Notable models include the 5300 GT Strada as well as the P538S.Originally Prototipi Bizzarrini utes. r. l., the name was altered to Bizzarrini S. p. A. in 1966. The Bizzarrini marque has become revived with quite a few concept cars in the particular 2000s.Giotto Bizzarrini was given birth to in Livorno, Italy in 1926.

Bizzarrini had been fired by Ferrari throughout the "palace revolt" of 1961. He became part regarding Automobili Turismo e Sport (ATS)), a company started with the ex-Ferrari engineers to produce a Formula 1 single seater as well as a GT sport car, the A. T. S. Serenissima.One of ATS's personal backers, Count Giovanni Volpi, owner of Scuderia Serenissima, hired Bizzarrini to enhance a Ferrari 250 GT SWB, with chassis number #2819GT to be able to GTO specifications. This resulted in this Ferrari 250 GT SWB Drogo also called the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to layout a V-12 engine for any GT car to end up being built by another dissatisfied Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine to become too highly strung, and ordered that the idea be detuned.

Bizzarrini worked since 1964 intended for Iso Rivolta and designed three models: Iso Rivolta GT, Iso Grifo both A3L and also A3C versions. His work was in order to develop a pressed steel body chassis for Iso cars. Renzo Rivolta hired him as consultant towards the Iso Gordon GT venture which became the Iso Rivolta GT. The Iso Gordon GT prototype was created from the Gordon-Keeble. The Gordon Keeble GT seemed to be designed in 1960 simply by Giugiaro. Bizzarrini tested the car and was impressed with the powerful V8 Corvette engine and the rear De Dion tube useful for the GT:'Rivolta experienced me test the prototype. I liked its De Dion pipe and especially the Corvette motor. It was the very first time that I had driven one particular. 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 several seater with beautiful physique, speed, comfort and handling, and was a prosperous car for ISO with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine using a classic De Dion raise suspension design with pressed steel monocoque bodywork around pressed steel frame chassis. 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 by Lusso. The result of the particular brilliant Giugiaro and Bizzarrini functioning together, it was based on the shortened Iso Rivolta GT framework and was debuted with the 1963 Turin show. The Grifo epitomised your 1960s Italian style featuring a handsome low and wide handmade bodywork. It was the fastest production car tested by Autocar Magazine in 1966 that has a top speed of one hundred sixty mph (260 km/h). Later versions of the particular Grifo were powered by a big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) serp. These 90 handbuilt units are distinguishable because of the raised "pagoda style" details bonnet. Some of these Iso Grifo 7 Litri units were rebuilt later with a whole lot larger engines.

The idea of Bizzarrini was to utilize the 3AL cars for opposition. The competition versions from the Grifo were named Iso Grifo A3C, C for Competizione or maybe Corsa. A new lightweight riveted aluminium lightweight body was designed as well as built by Piero Drogo. It was an in a hostile manner designed machine, oriented to endurance events. It uses normal ISO underpinnings however the engine was moved further back the chassis frame as opposed to Grifo A3L, protruding well into your driver's cabin, fitted with hot cams and fed by 4 big Weber carburettors, giving more than 600 bhp (298 kW; 406 PS).

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