46. Saturn Ion
Saturn was a company born of optimism—the idea that a new American automotive manufacturer could break into the market with made-in-the-USA vehicles seemed like a pipe dream. But they did it, broke through, and for a while succeeded. With no thanks due to the Ion. The Saturn Ion was under-performing, with a smaller-than-average engine pushing what at the time was one of the longest four door sedans on the market. There was also the small issue of side impact—specifically the frame did very little to protect passengers from a good t-bone wreck. For these reasons and more, the Ion vanished in 2007.
