The Iso Rivolta is a grand tourer introduced in 1962 by Italian automobile manufacturer Iso Automotoveicoli S.p.A. Company chairman Renzo Rivolta and his colleague, former Ferrari engineer Giotto Bizzarrini, saw it as a gran turismo in the original sense of the term, designed for long and memorable journeys.

For motor racing, an entirely different variant was made which bore a strong resemblance to the 1962 model Ferrari 250 GT SWB Breadvan and was homologated as a touring car.

For mechanical development of the car, the company founder and chairman entrusted Giotto Bizzarrini of Società Autostar.

Bizzarrini developed a pressed steel and welded panel chassis which was designed to flex fore and aft and proved to be rigid along with cost effective to manufacture.

The de Dion rear suspension and four wheel disc brakes would be shared with contemporary luxury offerings at the time.

The new car named the Rivolta IR 300 was presented to the public at the 1962 Torino Motor Show to a positive reception.
