With an eye towards sustainability, Jaguar is making a distinct effort to refresh its old English image with the introduction of the 2011 XJ, the luxury carmaker’s flagship model. Constructed from 50 percent recycled aluminum, the XJ is something of a lightweight compared to previous iterations. Its riveted and glue-bonded unibody—derived from aerospace technology—makes for a lighter weight skin than steel without compromising safety, increasing the vehicle’s efficiency tenfold. The use of aluminum saves six tons of carbon per vehicle over its lifetime.
