Porter Press InternationalIso Bizzarrini The remarkable history of

Bizzarrini Azines. p. A. was an Italian automotive manufacturer inside the 1960s founded by previous Alfa Romeo, Ferrari and ISO industrial engineer, Giotto Bizzarrini. The company built only a few highly developed and superior sport and racing autos before failing in 1969. Notable models include the 5300 GT Strada along with the P538S.Originally Prototipi Bizzarrini azines. r. l., the name was transformed to Bizzarrini S. p. A. in 1966. The Bizzarrini marque have been revived with many concept cars in your 2000s.Giotto Bizzarrini was born in Livorno, Italy in 1926. His father was some sort of rich landowner who originated from a family with strong roots in Tuscany as well as the city of Livorno. His grandfather, also named Giotto Bizzarrini, was a biologist who had worked with Guglielmo Marconi on his / her inventions, especially the radio, following which one on the Livorno Library sections had been named The Bizzarrini Catalogue.Bizzarrini graduated as an engineer from the University of Pisa inside 1953. He taught briefly just before joining Alfa Romeo inside 1954. He worked for Alfa Romeo from 1954 to 1957. He began working intended for Ferrari in 1957, eventually becoming controller associated with experimental, Sports and GT car development. He worked at Ferrari as a developer, designer, test driver, and chief engineer with regard to five years. His developments there incorporated the Ferrari 250 TR, the Ferrari 250 GT SWB (Short Wheelbase Berlinetta or Berlinetta Passo Corto), and the 1962 Ferrari 400 GTO.

Bizzarrini seemed to be fired by Ferrari in the "palace revolt" of 1961. He became part associated with Automobili Turismo e Sport (ATS)), a company started because of 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 economic backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to improve a Ferrari 250 GT SWB, with chassis number #2819GT for you 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 layout a V-12 engine to get a GT car to possibly be built by another dissatisfied Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine to be too highly strung, and ordered that that be detuned.

Bizzarrini worked since 1964 for Iso Rivolta and produced three models: Iso Rivolta GT, Iso Grifo both A3L and A3C versions. His work was to produce a pressed steel figure 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 was made from the Gordon-Keeble. The Gordon Keeble GT seemed to be designed in 1960 by simply Giugiaro. Bizzarrini tested the automobile and was impressed because of the powerful V8 Corvette engine and also the rear De Dion tube for the GT:'Rivolta had me test the prototype. I liked its De Dion tubing and especially the Corvette serp. It was the very first time I had driven one. It was superior to be able to Ferrari's engines, having the same power but which has a more immediate throttle response. 'The Iso Rivolta GT had been a Giugiaro designed 4 seater with beautiful human body, speed, comfort and handling, and was a prosperous car for ISO using 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine that has a classic De Dion backed suspension design with constrained steel monocoque bodywork over pressed steel frame chassis. Unveiled to the media in 1963, production continued until 1970.The Iso Grifo A3L seemed to be a monstrous idea for just a super coupé, the L coming from Lusso. The result of the actual brilliant Giugiaro and Bizzarrini working together, it was based on the shortened Iso Rivolta GT framework and was debuted on the 1963 Turin show. The Grifo epitomised the actual 1960s Italian style using its handsome low and extensive handmade bodywork. It was the quickest production car tested by means of Autocar Magazine in 1966 using a top speed of 160 mph (260 km/h). Later versions of the Grifo were powered by the big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) motor. These 90 handbuilt units are distinguishable by the raised "pagoda style" information bonnet. Some of these Iso Grifo 7 Litri devices were rebuilt later with even bigger engines.

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

Around 29 A3C sport cars were built beneath ISO name. Five of these 30 cars were bodied throughout plastic/fiberglass by Piero Drogo at Carrozzeria Sports Cars within Modena. A3Cs were widely competed. Some cars entered this 1964 and 1965 Le Mans 24 hour, 1965 Nürburgring 1000 as well as 1965 Sebring. It achieved a The Mans class win in both years as well as a 9th overall in 1965 without any factory support. A3Cs were one on the fastest cars on LeMans' Mulsanne Immediately in both years.
