The 1961 Michelotti-Conrero prototype Giulietta "a goccia” (“drop”) weighed about kg 750 and its frame was not the last type produced by the Portello Alfa Romeo plants, but the 1957 version, since – in order to build the new body – a Giulietta Sprint Veloce had been undressed. After an appropriate mechanical preparation by Conrero, the engine developed 125 hp at 7400 revs/min, with a maximum torque of 13.2 kgm at 5000 revs/min. The maximum speed reached by this Giulietta was in the order of 222 km/h (recorded at Monza autodrome), despite the fact that the car was only a four speed version (Source)
