Bizzarrini Ohydrates. p. A. was an Italian automotive manufacturer from the 1960s founded by ex- Alfa Romeo, Ferrari and ISO electrical engineer, Giotto Bizzarrini. The company built a small number of highly developed and sophisticated sport and racing automobiles before failing in 1969. Notable models include the actual 5300 GT Strada and also the P538S.Originally Prototipi Bizzarrini ersus. r. l., the name was changed to Bizzarrini S. p. A. in 1966. The Bizzarrini marque have been revived with a number of concept cars in the actual 2000s.Giotto Bizzarrini was born in Livorno, Italy in 1926. His father was any rich landowner who originated a family with sturdy 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 in the Livorno Library sections ended up being named The Bizzarrini Selection.Bizzarrini graduated as an engineer in the University of Pisa inside 1953. He taught briefly ahead of joining Alfa Romeo throughout 1954. He worked for Alfa Romeo by 1954 to 1957. He began working regarding Ferrari in 1957, eventually becoming controller connected with experimental, Sports and GT auto development. He worked at Ferrari as being 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 (Short Wheelbase Berlinetta or Berlinetta Passo Corto), and the 1962 Ferrari 400 GTO.
Bizzarrini had been fired by Ferrari during 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 develop a Formula 1 single seater as well as a GT sport car, the A. T. S. Serenissima.One of ATS's economic 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 your Ferrari 250 GT SWB Drogo also called the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to design a V-12 engine for just a GT car to become built by another discontented Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine for being too highly strung, and ordered that this be detuned.

Bizzarrini worked since 1964 for Iso Rivolta and produced three models: Iso Rivolta GT, Iso Grifo both A3L in addition to A3C versions. His work was to develop a pressed steel frame chassis for Iso cars and trucks. Renzo Rivolta hired him as consultant for the Iso Gordon GT task which became the Iso Rivolta GT. The Iso Gordon GT prototype originated from the Gordon-Keeble. The Gordon Keeble GT ended up being designed in 1960 by simply Giugiaro. Bizzarrini tested the vehicle and was impressed by the powerful V8 Corvette engine along with the rear De Dion tube for the GT:'Rivolta got me test the prototype. I liked its De Dion tube and especially the Corvette powerplant. It was the very first time that I had driven just one. It was superior for you to Ferrari's engines, having the same power but using a more immediate throttle reply. 'The Iso Rivolta GT ended up being a Giugiaro designed some seater with beautiful physique, speed, comfort and handling, and was a productive car for ISO having 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine which has a classic De Dion backside suspension design with pressed steel monocoque bodywork over pressed steel frame chassis. Unveiled to the click in 1963, production continued until 1970.The Iso Grifo A3L had been a monstrous idea for the super coupé, the L coming through Lusso. The result of the actual brilliant Giugiaro and Bizzarrini doing work together, it was based with a shortened Iso Rivolta GT chassis and was debuted at the 1963 Turin show. The Grifo epitomised the particular 1960s Italian style having its handsome low and extensive handmade bodywork. It was the best production car tested by simply Autocar Magazine in 1966 using a top speed of one hundred sixty mph (260 km/h). Later versions of the particular Grifo were powered by way of a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) serps. 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 even bigger engines.
The thinking behind Bizzarrini was to use 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 aluminium lightweight body was designed along with built by Piero Drogo. It was an boldy designed machine, oriented to endurance races. It uses normal ISO underpinnings but the engine was moved further the government financial aid the chassis frame as opposed to Grifo A3L, protruding well into the particular driver's cabin, fitted with hot cams and fed by several big Weber carburettors, giving more than 400 bhp (298 kW; 406 PS).

Around 29 A3C sport cars were built beneath the ISO name. Five of these up to 29 cars were bodied in plastic/fiberglass by Piero Drogo from Carrozzeria Sports Cars in Modena. A3Cs were widely competed. Some cars entered the particular 1964 and 1965 The 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 with the fastest cars on LeMans' Mulsanne Direct in both years.
