PNGV Lightweight Body Structure

US automakers and the Department of Energy formed the Partnership for a New Generation of Vehicles (PNGV) to develop new technologies increasing passenger car fuel economy. Using a combination of carbon fibre and Kevlar composite materials and aluminum main crash rails, a mass reduction of 67% was achieved over a conventional steel unibody. Stiffness and natural frequencies were increased, and testing correlated well with analytical models.
