"The GM Aero 2000, one of the most aerodynamic automobiles ever developed, was unveiled in 1982 at the Epcot Center World of Design display. The experimental four-seater featured sliding doors, front wheel skirts top-hinged for access to wheels and tires, and a speed-regulated rear foil to reduce fuel-costly air turbulence. Many of the design concepts are evident in GM's electric car, EV1."
The hub caps look like pie plates to me...top hinged it is...
It has a 3 cylinder TDI engine...
The difference between style and aerodynamics is aerodynamics never go out of style, cool a pop out boat tail...
