Bizzarrini S. p. A. was an Italian automotive manufacturer within the 1960s founded by ex- Alfa Romeo, Ferrari and ISO professional, Giotto Bizzarrini. The company built a small number of highly developed and innovative sport and racing cars before failing in 1969. Notable models include this 5300 GT Strada and the P538S.Originally Prototipi Bizzarrini utes. r. l., the name was altered to Bizzarrini S. p. A. in 1966. The Bizzarrini marque may be revived with quite a few concept cars in the 2000s.Giotto Bizzarrini was blessed in Livorno, Italy in 1926. His father was some sort of rich landowner who originated from a family with solid 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 his / her inventions, especially the radio, following which one of the Livorno Library sections had been named The Bizzarrini Stockpile.Bizzarrini graduated as an engineer inside the University of Pisa in 1953. He taught briefly prior to joining Alfa Romeo with 1954. He worked for Alfa Romeo via 1954 to 1957. He began working regarding Ferrari in 1957, eventually becoming controller regarding experimental, Sports and GT car development. He worked at Ferrari as a developer, designer, test driver, and chief engineer regarding five years. His developments there involved the Ferrari 250 TR, the Ferrari 250 GT SWB (Small Wheelbase Berlinetta or Berlinetta Passo Corto), and the 1962 Ferrari 250 GTO.

Bizzarrini ended up being fired by Ferrari during the "palace revolt" of 1961. He became part associated with Automobili Turismo e Sports activity (ATS)), a company started by the ex-Ferrari engineers to create a Formula 1 single seater and also 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 for you to GTO specifications. This resulted in the actual Ferrari 250 GT SWB Drogo also called the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to pattern a V-12 engine for a GT car to possibly be built by another not satisfied Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine being too highly strung, and ordered that this be detuned.

Bizzarrini worked since 1964 for Iso Rivolta and developed three models: Iso Rivolta GT, Iso Grifo both A3L and also A3C versions. His work was to develop a pressed steel body chassis for Iso cars. Renzo Rivolta hired him as consultant on the Iso Gordon GT challenge which became the Iso Rivolta GT. The Iso Gordon GT prototype got its start from the Gordon-Keeble. The Gordon Keeble GT was designed in 1960 through Giugiaro. Bizzarrini tested the vehicle and was impressed from the powerful V8 Corvette engine and the rear De Dion tube used by the GT:'Rivolta received me test the prototype. I liked its De Dion pipe and especially the Corvette powerplant. It was the very first time I had driven one particular. It was superior for you to Ferrari's engines, having the same power but having a more immediate throttle answer. 'The Iso Rivolta GT had been a Giugiaro designed 4 seater with beautiful human body, speed, comfort and handling, and was a successful 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 in excess of pressed steel frame framework. Unveiled to the press in 1963, production continued until 1970.The Iso Grifo A3L had been a monstrous idea for just a super coupé, the L coming from Lusso. The result of your brilliant Giugiaro and Bizzarrini operating together, it was based using a shortened Iso Rivolta GT chassis and was debuted on the 1963 Turin show. The Grifo epitomised this 1960s Italian style having its handsome low and broad handmade bodywork. It was the fastest production car tested through Autocar Magazine in 1966 using a top speed of 160 mph (260 km/h). Later versions of your Grifo were powered by the big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) engine. These 90 handbuilt units are distinguishable through the raised "pagoda style" deal bonnet. Some of these Iso Grifo 7 Litri devices were rebuilt later with a great deal larger engines.

The concept of Bizzarrini was to utilize 3AL cars for rivalry. The competition versions on 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 more boldly designed machine, oriented to endurance backrounds. It uses normal ISO underpinnings though the engine was moved further last the chassis frame versus Grifo A3L, protruding well into the particular driver's cabin, fitted with hot cameras and fed by some big Weber carburettors, giving more than 500 bhp (298 kW; 406 PS).

Mini Workshop Manual

Around 29 A3C sport cars were built beneath the ISO name. Five of these 30 cars were bodied in plastic/fiberglass by Piero Drogo on Carrozzeria Sports Cars in Modena. A3Cs were widely ran. Some cars entered the actual 1964 and 1965 Le Mans 24 hour, 1965 Nürburgring 1000 and also 1965 Sebring. It achieved a Le Mans class win in both years plus a 9th overall in 1965 without having factory support. A3Cs were one on the fastest cars on LeMans' Mulsanne Directly in both years.
