The Hypercar® is a conceptual vehicle developed by the Rocky Mountain Institute (RMI) that integrates ultralightweight construction, ultra-aerodynamic design, and hybrid-electric propulsion to achieve extreme fuel efficiency without sacrificing safety or performance.

This research paper describes the 'hypercar' concept—an ultralight, hybrid-electric vehicle designed using a system-level optimization approach to minimize lifecycle environmental impacts without sacrificing consumer-valued features like performance and price.

This research paper by the Rocky Mountain Institute proposes a radical redesign of the light-vehicle industry, moving away from incremental improvements of steel cars toward 'supercars': ultralight, hybrid-electric vehicles constructed from net-shape polymer composites. The authors argue that integrating advanced materials, switched reluctance motors, and hybrid drives could increase fuel efficiency by up to ten times compared to 1990 US production cars, while simultaneously improving safety, reducing production costs, and transforming the industrial structure of automotive manufacturing and sales.

This fact sheet from the Environmental and Energy Study Institute outlines the technology, environmental benefits, and economic considerations of hybrid-electric buses compared to conventional diesel and compressed natural gas (CNG) buses in North America.

This research paper by Rocky Mountain Institute (RMI) argues that the automotive industry's failure to adopt advanced composite materials in the body-in-white (BIW) is due to a reliance on incremental, component-based substitution. The authors propose a "leapfrog" strategy: a whole-system redesign using an all-advanced-composite monocoque BIW integrated with a hybrid-electric "hypercar" concept. This approach aims to overcome cost, manufacturing, and cultural barriers by maximizing mass reduction and simplifying assembly.

This research paper by Amory B. Lovins of the Rocky Mountain Institute (RMI) proposes the 'hypercar'—a vehicle combining ultralight mass, ultralow aerodynamic drag, and hybrid-electric drive to achieve fuel economies 4–10 times higher than conventional cars. The author argues that by using advanced composites and recursive design, manufacturers can reduce costs and mass simultaneously, bypassing the incremental improvements of the traditional automotive industry to create a more efficient, safer, and cheaper vehicle.
