Bizzarrini S. p. A. was an Italian automotive manufacturer in the 1960s founded by former Alfa Romeo, Ferrari and ISO manufacture, Giotto Bizzarrini. The company built only a few highly developed and innovative sport and racing cars before failing in 1969. Notable models include this 5300 GT Strada and the P538S.Originally Prototipi Bizzarrini azines. r. l., the name was improved to Bizzarrini S. p. A. in 1966.

His father was some sort of rich landowner who originated from a family with powerful roots in Tuscany plus the city of Livorno. His grandfather, also named Giotto Bizzarrini, was a biologist who had caused Guglielmo Marconi on the inventions, especially the radio, following which one from the Livorno Library sections seemed to be named The Bizzarrini Catalogue.Bizzarrini graduated as an engineer in the University of Pisa within 1953. He taught briefly ahead of joining Alfa Romeo throughout 1954. He worked for Alfa Romeo via 1954 to 1957.

Serenissima.One of ATS's financial backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to enhance a Ferrari 250 GT SWB, with chassis number #2819GT to be able to GTO specifications. This resulted in the particular Ferrari 250 GT SWB Drogo often known as the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to style a V-12 engine for the GT car to be built by another discontented Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine to become too highly strung, and ordered that it be detuned.

Bizzarrini worked since 1964 pertaining to Iso Rivolta and produced three models: Iso Rivolta GT, Iso Grifo both A3L along with A3C versions. His work was to develop a pressed steel framework chassis for Iso cars. Renzo Rivolta hired him as consultant towards the Iso Gordon GT venture which became the Iso Rivolta GT. The Iso Gordon GT prototype originated from the Gordon-Keeble. The Gordon Keeble GT had been designed in 1960 by means of Giugiaro. Bizzarrini tested the auto and was impressed from the powerful V8 Corvette engine and the rear De Dion tube useful for the GT:'Rivolta acquired me test the prototype. I liked its De Dion conduit and especially the Corvette engine. It was the first time I had driven one. It was superior to help Ferrari's engines, having the same power but which has a more immediate throttle reply. 'The Iso Rivolta GT was a Giugiaro designed several seater with beautiful system, speed, comfort and handling, and was a productive car for ISO using 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine with a classic De Dion rear suspension design with pushed steel monocoque bodywork around pressed steel frame framework. Unveiled to the mass media in 1963, production continued until 1970.The Iso Grifo A3L was a monstrous idea for a super coupé, the L coming coming from Lusso. The result of this brilliant Giugiaro and Bizzarrini functioning together, it was based with a shortened Iso Rivolta GT framework and was debuted on the 1963 Turin show. The Grifo epitomised the 1960s Italian style using its handsome low and large handmade bodywork. It was the best production car tested by Autocar Magazine in 1966 that has a top speed of 160 mph (260 km/h). Later versions of the particular Grifo were powered by way of a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) engine. These 90 handbuilt units are distinguishable through the raised "pagoda style" information bonnet. Some of these Iso Grifo 7 Litri products were rebuilt later with a great deal larger engines.

The concept of Bizzarrini was to make use of the 3AL cars for rivalry. The competition versions with the Grifo were named Iso Grifo A3C, C for Competizione or Corsa. A new lightweight riveted lightweight alloy body was designed and also built by Piero Drogo. It was an strongly designed machine, oriented to endurance contests. It uses normal ISO underpinnings nevertheless the engine was moved further the government financial aid the chassis frame compared to the Grifo A3L, protruding well into your driver's cabin, fitted with hot cameras and fed by 4 big Weber carburettors, giving more than four hundred bhp (298 kW; 406 PS).

Mini Workshop Manual

All around 29 A3C sport cars were built beneath ISO name. Five of these up to 29 cars were bodied inside plastic/fiberglass by Piero Drogo with Carrozzeria Sports Cars inside Modena. A3Cs were widely raced. Some cars entered the actual 1964 and 1965 Le Mans 24 hour, 1965 Nürburgring 1000 along with 1965 Sebring.
