Plymouth XNR
The 1960 XNR concept car was a fascinating piece of machinery. Not only was it the idea of Plymouth’s Corvette fighter but it was also a pet project of Chrysler’s famous designer, Virgil Exner. If you compare the name of the car (XNR) and the designer’s last name (Exner), you’ll get the idea (via Petersen).
On the other hand, XNR was one of the rare cars that utilized the idea of asymmetric design with heavy emphasis on the vehicle’s driver’s side. The most notable feature was the big fin behind the driver, which Plymouth claimed helped aerodynamics.
