The high performance Berlinetta 8C 2900B is powered by a 2.9-liter 8C engine derived from the grand prix single-seat Tipo B from 1934. It has twin superchargers and suspension and brakes based on Alfa racing cars from 1935 to 1937. These were some of the fastest road-going car of its time. The Superleggera body by Touring of Milan is built in lightweight alloy over a latticework of small-diameter steel tubes assembled over the chassis. An 8C 2900B Lungo bodied by Touring won the 1947 Mille Miglia, driven by Romano and Biondetti, the last of the eleven wins at the Mille Miglia by Alfa Romeo.
