When you think of three-wheelers, you'll like think of three different manufacturers. There's the OG, Morgan, the odd-ball that is Polaris, and the newcomer in the space of Vanderhall. And even in this niche-upon-niche segment, each, however, takes very different approaches to the space.
Morgan maintains the bathub-esque shape and motorcycle powerplant. Polaris went more comfy-cozy, and built what's basically a sports car with three wheels. And Vanderhall? It's front-wheel-drive for some unknown reason. And while more traditional motorcycle-style trikes exist from Harley and Indian, that's about it on the three-wheeler front.
But there was almost a fourth manufacturer. One with the might of Germany's car brand behind it. Have you ever heard of the Volkswagen GX3 concept?
