Supercar is a term generally used for high-end sports cars, whose performance is superior to that of its contemporaries. It has been defined specifically as "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",but the correct usage of the term is both subjective and disputed, especially amongst enthusiasts. The use of the term can be dependent on the era; a vehicle that may have been considered a supercar in one decade may not be considered the same in another. The term supercar may refer to factory-built, street-legal sports cars.Some vehicles referred to as supercars include features required for race cars such as roll cages.
