Prototype composite Jaguar XF door module, press moulded from woven flax reinforced PP, produced by Composites Evolution

The metal chassis for the Jaguar XE, launched 2014, is made up of 75% aluminium and 25% steel for an exceptionally light and strong monocoque. It utilises riveted and bonded Novelis RC 5754, a strain hardening AlMgMn aluminium alloy. Developed especially for automotive bodies, it is soft and formable, making it economic for production. It is available with a high level of recycled content, using scrap from manufacture. Lightweight aluminium chassis utilise a range of other alloys, depending on the requirements of the parts, including 3000 series, 5000 series, 6000 series and 7000 series for the stiffest parts.
