Campini-Caproni CC.2
Il Campini-Caproni CC.2 (secondo prototipo, ma primo ad essere completato) fu il primo aereo con propulsione a jet costruito in Italia, ed uno dei primi al mondo. Effettuò il primo volo nell'agosto 1940. Il giudizio sul propulsore è duplice. Da un lato esso non era tecnicamente avanzato, e neanche con elevate prospettive di sviluppo. Dall'altro, però, per la prima volta incorporava un compressore assiale a tre stadi, e, soprattutto, un post-bruciatore che costituiva un notevole avanzamento sul piano tecnico. Per questo, il Campini-Caproni ha comunque notevolmente contribuito allo sviluppo della tecnologia aeronautica.
Il Campini-Caproni esposto a Vigna di Valle è il secondo prototipo (ma primo a volare), ossia il CC.2.

The Campini-Caproni CC.2 (second prototype, but first to flight) was the first jet aircraft built in Italy, and the third in the world, just after Heinkel He 176 (a rocket plane that flew in June 1939) and Heinkel 178 (a turbo-jet with a centrifugal compressor that flew in August 1939). CC.2 first flew in August 1940. A technical judgment about the powerplant of CC.2 is necessarily twofold. On one hand, it was not technically advanced, because the compressor was operated by a piston engine, and not by a turbine. On the other hand, its three-stage compressor, and mainly its after-burner, were technically innovative. For this reason, the Campini-Caproni significantly contributed to the development of aviation technology.
The Campini-Caproni on display at Vigna di valle Museum is CC.2, namely the second prototype (but first to flight).

The Alfa Romeo 6C name was used on road, race and sports cars made between 1925–1954 by Alfa Romeo. 6C refers to a straight 6 engine. Bodies for these cars were made by coachbuilders such as James Young, Zagato, Touring, Castagna, and Pininfarina. Starting from 1933 there was also a 6C version with a factory Alfa body, built in Portello.
In the mid-1920s, Alfa's RL was considered too large and heavy, so a new development began. The 2-liter formula that had led to Alfa Romeo winning the World Championship in 1925, changed to 1.5 liter for the 1926 season. The 6C1500 was introduced in 1925 at Milan, production started 1927, with the P2 Grand Prix car as starting point. Engine capacity was now 1487 cc, against the P2's 1987 cc, while supercharging was dropped. First versions were bodied by Young and Touring.
In 1928, a 6C Sport was released, with a dual overhead camshafts engine. Its sport version won many races, including the 1928 Mille Miglia. Total production was 3000 (200 with DOHC engine). Ten copies of a supercharged (compressore, compressor) Super Sport variant were also made.
Variants:
6C 1500, 44 bhp @ 4400 rpm, 109 km/h (68 mph) (1925–1929)
6C 1500 Sport, 54 bhp @ 4500 rpm, 125 km/h (78 mph) (1928–1929)- 171 cars
6C 1500 Super Sport compressore, 76 bhp @ 4800 rpm, 140 km/h (87 mph) (1928–1929)
6C 1500 TF, 84 bhp @ 5000 rpm (1928–1929)
