General Motors Aero Concept Car

The Aero was a range of concept car studies created by General Motors as a testbed for future aerodynamic improvements to car bodies. The first model was the 1981 Aero X, a five-door hatchback. The 1982 Aero 2000 was a smaller two-door car with front and rear fender skirts, a kammback design and a smoothed underbelly, and it reached a drag coefficient of 0.23 although it had no engine and could not be driven. The Aero 2002, shown a year later, in 1983, and designed by Irv Rybicki, reached a drag coefficient of 0.14 and was to influence the 1984 Chevrolet Citation IV concept.
