Thecar was built starting from the Alfa Romeo 8C 2900 B chassis No. 412.033, on which the engine No. 422022 was mounted. The bodywork designed by Touring uses a “thick wing” profile in the lower part and a “Kamm type” trunk fairing to cover the riders’ heads. The lightweight aluminum panels that form the body are applied to a8C2900A had a 2905cc engine with a 6.5:1 compression ratio, producing 220bhp @ 5300rpm. 2900B, used a detuned derivative for more reliability with the same displacement, bore/stroke of 68/100mm, and DOHC 2Valves/Cyl valve gear, but a different compression ratio of 5.75:1. It was boosted, like 2900A, with a Twin Roots Supercharger
The8C 2900B was built because Alfa Romeo wanted to continue dominating Italy's Mille Miglia race. It also needed a production car to replace the 8C 2300. The 2900 chassis with its supercharged 2905 cc, 180 bhp engine proved to satisfy both needs. Three cars were entered in the 1936 Mille Miglia and finished in order.
