13. Iso Grifo 90
The legendary Iso Grifo from the ‘60s and early ‘70s left an everlasting mark on the industry. So, in 1990, Pietro Rivolta, the son of the founder, presented the Grifo 90 concept. They built it on a Corvette C4 chassis with a special new body designed by the renowned stylist, Marcello Gandini. Unfortunately, financial problems forced the cancelation of the project, so the Grifo 90 was forgotten.
This is a big shame since the Grifo 90 used a Corvette C4 ZR1 running gear and chassis. And that meant it had 405 horses under the hood to deliver some brutal performance numbers. The Iso Grifo body was even a bit lighter than the Corvette, which improved the car’s top speed.
