Jaguar XJ X350, X356, and X358 (2003–2009)

In 2003, Jaguar introduced the re-engineered and newly designed third generation of the XJ, continuing with the XJ8 model designation. Designated internally as the X350, it featured an all-aluminium body and chassis, a new V8 engine, as well as greater interior and luggage spaces. It was the first Jaguar XJ to be completely designed under Ford ownership and used electronics and computer-controlled systems sourced through existing partner suppliers or directly produced by Ford.[citation needed] Just under 85,000 were manufactured over its seven year production run.


The V8 engine was offered in larger 3.5 and 4.2-litre displacements as well in a supercharged variation. A 3.0-litre V6 engine was also offered; neither the V6 petrol nor diesel engines were available in US markets. A new six-speed automatic gearbox was fitted which was lighter and offered better economy with lock-up on all gears and a larger spread of ratios.


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 mode. Dynamic stability control as well as traction control were standard. Radar based adaptive cruise control was offered. Two-zone climate control was also standard, with four-zone available on long-wheelbase models. An optional touch screen interface controlled default settings, satellite navigation, the Alpine audio system, and bluetooth telephone. Jaguar Voice offered voice control of many functions.

A Jaguar emblem within the grille replaced the previous bonnet-mounted bonnet mascot. The front lights were revised and door mirrors incorporated side repeaters. The side sills, rear bumper, and taillights were revised. The interior featured redesigned front seats.
