The Alfa Romeo 308 or 8C-308 is a Grand Prix racing car made for the 3 litre class in 1938, only four cars was produced, actually modified from Tipo C with the engine mounted lower into the chassis and a slimmer body. The chassis was derived from the Tipo C and the engine from the 8C 2900. The 308 was engineered by Gioacchino Colombo under the control of Enzo Ferrari who was then in charge of Alfa's racing team, Alfa Corse. The car debuted at the Pau Grand Prix in 1938, two cars were entered to race, one for Tazio Nuvolari and the other for Luigi Villoresi. Both drivers had to withdraw from competition, however Nuvolari had by then set a lap record. The next race was the Tripoli Grand Prix. The new 312 (3-litre, 12 cylindres) and 316 (3- litre, 16 cylindres) were entered, but they got engine trouble during practice and Clemente Biondetti took the start at the wheel of the 308 held in reserve. He failed to finish while Hermann Lang driving a Mercedes-Benz W154 was the winner. In this race Eugenio Siena driving a 312 was killed after hitting a wall.
