HybridHyperCar

What is a Hypercar® Vehicle?
A Hypercar® vehicle is designed to capture the synergies of: ultralight construction; low-drag design; hybrid-electric drive; and, efficient accessories to
achieve 3 to 5-fold improvement in fuel economy, equal or better performance, safety, amenity and affordability, compared to today's vehicles.
Hypercar ConceptRocky Mountain Institute's research has shown that the best (possibly, the only) way to achieve this is by building an aerodynamic
vehicle body using advanced composite materials and powering it with an efficient hybrid-electric drive-train. Initially, the hybrid-electric drivetrain in
Hypercar® vehicles will probably use a specialized version of the internal combustion engine commonly used in today's cars. [rmi.org]
