Background
In 2003, Jaguar introduced the re-engineered and newly designed third generation of the XJ, designated internally as the X350.
It had an all-aluminium body and chassis, a 3.0-litre V6 engine, and new 3.5 and 4.2-litre V8 engines. It was the first Jaguar XJ to be completely designed under Ford ownership (which soon became Tata ownership) and introduced an array of new electronics and computer-controlled systems.
A new, lighter, six-speed automatic gearbox was fitted, offering improved economy and a wider spectrum of gear ratios.
The X350's aluminum bodyshell used an aerospace construction method; a hybrid of adhesive bonding and rivet joinery known as rivet-bonding or riv-bonding.
An industry first in volume automotive production, this technique resulted in a monocoque chassis that was both 40% lighter and 50% stiffer than that of the outgoing model.
The styling of its aluminium body panels was an evolution of the classic XJ look and marked the final (and much missed) expression of that signature aesthetic.
Air suspension was fitted at the front and rear, providing adaptive damping as well as rear self-leveling, with computer-controlled ride height and suspension modes. Dynamic stability control and traction control were standard.
The Grace, Space and Pace bloodline linking (almost) every offering from Castle Bromwich for the past 50 years was still clearly running through the veins of the X350.
