10 Incredible Vintage Concept Cars
8. Cadillac XP-840 Eldorado Fastback

The first car on this list that’s absolutely barking mad, the XP-840 Eldorado Fastback started out as a bit of fun, just scale models and one clay. The engine under the hood was to be a V16, and thus, the hood needed to be…substantial, shall we say. Despite largely being just for creative purposes, the car ended up as one of GM’s Xperimental Projects, and ended up being shown in the GM Design forecourt. The engine isn’t the only thing that’s crazy about this car. There’s no rear windshield or rearview, for instance. Instead, there was a port built into the back of the car for a camera. In 1965!

An undercut nose leads up to a starkly split windshield, which lacks any A-pillars. The hood spills out into cuffs that are entirely pointless, but look good. It’s important to stress just how thoroughly impractical this car really is. Far too big, the camera idea was ridiculous, and a V16 would have been a bit much. That being said, we still love it. Imagine if this had been seen through, just how powerful and outright bonkers it would have been.
