After WWII, the demand for new means of transport increased. Being a field that had attracted Renzo since his youth, he eagerly dedicated himself to building scooters, motorcycles, small vehicles, and then the famous Isetta Bubble Car. It was in this evolutionary period that the company name was shortened to simply 'Iso'.
In 1962, the time was ripe for a sports car venture, and so the first Gran Turismo, called the IsoRivolta GT, was completed. It was based on a visionary concept for that time: a large displacement engine, powerful and reliable, combined with an exceptionally performing chassis resulted in a car that was pleasant and safe to drive, especially at high speeds.
Following that theme, in the mid '60s, Piero Rivolta - Renzo’s son - continued to produce exciting new models and decided to change the name of the company to IsoRivolta, as a tribute to the first GT. In 1971, a new, more modern factory was built in the nearby town of Varedo.
By that time, IsoRivolta had become internationally famous among the most sophisticated car enthusiasts for their innovative approach in marrying Italian design with American powertrains, thus producing exceptional and reliable performance automobiles.
IsoRivolta sports and racing models participated in some of the world's greatest motoring competitions, such as the 12 Hours of Sebring, the 1000 km of the Nürburgring, the 24 Hours of Le Mans and two seasons in the Formula 1 Championship under the Marlboro sponsorship.
