The Bizzarrini Strada (also 5300 GT Strada and 5300 GT), is a sports car produced by Bizzarrini from 1964 to 1968. Sold as a low slung, two-seat coupé, roadster, and track-tuned "Corsa" racer, it proved to be Bizzarrini's most successful model.
History
Designed by ex-Ferrari chief engineer Giotto Bizzarrini in 1963, the Strada was launched by his company in 1964. It was similar in concept to the Iso Grifo, also designed by Bizzarrini, and even used the Grifo name while in the planning stage, as well as the welded unibody platform of the Iso Rivolta 300.
Spyder
The Bizzarrini 5300 GT S.I. Spyder was a series of three cars created in 1966 based on the Strada Chassis. They were designed under Ing. Giotto Bizzarrini supervision by mostly unknown carrozzeria Stile Italia (S.I.), D'Iseglio -Ex Engineer of (Berton) on via Governolo 28 in Torino, and built in cooperation with Sibona & Basano (SB) Ex-Chief Metalsmith & Ex Mold maker (Ghia) . The name Spyder had an "y" in it for marketing reasons, because it is not part of the Italian alphabet. The first appearance was at the Geneva Motor Show in 1966, after a traffic accident of the transporter who brought the car(s) to the show. Of the three Spyders built, one (the prototype) is painted silver where it is featured as the only (Prototype) automobile offered as a Coupe, Targa and is a full convertible Roadster, while the other two feature removable T-tops with a center bar running through the middle of the roof. The engine was a Chevrolet 327 V8 with four Weber carburetors. The Spyders also have other modifications to the bodywork, including subtly redesigned front ends and larger luggage compartments. A series of 100 examples had been planned, but only two found buyers.
