted with hot cams and fed by some big Weber carburettors, giving more than 500 bhp (298 kW; 406 PS).

All-around 29 A3C sport cars were built beneath ISO name. Five of these 28 cars were bodied throughout plastic/fiberglass by Piero Drogo on Carrozzeria Sports Cars within Modena.
