In this document, Amory Lovins responds to questions about the Hypercar, RMI’s conceptual vehicle that combines ultralight and ultra-aerodynamic design, a hybrid-electric drivesystem, and other features to achieve very high fuel efficiency and very low emissions. The questions that he answers include: what is a Hypercar vehicle, how could Hypercar vehicles attain such dramatically improved fuel economy, would there be tradeoffs in performance or styling, why a hybrid-electric instead of a battery-electric vehicle, what fuels would Hypercar vehicles use, and are fuel cells being considered in Hypercar vehicles?
