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

Bizzarrini seemed to be fired by Ferrari in the "palace revolt" of 1961. He became part of Automobili Turismo e Sport (ATS)), a company started through the ex-Ferrari engineers to develop a Formula 1 single seater plus 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 in order 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 to get a GT car to become built by another dissatisfied Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine being too highly strung, and ordered that that be detuned.

Bizzarrini worked since 1964 regarding Iso Rivolta and created three models: Iso Rivolta GT, Iso Grifo both A3L along with A3C versions. His work was to formulate a pressed steel shape chassis for Iso automobiles. 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 has been designed in 1960 by means of Giugiaro. Bizzarrini tested the car and was impressed from the powerful V8 Corvette engine and the rear De Dion tube useful for the GT:'Rivolta had me test the prototype. I liked its De Dion tubing and especially the Corvette motor. It was the first-time I had driven a single. It was superior to be able to Ferrari's engines, having the same power but having a more immediate throttle reaction. 'The Iso Rivolta GT was a Giugiaro designed 4 seater with beautiful physique, speed, comfort and handling, and was a effective car for ISO along with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine with a classic De Dion backed suspension design with pressed steel monocoque bodywork around pressed steel frame framework. Unveiled to the mass media in 1963, production continued until 1970.The Iso Grifo A3L seemed to be a monstrous idea for a super coupé, the L coming by Lusso. The result of the brilliant Giugiaro and Bizzarrini functioning together, it was based on the shortened Iso Rivolta GT framework and was debuted for the 1963 Turin show. The Grifo epitomised the particular 1960s Italian style featuring a handsome low and broad handmade bodywork. It was the quickest production car tested by Autocar Magazine in 1966 having a top speed of 160 mph (260 km/h). Later versions of the particular Grifo were powered with a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) serps. These 90 handbuilt units are distinguishable from the raised "pagoda style" deal bonnet. Some of these Iso Grifo 7 Litri items were rebuilt later with even bigger engines.

The thought of Bizzarrini was to make use of the 3AL cars for opposition. The competition versions on the Grifo were named Iso Grifo A3C, C for Competizione or even Corsa. A new lightweight riveted aluminium body was designed and built by Piero Drogo. It was an aggressively designed machine, oriented to endurance events. It uses normal ISO underpinnings however the engine was moved further back the chassis frame versus Grifo A3L, protruding well into this driver's cabin, fitted with hot cams and fed by a number of big Weber carburettors, giving more than 500 bhp (298 kW; 406 PS).

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