Bizzarrini Utes. p. A. was an Italian automotive manufacturer in the 1960s founded by previous Alfa Romeo, Ferrari and ISO industrial engineer, Giotto Bizzarrini. The company built only a few highly developed and superior sport and racing cars before failing in 1969. Notable models include the actual 5300 GT Strada and the P538S.Originally Prototipi Bizzarrini utes. r. l., the name was modified to Bizzarrini S. p. A. in 1966. The Bizzarrini marque has been revived with many concept cars in the actual 2000s.Giotto Bizzarrini was born in Livorno, Italy in 1926. His father was a new rich landowner who originated from a family with strong roots in Tuscany along with the city of Livorno. His grandfather, also named Giotto Bizzarrini, was a biologist who had worked with Guglielmo Marconi on his / her inventions, especially the radio, following which one on the Livorno Library sections ended up being named The Bizzarrini Library.Bizzarrini graduated as an engineer from the University of Pisa within 1953. He taught briefly before joining Alfa Romeo inside 1954. He worked for Alfa Romeo via 1954 to 1957. He began working intended for Ferrari in 1957, eventually becoming controller associated with experimental, Sports and GT car or truck development. He worked at Ferrari to be a developer, designer, test driver, and chief engineer for five years. His developments there included the Ferrari 250 TR, the Ferrari 250 GT SWB (Quick Wheelbase Berlinetta or Berlinetta Passo Corto), and the 1962 Ferrari 250 GTO.

Bizzarrini seemed to be fired by Ferrari over the "palace revolt" of 1961. He became part regarding Automobili Turismo e Hobby (ATS)), a company started with the ex-Ferrari engineers to create a Formula 1 single seater plus a GT sport car, the A. T. S. Serenissima.One of ATS's personal backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to up grade a Ferrari 250 GT SWB, with chassis number #2819GT to GTO specifications. This resulted in the Ferrari 250 GT SWB Drogo also 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 discontented Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine being too highly strung, and ordered that the idea be detuned.

Bizzarrini worked since 1964 for Iso Rivolta and developed three models: Iso Rivolta GT, Iso Grifo both A3L as well as A3C versions. His work was to develop a pressed steel figure chassis for Iso vehicles. Renzo Rivolta hired him as consultant towards Iso Gordon GT undertaking which became the Iso Rivolta GT. The Iso Gordon GT prototype was made from the Gordon-Keeble. The Gordon Keeble GT had been designed in 1960 by means of Giugiaro. Bizzarrini tested the vehicle and was impressed through the powerful V8 Corvette engine and the rear De Dion tube used for the GT:'Rivolta received me test the prototype. I liked its De Dion pipe and especially the Corvette serps. It was the first-time I had driven just one. It was superior to be able to Ferrari's engines, having the same power but having a more immediate throttle response. 'The Iso Rivolta GT has been a Giugiaro designed four seater with beautiful human body, speed, comfort and handling, and was a profitable car for ISO with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine using a classic De Dion back suspension design with pushed steel monocoque bodywork in excess of pressed steel frame framework. Unveiled to the media in 1963, production continued until 1970.The Iso Grifo A3L had been a monstrous idea for just a super coupé, the L coming coming from Lusso. The result of the brilliant Giugiaro and Bizzarrini operating together, it was based with a shortened Iso Rivolta GT chassis 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 having a top speed of one hundred sixty mph (260 km/h). Later versions of the actual Grifo were powered with a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) engine. These 90 handbuilt units are distinguishable by the raised "pagoda style" scoop bonnet. Some of these Iso Grifo 7 Litri products were rebuilt later with a great deal larger engines.

The concept of Bizzarrini was to utilize 3AL cars for competition. The competition versions from the Grifo were named Iso Grifo A3C, C for Competizione or perhaps Corsa. A new lightweight riveted aluminium body was designed in addition to built by Piero Drogo. It was an in a hostile manner designed machine, oriented to endurance contests. It uses normal ISO underpinnings but the engine was moved further back in the chassis frame compared to Grifo A3L, protruding well into your driver's cabin, fitted with hot cameras and fed by some big Weber carburettors, giving more than 600 bhp (298 kW; 406 PS).

About 29 A3C sport cars were built within the ISO name. Five of these 28 cars were bodied in plastic/fiberglass by Piero Drogo from Carrozzeria Sports Cars in Modena. A3Cs were widely competed. Some cars entered this 1964 and 1965 Le Mans 24 hour, 1965 Nürburgring 1000 and 1965 Sebring. It achieved a Le Mans class win in both years and also a 9th overall in 1965 without any factory support. A3Cs were one from the fastest cars on LeMans' Mulsanne Direct in both years.
