In great part because of my initiative and planning all these people had congregated at Sebring for what

172-469: 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 upgrade a Ferrari 250 GT SWB, with chassis number #2819GT 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

215-442: A Le Mans class win in both years and a 9th overall in 1965 with no factory support. A3Cs were one of the fastest cars on Le Mans' Mulsanne Straight in both years. Due to the complicated deal with Iso, Bizzarrini left in 1964 and founded Societa Prototipi Bizzarrini (Bizzarrini S.p. A), which produced some 140 cars through 1969 at its Livorno factory. Giotto Bizzarrini was a dedicated race car designer and builder. Likely one of

Lamborghini considered the resulting engine to be too highly strung, and ordered that it be detuned. Bizzarrini worked since 1964 for Iso Rivolta and developed three models: Iso Rivolta GT, Iso Grifo both A3L and A3C versions. His work was to develop a pressed steel frame chassis for Iso cars. Renzo Rivolta hired him as consultant to

Weber carburetors are marked with a model code on the mounting flange, the body, or on the cover of the float chamber. This begins with a number which originally indicated the diameter (in millimetres) of the throttle bore, but later lost this significance. If this number has

387-492: A carbon fiber body. The car was shown to the public for the first time at Pebble Beach in 1993. It was designed by a team led by car designer Barry Watkins, with the design being inspired by the Bizzarrini 5300 GT Spyder, although it is also considered to be the true successor to the P538. About 3 million dollars was invested to build the car, an astronomical amount for that time. The car was planned to be put in production, but it remained

The company was established as Fabbrica Italiana Carburatori Weber in 1923 when Weber produced carburetors as part of a conversion kit for Fiats . Weber pioneered the use of two-stage twin-barrel carburetors, with two venturis of different sizes (the smaller one for low-speed/rpm running and

516-463: A dozen (or more) chassis are in existence, some of these replicas claiming to be the real cars raced in Le Mans. At least two of the replicas are Lamborghini V12 powered. These V12 powered cars were truly the long-awaited Bizzarrini dream — his own engine and chassis. In 1990, Bizzarrini was involved in the design of a one-off supercar model based on Ferrari Testarossa chassis and running gear with

These numbers are followed by a group of letters, which indicate various features: the DCOE is a sidedraft unit, all others being downdraft;

602-573: A spin at the start line, it lasted less than a half an hour and retired due to a cracked oil line. During the short race time, the P538 was clocked as one of the fastest cars on the Mulsanne Straight. In 1968, Giugiaro rebuilt one of the P538 bodies as the Bizzarrini Manta . After some years in Sweden , it was dismantled for an extensive restoration. Later featured in various classics car events, it

Bizzarrini's advanced ideas emerged again with the Bizzarrini P538S , P for posteriore, 53 for the 5300 cc Corvette engine, 8 for V8 engine and S for Sports car. The first V-12 car was ordered by American racer Mike Gammino . This Barchetta raced in the 1966 Le Mans (DNF) and was even entered in 1967, but did not start (DNQ). In 1966, after

731-538: Is now in the United States. Seven complete AMC AMX/3 cars and nine chassis are known to survive. Some remaining parts from the canceled, second group of five cars were used by erstwhile Bizzarrini collaborator Salvatore Diomante to assemble the sixth car, named and marketed as Sciabola. Bizzarrini used the 8th AMX/3 chassis to build the Iso Varedo. Additionally, an open two-seat Spider featuring no weather protection

Rino Argento helped Bizzarrini manage the race cars during that terrible week in June 1965 at Sebring. He has written a detailed account of that week, which was originally published in the Griffon, the magazine of the Iso & Bizzarrini Owner's Club. Car No. 8, driven by Silvio Moser, went off track due to brake failure and crashed into

860-521: The Bizzarrini team. He took all of the pieces of these two Iso/Bizzarrini race cars back to his shop in Southern California with the intention to build one Iso/Bizzarrini from the pieces of the two destroyed cars. This recreated Iso/Bizzarrini race car has never been seen again. There was a morbid end to the week: a plane crash killed Iso and Bizzarrini supporter Mitch Michelmore and his son as they were on their way back to California. Michelmore "had

Most of these copies are manufactured in China, and being direct copies means that parts are at least meant to be interchangeable. Operation however, usually varies from the original, due to inaccurate drilling and poorly calibrated parts and use of different quality materials. If there

Nevertheless, their motivation was so strong that, after a short briefing of about half an hour, they presented an alternative proposal — to construct a sports car.

1505-564: The sources of disagreement between Renzo Rivolta and Giotto Bizzarrini was Bizzarrini's desire to build race cars and Renzo Rivolta's desire to build high quality GT cars and family transportation cars. They decided to part ways in 1964. Bizzarrini had mixed success in racing. The lowlight for Bizzarrini must certainly have been the Sebring 12 Hours on March 27, 1965, where both Iso/Bizzarrini race cars crashed causing serious damage, placing them beyond repair. The highlight came later that same year at

Later versions of the Grifo were powered by a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) engine. These 90 handbuilt units are distinguishable by the raised "pagoda style" scoop bonnet. Some of these Iso Grifo 7 Litri units were rebuilt later with even bigger engines. The idea of Bizzarrini

The body shape and mechanical parts were much the same as the Iso A3Cs, resulting in a coupe that is 43 inches (1.09 m) in height. Only three Bizzarrini GT 5300s Spyder S.I were built starting in 1966, Under Ing Giotto Bizzarrini supervision were turned out by Stile Italia (S.I) D'Iseglio -Ex Engineer of (Berton) and Sibona e Basano (SB) Ex-Chief Metalsmith & Ex Mold maker (Ghia).
