Bizzarrini Utes. p. A. was an Italian automotive manufacturer within the 1960s founded by previous Alfa Romeo, Ferrari and ISO professional, Giotto Bizzarrini. The company built only a few highly developed and advanced sport and racing cars before failing in 1969. Notable models include the actual 5300 GT Strada as well as the P538S.Originally Prototipi Bizzarrini ohydrates. r. l., the name was changed to Bizzarrini S. p. A. in 1966. The Bizzarrini marque has been revived with several concept cars in this 2000s.Giotto Bizzarrini was born in Livorno, Italy in 1926. His father was a new rich landowner who came from a family with strong 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 their inventions, especially the radio, following which one on the Livorno Library sections had been named The Bizzarrini Selection.Bizzarrini graduated as an engineer in the University of Pisa within 1953. He taught briefly before joining Alfa Romeo inside 1954. He worked for Alfa Romeo coming from 1954 to 1957. He began working intended for Ferrari in 1957, eventually becoming controller involving experimental, Sports and GT car or truck development. He worked at Ferrari being a developer, designer, test driver, and chief engineer intended for five years. His developments there bundled the Ferrari 250 TR, the Ferrari 250 GT SWB (Short Wheelbase Berlinetta or Berlinetta Passo Corto), and the 1962 Ferrari 250 GTO.

Bizzarrini was fired by Ferrari during the "palace revolt" of 1961. He became part connected with Automobili Turismo e Activity (ATS)), a company started by the ex-Ferrari engineers to create a Formula 1 single seater and 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 update a Ferrari 250 GT SWB, with chassis number #2819GT for you to GTO specifications. This resulted in the particular Ferrari 250 GT SWB Drogo also called the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to design a V-12 engine for any GT car to possibly be built by another disappointed Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine to get too highly strung, and ordered that this be detuned.
Giotto Bizzarrini and Bizzarrini GT 5300 Background
Bizzarrini worked since 1964 with regard to Iso Rivolta and produced three models: Iso Rivolta GT, Iso Grifo both A3L as well as A3C versions. His work was to develop a pressed steel shape 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 was created from the Gordon-Keeble. The Gordon Keeble GT seemed to be designed in 1960 simply by Giugiaro. Bizzarrini tested the vehicle and was impressed through the powerful V8 Corvette engine along with the rear De Dion tube used for the GT:'Rivolta acquired me test the prototype. I liked its De Dion tubing and especially the Corvette engine. It was the first time I had driven 1. It was superior in order to Ferrari's engines, having the same power but with a more immediate throttle reply. 'The Iso Rivolta GT has been a Giugiaro designed some seater with beautiful human body, speed, comfort and handling, and was a profitable car for ISO having 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine with a classic De Dion raise suspension design with constrained steel monocoque bodywork in excess of pressed steel frame chassis. Unveiled to the press in 1963, production continued until 1970.The Iso Grifo A3L was a monstrous idea for a super coupé, the L coming via Lusso. The result of the actual brilliant Giugiaro and Bizzarrini functioning together, it was based on the shortened Iso Rivolta GT chassis and was debuted in the 1963 Turin show. The Grifo epitomised this 1960s Italian style having its handsome low and wide handmade bodywork. It was the most effective production car tested simply by Autocar Magazine in 1966 with a top speed of 160 mph (260 km/h). Later versions of this Grifo were powered with a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) engine. These 90 handbuilt units are distinguishable because of the raised "pagoda style" details bonnet. Some of these Iso Grifo 7 Litri models were rebuilt later with even bigger engines.

Thinking about Bizzarrini was to utilize the 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 alloy body was designed and also built by Piero Drogo. It was an strongly designed machine, oriented to endurance backgrounds. It uses normal ISO underpinnings but the engine was moved further back in the chassis frame compared to the Grifo A3L, protruding well into this driver's cabin, fitted with hot cams and fed by 4 big Weber carburettors, giving more than 500 bhp (298 kW; 406 PS).

Close to 29 A3C sport cars were built beneath the ISO name. Five of these 29 cars were bodied within plastic/fiberglass by Piero Drogo on Carrozzeria Sports Cars in Modena. A3Cs were widely raced. Some cars entered this 1964 and 1965 Le 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 with the fastest cars on LeMans' Mulsanne Straight in both years.
