1973 Chevrolet Aerovette

(from General Motors Press Release)  Similar in design to the 1973 Corvette 4-Rotor Concept, the Aerovette had some subtle design differences, like a split grille compared to the one-piece grille on the 4-Rotor, and was also powered by a more conventional smallblock V8.  The Aerovette had gullwing doors and plastic front and rear bumpers that blended into the bodywork.
