Jaguar-XE_Aluminium_-InfographicJaguar has revealed the new XE compact saloon will average more than 75mpg thanks to a lightweight structure made from 75% aluminium.

The lightweight new XE will thus better key rivals such as the BMW 3 Series EfficientDynamics, Audi A4 ultra and new Mercedes-Benz C-Class on fuel economy – and potentially be the first junior executive car to dip under the 100g/km CO2 barrier.

REVEALED: 7 cars the Jaguar XE has ALREADY beaten on mpg

To further worry them, Jaguar is also claiming world class driving dynamics to go with it: the XE “will be the true driver’s car in the segment”, it says.

The fifth-generation aluminium architecture’s “exceptional” torsional stiffness plays a key role here – but being able to claim such highs standards for the bonded and riveted platform hasn’t been the work of a monument for Jaguar…

Jaguar invents a new metal for the XE

Jaguar has actually invented a new type of aluminium alloy metal for the XE, called RC5754. This, says Jaguar, “uses highly recycled aluminium to dramatically reduce energy consumption and lifecycle CO2”.

We look forward to the technical presentations explaining the science behind that, particular as it’s part of Jaguars goal to uses 75% recycled aluminium in all it’s cars by 2020.

“The Jaguar XE body uses over 75% aluminium content, which far exceeds any other car in its class,” said Dr Mark White, Jaguar’s Chief Technical Specialist; Body Complete.

“This gives us a body structure with unrivalled low weight: it’s light but also immensely strong with extremely high levels of torsional stiffness.” Thus delivering those “unparalleled levels of ride quality, handling and steering”. Given such claims, anticipation for the new baby Jag build further.
