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.
Fitted with a multi-link, four-wheel computer-controlled adaptive air suspension, the X350 handled as well as it rode. So well in fact that Jaguar developed an XJR version – and while the previous version had featured a 326bhp supercharged straight-six, the new model had a 395bhp supercharged V8 under the bonnet.
Thus empowered, the X350 XJR’s blistering performance soon became the stuff of legend and a best-kept-secret nod and wink between those in the know.
Well, the secret is well and truly out today and these hugely capable cars are, quite rightly, much sought-after by those who remain firmly in the market for Grace, Space and (jaw-dropping) Pace.
