As automakers expand their menu of materials new concerns arise, from joining techniques to reconsidering body structure architecture
It is common sense—a vehicle that weighs less requires less fuel to move it. A number of studies show that reducing the mass of a vehicle by 10% results in anywhere from 4.5 to 6% better fuel economy—well worth the effort. The dilemma for automakers is that mass reduction needs to happen without compromising safety, NVH, styling, or size. Luxury sedans and half-ton pickup trucks need to remain large, safe, and quiet even if they weigh less. “To accomplish this challenging lightweighting goal, we need to leverage the entire palette of materials that we have and is available to us from the supply base,” said Dr. Hesham Ezzat, Technical Fellow, Body for General Motors (Detroit, MI).
