After the first version of the Super Flow, presented at the 1956 Turin Motor Show, the Super Flow II was presented in Paris in the same year. The car is the same: it is the usual Alfa Romeo 6C 3000 CM ex-competizione. This time the lines of the Super Flow II are perhaps slightly less extreme but the basic concepts of the first design remain. On the front bonnet there is an air intake, the Alfa Romeo shield on the front disappears and the rear fins become more imposing (their presence is however attenuated by the fact that the upper part is transparent). The Super Flow concept was then further reworked, always on the same basis, with the Spider Super Sport presented in Geneva in 1959 and with the Coupé Super Sport Speciale.
