Bizzarrini Ersus. p. A. was an Italian automotive manufacturer in the 1960s founded by previous Alfa Romeo, Ferrari and ISO electrical engineer, Giotto Bizzarrini. The company built a small number of highly developed and advanced sport and racing cars before failing in 1969. Notable models include the 5300 GT Strada along with the P538S.Originally Prototipi Bizzarrini azines. r. l., the name was changed to Bizzarrini S. p. A. in 1966. The Bizzarrini marque continues to be revived with several concept cars in this 2000s.Giotto Bizzarrini was blessed in Livorno, Italy in 1926. His father was any rich landowner who originated in a family with powerful roots in Tuscany along with the city of Livorno. His grandfather, also named Giotto Bizzarrini, was a biologist who had caused Guglielmo Marconi on his or her inventions, especially the radio, following which one of the Livorno Library sections was named The Bizzarrini Catalogue.Bizzarrini graduated as an engineer within the University of Pisa within 1953. He taught briefly before joining Alfa Romeo inside 1954. He worked for Alfa Romeo via 1954 to 1957. He began working intended for Ferrari in 1957, eventually becoming controller regarding experimental, Sports and GT car or truck development. He worked at Ferrari as a developer, designer, test driver, and chief engineer for five years. His developments there bundled the Ferrari 250 TR, the Ferrari 250 GT SWB (Small Wheelbase Berlinetta or Berlinetta Passo Corto), and the 1962 Ferrari three hundred GTO.

Bizzarrini was fired by Ferrari throughout the "palace revolt" of 1961. He became part connected with Automobili Turismo e Sports activity (ATS)), a company started from the ex-Ferrari engineers to build a Formula 1 single seater and a GT sport car, the A. T. S. Serenissima.One of ATS's financial 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 this Ferrari 250 GT SWB Drogo generally known as the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to pattern a V-12 engine for a GT car to become built by another discontented Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine to become too highly strung, and ordered that this be detuned.

Bizzarrini worked since 1964 regarding Iso Rivolta and formulated three models: Iso Rivolta GT, Iso Grifo both A3L in addition to A3C versions. His work was to develop a pressed steel figure chassis for Iso vehicles. Renzo Rivolta hired him as consultant to the Iso Gordon GT challenge which became the Iso Rivolta GT. The Iso Gordon GT prototype originated from the Gordon-Keeble. The Gordon Keeble GT had been designed in 1960 through Giugiaro. Bizzarrini tested the car and was impressed with the powerful V8 Corvette engine plus the rear De Dion tube used for the GT:'Rivolta acquired me test the prototype. I liked its De Dion conduit 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 reply. 'The Iso Rivolta GT seemed to be a Giugiaro designed some seater with beautiful entire body, 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 raise suspension design with forced steel monocoque bodywork around pressed steel frame chassis. Unveiled to the media in 1963, production continued until 1970.The Iso Grifo A3L has been a monstrous idea for any super coupé, the L coming coming from Lusso. The result of the brilliant Giugiaro and Bizzarrini doing work together, it was based on a shortened Iso Rivolta GT framework and was debuted in the 1963 Turin show. The Grifo epitomised the 1960s Italian style which consists of handsome low and large handmade bodywork. It was the most effective production car tested by means of Autocar Magazine in 1966 which has a top speed of one hundred sixty mph (260 km/h). Later versions of your Grifo were powered by way of a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) powerplant. These 90 handbuilt units are distinguishable with the raised "pagoda style" details bonnet. Some of these Iso Grifo 7 Litri items were rebuilt later with a whole lot larger engines.

Thinking about Bizzarrini was to use the 3AL cars for opposition. The competition versions of the Grifo were named Iso Grifo A3C, C for Competizione or perhaps Corsa. A new lightweight riveted aluminium lightweight body was designed in addition to built by Piero Drogo. It was an strongly designed machine, oriented to endurance backgrounds. It uses normal ISO underpinnings however the engine was moved further in the chassis frame compared to the Grifo A3L, protruding well into the driver's cabin, fitted with hot cams and fed by 4 big Weber carburettors, giving more than four hundred bhp (298 kW; 406 PS).

All-around 29 A3C sport cars were built within the ISO name. Five of these 30 cars were bodied throughout plastic/fiberglass by Piero Drogo on Carrozzeria Sports Cars in Modena. A3Cs were widely competed. Some cars entered this 1964 and 1965 The Mans 24 hour, 1965 Nürburgring 1000 along with 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 of the fastest cars on LeMans' Mulsanne Straight in both years.
