Bizzarrini S. p. A. was an Italian automotive manufacturer inside the 1960s founded by former Alfa Romeo, Ferrari and ISO professional, Giotto Bizzarrini. The company built few highly developed and sophisticated sport and racing cars before failing in 1969. Notable models include the 5300 GT Strada and the P538S.Originally Prototipi Bizzarrini azines. r. l., the name was modified to Bizzarrini S. p. A. in 1966. The Bizzarrini marque have been revived with many concept cars in this 2000s.Giotto Bizzarrini was created in Livorno, Italy in 1926. His father was a rich landowner who originated from a family with sturdy roots in Tuscany and also the city of Livorno. His grandfather, also named Giotto Bizzarrini, was a biologist who had worked with Guglielmo Marconi on the inventions, especially the radio, following which one from the Livorno Library sections had been named The Bizzarrini Catalogue.Bizzarrini graduated as an engineer in the University of Pisa within 1953. He taught briefly before joining Alfa Romeo with 1954. He worked for Alfa Romeo by 1954 to 1957. He began working for Ferrari in 1957, eventually becoming controller of experimental, Sports and GT automobile development. He worked at Ferrari like a developer, designer, test driver, and chief engineer with regard to five years. His developments there involved the Ferrari 250 TR, the Ferrari 250 GT SWB (Brief Wheelbase Berlinetta or Berlinetta Passo Corto), and the 1962 Ferrari 300 GTO.
Bizzarrini ended up being fired by Ferrari during the "palace revolt" of 1961. He became part associated with Automobili Turismo e Game (ATS)), a company started through the ex-Ferrari engineers to produce a Formula 1 single seater as well as a GT sport car, the A. T. S. Serenissima.One of ATS's fiscal backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to up grade a Ferrari 250 GT SWB, with chassis number #2819GT to help GTO specifications. This resulted in the actual Ferrari 250 GT SWB Drogo generally known as the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to design a V-12 engine for a GT car to end up being built by another not satisfied Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine for being too highly strung, and ordered that the idea be detuned.
Bizzarrini worked since 1964 intended for Iso Rivolta and designed three models: Iso Rivolta GT, Iso Grifo both A3L and also A3C versions. His work was in order to develop a pressed steel frame chassis for Iso vehicles. Renzo Rivolta hired him as consultant on the Iso Gordon GT undertaking which became the Iso Rivolta GT. The Iso Gordon GT prototype was developed 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 as well as the rear De Dion tube used for the GT:'Rivolta received me test the prototype. I liked its De Dion tubing and especially the Corvette engine. It was the very first time that I had driven just one. It was superior to help Ferrari's engines, having the same power but having a more immediate throttle answer. 'The Iso Rivolta GT was a Giugiaro designed several seater with beautiful entire body, speed, comfort and handling, and was a productive car for ISO along with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine using a classic De Dion backed suspension design with constrained steel monocoque bodywork in excess of pressed steel frame framework. Unveiled to the media in 1963, production continued until 1970.The Iso Grifo A3L ended up being a monstrous idea to get a super coupé, the L coming coming from Lusso. The result of your brilliant Giugiaro and Bizzarrini functioning together, it was based on the shortened Iso Rivolta GT framework and was debuted with the 1963 Turin show. The Grifo epitomised your 1960s Italian style with its handsome low and vast handmade bodywork. It was the quickest production car tested by simply Autocar Magazine in 1966 with a top speed of one hundred sixty mph (260 km/h). Later versions of your Grifo were powered by a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) serp. These 90 handbuilt units are distinguishable by the raised "pagoda style" deal bonnet. Some of these Iso Grifo 7 Litri units were rebuilt later with a whole lot larger engines.

The concept of Bizzarrini was to operate the 3AL cars for levels of competition. The competition versions in the Grifo were named Iso Grifo A3C, C for Competizione or maybe Corsa. A new lightweight riveted alloy body was designed and also built by Piero Drogo. It was an boldy designed machine, oriented to endurance contests. It uses normal ISO underpinnings but the engine was moved further last the chassis frame than the Grifo A3L, protruding well into the driver's cabin, fitted with hot cams and fed by some big Weber carburettors, giving more than 400 bhp (298 kW; 406 PS).
Close to 29 A3C sport cars were built underneath the ISO name. Five of these twenty nine cars were bodied throughout plastic/fiberglass by Piero Drogo at Carrozzeria Sports Cars in Modena. A3Cs were widely raced. Some cars entered this 1964 and 1965 The Mans 24 hour, 1965 Nürburgring 1000 and also 1965 Sebring. It achieved a Le Mans class win in both years as well as a 9th overall in 1965 without the need of factory support. A3Cs were one on the fastest cars on LeMans' Mulsanne Straight in both years.
