摘要
轻量化对于汽车业的发展具有重要意义。汽车的油耗主要取决于发动机的排量和汽车的总质量，在保持汽车整体品质、性能和造价不变甚至优化的前提下，通过降低汽车自身重量来提高输出功率、降低噪声、提升操纵性、可靠性，提高车速、降低油耗、减少废气排放量、提升安全性是汽车轻量化的最终目标。
The fuel consumption of a vehicle is mainly depends upon engine displacement and overall weight.With the conditions of maintaining or even optimizing overall quality,performance and cost,the final objective for automotive weight lightening is to improve output power,maneuverability,reliability and speed,as well as reducing noise and exhaust emission.
