Iso sports cars were the brainchild of Italian industrialist Renzo Rivolta. After successful ventures in other forms of vehicle production, Rivolta decided to produce a sports car with a powerful U.S.-built engine and a homegrown Italian body. The first car was the elegant Iso Rivolta in 1962 featuring a Chevrolet 350 V8.
However, the best Iso model was the sublime Grifo. It was an elegant, dramatically styled coupe they presented in 1964. Immediately, it became one of the most advanced, fastest and desirable sports coupes on the market. And that was a big deal since the mid-60s in Italy meant there was serious competition from heavy hitters like Ferrari, Maserati and Lamborghini.
But the Iso Grifo was more beautiful and faster than anything else. The base engine was a 350 V8 they tuned to produce more than 350 HP. After a couple of years, Iso switched to the 427 V8 with 400 HP and even produced one series of the Grifo with a Ford V8 engine. Unfortunately, in the mid-70s, the company went out of business.
