• 1959 Cadillac Cyclone
  Also on display are the futuristic 1951 General Motors Le Sabre XP-8 that renowned designer Harley Earl used as his personal car, the 1955 Streamline X that Chrysler developed jointly with Carrozzeria Ghia, the 1959 Cadillac Cyclone XP-74 with its Jetsons-like bubble canopy roof and the fiberglass-bodied 1956 Buick Centurion XP-301, a family sedan whose steering column ran down the center of the passenger compartment in order to clear up more leg room for the driver.

• Ferrari 365P
  Two Italian cars are on display, including the three-seater Ferrari 365P Berlinetta Speciale tre posti that was unveiled at the 1966 Paris Motor Show. Developed by Pininfarina to show Enzo Ferrari that it was possible to build a safe mid-engined sports car, the 365 stood out with a steering wheel that was mounted front and center, a setup used again much later by Gordon Murray when he designed the McLaren F1. The Bertone-penned 1970 Lancia Stratos HF Zero concept is right around the corner from the 365P.

BMW GINA
Last but not least, the two newest cars on display are the controversially styled BMW GINA (Geometry and functions In ‘N’ Adaptations), a roadster whose body is entirely upholstered with a special type of Spandex, and the Porsche 918 Spyder concept that was presented to the public at the 2010 edition of the Geneva Motor Show. The 918 Spyder is nearly identical to the limited-edition – and now sold-out – production model that was introduced at the 2013 Frankfurt show.
