Tata Motors' Jaguar is continuing its drip-feed of XE saloon details with the latest being it will be the first car to use of a new grade of high strength aluminium called RC5754 developed specifically for the model.

The alloy uses a high level of recycled material and, the automaker said, "makes a significant contribution to its goal of using 75% recycled material by 2020".

The XE will be the only car in the class to use an aluminium-intensive monocoque, with the metal accounting for 75% of the structure.

The automaker has alloy form. Its XJ, XK and F-Type all have exceptionally stiff bonded and riveted aluminium structures.

The weight reduction realised ensures that the XE is the most fuel-efficient Jaguar yet with fuel consumption and CO2 emissions on the NEDC combined cycle of over 75mpg and less than 100g/km respectively.

"The Jaguar XE body uses over 75% aluminium content, which far exceeds any other car in its class. This gives us a body structure with unrivalled low weight: it’s light but also immensely strong with extremely high levels of torsional stiffness. We’ve made sure our aluminium-intensive body structure exceeds all global safety standards without compromising on vehicle design or refinement," said body specialist Mark White.

The XE will be the first Jaguar to be manufactured in a new purpose-built production facility at the company’s Solihull plant.
