30 concept cars that never hit the mainstream

Maybach Exelero

Made by Mercedez-Benz subsidiary Maybach-Motorenbau GmbH, this beautiful concept car was intended to reach 350 km/h (217 mph). It was seen in both the German TV show ‘Cobra 11’ and Jay-Z’s ‘Lost One’ music video, but only one Maybach Exelero was ever made.

Nissan IDx Nismo

First seen at the 2013 Tokyo Auto Show, the vehicle features side view mirrors that are actually cameras, which wholly impressed the public. Nissan appears to be using the IDx as a starting point for inspiration for other vehicles, but isn’t putting it into production, despite Jay Leno’s insistence on the matter.
