The Airone is a Moto Guzzi motorcycle in production between 1939 and 1957. Presented at the end of 1939 as heir to the P.E. 250, the new quarter-liter Mandellese was equipped with a four-speed gearbox (against the ancestors' three) and an engine driven at 246 cm³ (9.5 hp maximum power, 95 km/h). Initially equipped with a frame in tubes, shortly after being sold, this was replaced by one made of pressed sheet metal, cheaper to produce. Returned to production in 1945, after the Second World War, in 1947 it was updated in suspensions with the adoption of a telescopic fork designed by Carlo Guzzi in person and a pair of rear hydraulic shock absorbers, while at the end of 1948 a headboard was introduced in aluminum with enclosed distribution parts. In 1949 the Airone Sport was marketed, with an engine boosted to 13.5 hp (120 km/h top speed) thanks to a new camshaft, a Dell'Orto SS 25 carburetor and a more collected combustion chamber. The chassis has also been revised, with the rear part of the frame in tubes, larger diameter aluminum drum brakes, lightened design mudguards and adjustable rear calipers. Since 1951 the Sport's chassis, rear suspension and brakes were also used on the tourist version. In 1954 a new muffler was introduced, quieter than the previous one: the performance of the Sport was affected, falling to 12 hp and 110 km/h. In 1956 the Sport came out of production, while it remained on the list for another year (especially for military supplies, for which Moto Guzzi had prepared an ad hoc version of Airone in 1952) the Tourism version.

![Alfa Romeo 8c 2900 B Speciale Le Mans - 1938
The Alfa Romeo 8C name was used on road, race and sports cars of the 1930s. The 8C means 8 cylinders, and originally referred to a straight 8-cylinder engine. The Vittorio Jano designed 8C was Alfa Romeos primary racing engine from its introduction in 1931 to its retirement in 1939. In addition to the two-seater sports cars it was used in the worlds first genuine single-seat Grand Prix racing car, the Monoposto Tipo B - P3 from 1932 onwards. In its later development it powered such vehicles as the twin-engined 1935 6.3-litre Bimotore, the 1935 3.8-litre Monoposto 8C 35 Type C, and the Alfa Romeo 8C 2900B Mille Miglia Roadster. It also powered top-of-the-range coach-built production models. In 2004 Alfa Romeo revived the 8C name for a V8-engined concept car which has made it into production for 2007, the Alfa Romeo 8C Competizione. Alfa Corse also prepared and entered a single 8C 2900B, chassis number 412033, for the 1938 Le Mans. The car featured a streamlined coupé body at a time when Le Mans racers were almost always open cars.[citation needed] The aerodynamic coupé was built by Carrozzeria Touring. In 1987, an Italian magazine had the car tested at the Pininfarina wind tunnel, where a Cx of 0.42 was measured, down to 0.38 with air intakes closed. The coupé, driven by Sommer and Biondetti, led for most of the race, but tyre trouble was then followed by a dropped valve. The car was driven to the pits, but had to retire there. At the time the valve dropped, the coupé had a lead of more than 160 km over the next car. This was the only time the coupé was raced by Alfa Corse. After the war, it was entered in minor races under private ownership, was then displayed at the Donington museum from the 1960s before being added in 1987 to the Alfa Romeo museum, which now runs it at many events.
