Supercar Collection

The word supercar later became to mean a "GT" or grand touring type of car. By the 1970s and 1980s the phrase was in regular use, if not precisely defined.
During the late 20th century, the term supercar was used to describe "a very expensive, fast or powerful car with a centrally located engine", and stated in more general terms: "it must be very fast, with sporting handling to match", "it should be sleek and eye-catching" and its price should be "one in a rarefied atmosphere of its own".
The supercar term has also been applied to technologically advanced vehicles using new fuel sources, powerplants, aerodynamics, and lightweight materials to develop an 80 mpg-US (2.9 L/100 km; 96 mpg-imp) family-sized sedan. "Supercar" was the unofficial description for the United States Department of Commerce R&D program, Partnership for a New Generation of Vehicles (PNGV). The program was established to support the domestic U.S. automakers (GM, Ford, and Chrysler) develop prototypes of a safe, clean, affordable car the size of the Ford Taurus, but delivering three times the fuel efficiency.
