Running a car company has got to be a fiendishly complicated thing to do. Not only do you have to design, launch, market, and sell cars, you also have to meet government regulations for any number of countries, keep your customers happy, and appease shareholders. This complexity means that sometimes the machinery of business breaks down and the ball gets dropped somewhere. Most of the time that’s not big enough for people outside the company to notice, but other times it’s enough to cause massive trouble. This list is for the latter.

Fails happen even with the best of intentions, as in the cases of Bollinger, Dyson, Alfa Romeo, and Fisker, or slightly less than the best of intentions, as with Dieselgate and Nikola. Then there are those with weird intentions, like the Tesla Model S Plaid’s yoke or the Mercedes-AMG SL43. There are supercars that tried to be too super, like the SSC Tuatara and the Hennessey Venom F5, and also the new Tesla Roadster, which doesn’t even exist yet.

There are, in other words, a lot of ways to fail in the car world, and probably more ways to fail than there are to succeed. History is littered with long-gone automakers, car startups that never got off the ground, and ideas that were best left on the drawing board or clay model. Originally, they were full of hope.
