What is "hypercar"

The Hypercar is a design concept car developed by energy analyst Amory Lovins at the Rocky Mountain Institute. This vehicle would have ultra-light construction with an aerodynamic body using advanced composite materials, low- drag design, and hybrid drive. Designers of the Hypercar claim that it would achieve a three- to five-fold improvement in fuel economy, equal or better performance, safety, amenity, and affordability, compared with today's cars.
