19 Cars Once Known As "World's Fastest Production Car"

13. Iso Grifo GL365 161mph/1963

Now this is a car that you may not know about. I’ll be honest, I’ve been obsessed with cars my whole life and its a new one for me also. Its called the Iso Grifo and its designed and built in Italy, but under the hood was a good old American V8. The first models came with a Chevy 327 cubic inch motor producing an estimated 355hp, but throughout the 10 year production there where quite a few other choices.
