Bizzarrini Utes. p. A. was an Italian automotive manufacturer inside 1960s founded by past Alfa Romeo, Ferrari and ISO industrial engineer, Giotto Bizzarrini. The company built a small number of highly developed and sophisticated sport and racing vehicles before failing in 1969. Notable models include this 5300 GT Strada and also the P538S.Originally Prototipi Bizzarrini ersus. r. l., the name was modified to Bizzarrini S. p. A. in 1966. The Bizzarrini marque has been revived with several concept cars in your 2000s.Giotto Bizzarrini was delivered in Livorno, Italy in 1926. His father was the 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 in 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 just before joining Alfa Romeo throughout 1954. He worked for Alfa Romeo through 1954 to 1957. He began working regarding Ferrari in 1957, eventually becoming controller of experimental, Sports and GT vehicle development. He worked at Ferrari to be a developer, designer, test driver, and chief engineer regarding 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 250 GTO.

Bizzarrini seemed to be fired by Ferrari over the "palace revolt" of 1961. He became part connected with Automobili Turismo e Sport (ATS)), a company started because of 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 monetary backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to enhance a Ferrari 250 GT SWB, with chassis number #2819GT to help GTO specifications. This resulted in the particular Ferrari 250 GT SWB Drogo also referred to as the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to design and style a V-12 engine for a GT car to end up being built by another dissatisfied Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine being too highly strung, and ordered that the item be detuned.

Bizzarrini worked since 1964 with regard to Iso Rivolta and produced three models: Iso Rivolta GT, Iso Grifo both A3L in addition to A3C versions. His work was to build up a pressed steel body chassis for Iso autos. Renzo Rivolta hired him as consultant on the Iso Gordon GT project 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 by simply Giugiaro. Bizzarrini tested the vehicle and was impressed from the powerful V8 Corvette engine as well as the rear De Dion tube employed for the GT:'Rivolta received me test the prototype. I liked its De Dion tubing and especially the Corvette engine. It was the first time I had driven just one. It was superior to Ferrari's engines, having the same power but using a more immediate throttle response. 'The Iso Rivolta GT seemed to be a Giugiaro designed several seater with beautiful human body, speed, comfort and handling, and was a profitable car for ISO together with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine which has a classic De Dion backside suspension design with hard pressed steel monocoque bodywork over pressed steel frame framework. Unveiled to the press in 1963, production continued until 1970.The Iso Grifo A3L ended up being a monstrous idea for just a super coupé, the L coming via Lusso. The result of the particular brilliant Giugiaro and Bizzarrini working together, it was based using a shortened Iso Rivolta GT chassis and was debuted in the 1963 Turin show. The Grifo epitomised the 1960s Italian style using its handsome low and extensive handmade bodywork. It was the fastest production car tested simply by Autocar Magazine in 1966 with a top speed of 160 mph (260 km/h). Later versions of the Grifo were powered by way of big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) serp. These 90 handbuilt units are distinguishable by the raised "pagoda style" details bonnet. Some of these Iso Grifo 7 Litri products were rebuilt later with a great deal larger engines.

The concept of Bizzarrini was to operate the 3AL cars for levels of competition. The competition versions from the Grifo were named Iso Grifo A3C, C for Competizione or Corsa. A new lightweight riveted alloy body was designed along with built by Piero Drogo. It was an more boldly designed machine, oriented to endurance backgrounds. It uses normal ISO underpinnings but the engine was moved further back the chassis frame as opposed to Grifo A3L, protruding well into your driver's cabin, fitted with hot cams and fed by some big Weber carburettors, giving more than 500 bhp (298 kW; 406 PS).

About 29 A3C sport cars were built within the ISO name. Five of these 30 cars were bodied inside plastic/fiberglass by Piero Drogo on Carrozzeria Sports Cars with Modena. A3Cs were widely ran. Some cars entered your 1964 and 1965 The Mans 24 hour, 1965 Nürburgring 1000 in addition to 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.
