Notable models include the 5300 GT Strada plus the P538S.Originally Prototipi Bizzarrini s. r. l., the name was altered to Bizzarrini S. p. A. in 1966. The Bizzarrini marque has been revived with a number of concept cars in the actual 2000s.Giotto Bizzarrini was delivered in Livorno, Italy in 1926. His father was any rich landowner who got their start in a family with solid roots in Tuscany as well as the city of Livorno.

Bizzarrini was fired by Ferrari throughout the "palace revolt" of 1961. He became part associated with Automobili Turismo e Activity (ATS)), a company started from the ex-Ferrari engineers to create a Formula 1 single seater as well as 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 upgrade a Ferrari 250 GT SWB, with chassis number #2819GT to help GTO specifications. This resulted in the actual Ferrari 250 GT SWB Drogo often known as the "Breadvan".Bizzarrini's engineering company, Societa Autostar, was commissioned to design and style a V-12 engine for just a GT car to always be built by another not satisfied Ferrari customer, Ferruccio Lamborghini. Lamborghini considered the resulting engine to get too highly strung, and ordered that the idea be detuned.

Bizzarrini worked since 1964 for Iso Rivolta and designed three models: Iso Rivolta GT, Iso Grifo both A3L as well as A3C versions. His work was to formulate a pressed steel framework chassis for Iso cars and trucks. Renzo Rivolta hired him as consultant for the Iso Gordon GT project which became the Iso Rivolta GT. The Iso Gordon GT prototype was made from the Gordon-Keeble. The Gordon Keeble GT has been designed in 1960 by means of Giugiaro. Bizzarrini tested the vehicle and was impressed through the powerful V8 Corvette engine and also the rear De Dion tube for the GT:'Rivolta experienced me test the prototype. I liked its De Dion tube and especially the Corvette powerplant. It was the very first time that I had driven a single. It was superior in order to Ferrari's engines, having the same power but that has a more immediate throttle reply. 'The Iso Rivolta GT seemed to be a Giugiaro designed some seater with beautiful physique, speed, comfort and handling, and was a effective car for ISO together with 799 units sold. Powered by a 327ci Chevrolet Corvette V8 engine which has a classic De Dion raise suspension design with hard pressed steel monocoque bodywork more than pressed steel frame framework. Unveiled to the mass media in 1963, production continued until 1970.The Iso Grifo A3L ended up being a monstrous idea for just a super coupé, the L coming via Lusso. The result of this brilliant Giugiaro and Bizzarrini doing the job together, it was based with a shortened Iso Rivolta GT framework and was debuted for the 1963 Turin show. The Grifo epitomised the actual 1960s Italian style which consists of handsome low and large handmade bodywork. It was the best production car tested by means of Autocar Magazine in 1966 which has a top speed of 160 mph (260 km/h). Later versions of the Grifo were powered by way of big block Chevrolet Corvette 435 bhp (324 kW; 441 PS) motor. These 90 handbuilt units are distinguishable from the raised "pagoda style" info bonnet. Some of these Iso Grifo 7 Litri models were rebuilt later with a whole lot larger engines.

The concept of Bizzarrini was to make use of the 3AL cars for levels of competition. The competition versions of the Grifo were named Iso Grifo A3C, C for Competizione as well as Corsa. A new lightweight riveted aluminium lightweight body was designed and built by Piero Drogo. It was an boldy designed machine, oriented to endurance backrounds. It uses normal ISO underpinnings even so the engine was moved further the government financial aid the chassis frame than the Grifo A3L, protruding well into your driver's cabin, fitted with hot cameras and fed by four big Weber carburettors, giving more than 400 bhp (298 kW; 406 PS).

All-around 29 A3C sport cars were built under the ISO name. Five of these twenty nine cars were bodied throughout plastic/fiberglass by Piero Drogo on Carrozzeria Sports Cars in Modena. A3Cs were widely raced. Some cars entered the 1964 and 1965 The Mans 24 hour, 1965 Nürburgring 1000 and also 1965 Sebring. It achieved a The Mans class win in both years along with a 9th overall in 1965 with no factory support. A3Cs were one on the fastest cars on LeMans' Mulsanne Right in both years.
