Ever wonder what the fastest cars of their times were? This article is great for answering that question. Even a quick flip through shows GM staying right up there with Porsche and Ferrari in many years. The Shelby Fords are right up there to in some years. There are a lot of Corvettes naturally, but some others you may not expect to be the fastest cars of their years. The Buick GNX, the 1958 Chevrolet 315 Delray at 7.2 seconds in the 0 to 60, and the 1966 Plymouth Satellite 426 Hemi at 5.3 seconds tying with a Porsche 904 at 5.3 seconds are some of the unsung heroes.
