CADILLAC INTRODUCES LIGHTWEIGHT LUXURY

摘要

Weight is a problem when it comes to fuel economy. The heavier something is, the more energy you burn moving it down the road. The engineers at Cadillac tackled this problem head-on with the new CT6. Rather than relying on expensive carbon fiber or heavy steel, they created a lightweight chassis from a new composite. The result marries 11 materials including high-strength steel and lightweight aluminum, shaving 198 pounds off the traditional chassis.
