He also details the Clean Car Initiative of 1994 and discusses the design and…

Vehicle Design Strategies to Meet and Exceed PNGV Goals

A host of important and interactive factors contribute to the successful design of any production vehicle. However, the combination of hybrid-electric drive and low-drag platform design, with emphasis on vehicle mass and drag coefficient reductions, appears prerequisite to the simultaneous optimization of efficiency, emissions, performance, and cost. This paper examines…

Costing the Ultralite in Volume Production: Can Advanced Composite Bodies-in-White Be Affordable?

Advances in materials engineering, powerplant technology, systems integration, and fabrication processes now enable the automotive industry to design and prototype vehicles with improved performance and far better efficiency than current production platforms. The hypercar advanced vehicle concept embodies this technological potential. However, for hypercars to benefit society significantly, they must…

Reinventing the Wheels

This article describes a strategy for developing an ultralight car such as RMI’s Hypercar. The article describes the potential public benefits of Hypercars in terms of oil displacement, energy security, international stability, forgone military costs, balance of trade, climatic protection, clean air, health and safety, noise reduction, and quality of…
