13. Plymouth XNR
The 1960 XNR concept car was an interesting piece of machinery since it was the idea of the Plymouth Corvette fighter. Also, it was the pet project of the famous Chrysler designer, Virgil Exner. If you compare the name of the XNR with Exner’s last name, you will get the idea.
Interestingly, the XNR was a rare car that utilized the idea of an asymmetric design with a heavy emphasis on the driver’s side of the vehicle. One most notable feature was the big fin behind the driver that Plymouth claimed improved the aerodynamics.
