The Alfa Romeo 2600 Sprint Zagato (SZ) was presented by Alfa Romeo In 1963.
At the Salon de Geneve, in March 1962, An evolution of the 2000 range is unveiled in the form of the sedan 2600, which will be produced until 1968.In 1963 Zagato presented the prototype of its interpretation of the 2600, designed by Ercole Spada, with an aerodynamic line that could be recognized from the front end fitted with elliptical-shaped headlights and a particularly large Alfa Romeo trilobe, it was distinguishable by the particularly original lines that recall the contemporary Zagato style, making it similar to a Lancia Flaminia Super Sport.
The car was put into production only in 1965 and produced for only two years, with only 105 units built until 1967. In 1962, Carrozzeria Pininfarina presented its proposal for the nascent 2600 series. First it presented a sedan, then it created a red spider and, transforming the same car, an emerald green coupé. With integral chassis the front suspension as independent, wishbones, coil springs,anti-roll bar, with telescopic dampers at the rear rigid axle, trailing lower radius arms, transverse linkage bars, coil springs and telescopic dampers.
The 2600 Spider Speciale was presented at the 1962 Turin and Geneva Motor Shows, painted red, characterized by a clean and elegant line, with retractable headlights and a very special shield in which the Visconti snake and the Milan cross of the small round emblem they grow larger to occupy the entire Alfa Romeo trefoil, as already seen on their only sedan ever made. The car was later transformed into the 2600 Coupé Speciale presented at the Brussels Motor Show in January 1963, also equipped with other aesthetic changes, including the change of colour from red to green and the adoption of spoked wheels. After having lost track of it over the years, it was rediscovered in the United States and restored according to the specifications of the Brussels Motor Show.
The 2600 SZs are very rare with only 105 cars produced today they are by far the most valuable model in the 2600 range.
