The Spider MM, with a more compressed engine than the 202, was the result of Giovanni Savonuzzi's joint effort with Pietro Dusio's business. The aluminium body and the tubular chassis made it very light. The engine was based on the ordinary Fiat 1100, but the cylinder block, modified by Dusio, increased so much in power that the MM managed to take the lead in many races. After the 1947 Mille Miglia, it was called "Nuvolari type", to celebrate the victory of the "flying racer from Mantua". At the wheel of an extra-light 202, "Nivola" carried out one of his epic deeds, at the lead of the race as far as Turin, ahead of more powerful cars than his 1100cc. Only along the 240 km motorway to Brescia, slowed down by pouring rain, he had to give way to the Touring compact saloon Alfa Romeo-engined racer - three times as much powerful as his own - driven by Romano Biondetti. However second, he was the true moral victor of that Mille Miglia. Engine: straight-four. Cubic capacity: 1,089cc. Power: 60bhp at 5,800rpm. Maximum speed: 170kph. Feed: induction.
