Ultralight Vehicles: Non-Linear Correlations Between Weight and Safety

Journal or Magazine Article, 2008
Development of dramatically lightweight and fuel-efficient vehicles has been slowed by perceptions that lighter vehicles are less safe. This conference paper describes RMI's virtually modeled ultralight concept vehicle that met NHTSA safety requirements, and shows how lightweighting the fleet can accelerate progress towards “Triple Safety”—protection from climate change, drivers themselves, and other road users.


Triple Safety: Lightweighting Automobiles to Improve Occupant, Highway, and Global Safety

Journal or Magazine Article, 2008

Automobilesʼ negative impact on human health and welfare includes traffic-related deaths and injuries as well as the deaths and injuries caused by automobilesʼ contribution to climate change and other global environmental degradation. This paper explores solutions that both enhance vehicle performance and reduce environmental impacts, and focuses on demonstrating the ability of lightweight vehicles to provide such a solution. Some controversy exists around the question of whether lighter and more fuel-efficient vehicles can be as safe as traditional vehicles. Recent research reviewed in this paper indicates that several solutions exist that can both improve efficiency and thereby global safety, and maintain (or even improve) highway safety.

Reforming the Automobile Fuel Economy Standards Program: Letter to the NHTSA

Letter, 2004

In this 2004 letter to the NHTSA, Amory Lovins challenges the agency's proposed policy about the Automobile Fuel Economy Standards Program. He argues that NHTSA's policy should be performance-based, not prescriptive; that the standards should be neutral as to vehicle mass, or favor the down-sized vehicles; if fuel-economy choices are desired to be decoupled from vehicle-size-class choices, then this is done by normalizing to size; and the standards should be technology-neutral or technology-forcing.


Hypercars: FAQ

Report or White Paper, 1997
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.
