The Jaguar design team has made the new XJ longer, taller and wider than its predecessor, and lighter as well.

The new XJ body is manufactured almost entirely from aluminium, using the same lightweight but ultra-strong techniques featured in aircraft. The bodyshell (known as the body-in-white or BIW) is some 40 per cent lighter than that of an equivalent steel body.

It is also 60 per cent stiffer than its predecessor, which Jaguar says helps the new XJ achieve excellent dynamic performance, safety, refinement and durability.

The doors are noticeably deeper and the waistline higher than in the previous generation and the new car has a slightly more 'cab-forward' approach, with the four wheels closer to the corners. The front overhang is much reduced and the windscreen rake is faster (less steep), but the resulting smaller bonnet retains the characteristic sculpted XJ shape.

The headlights are now oval in shape and arranged in a quad design, positioned on either side of a new grille of intersecting vertical and horizontal bars that takes its inspiration from the original 1968 XJ6 (XJR models have a different grille), according to the company.

Inside, the XJ was designed so the driver and passenger would "always get out of a Jaguar feeling better than when they entered," with contemporary luxury being the dominant theme. The new interior offers more headroom, legroom, and shoulder room to its passengers, as well as an array of accessories and features.

Passengers can customize their seating comfort with a 16-way adjustable seat with cushion-length adjustment and 4-way lumbar support. In the rear, buyers not satisfied with a fixed seat can opt for a powered bench with electrically adjustable lumbar support, backrest and head restraints (model and market dependent). Adjustable pedals are also available to complement the electrically adjustable steering column.

The XJ comes with a multi-media entertainment system that allows up to three different audio, video or games systems to be played at once, with the help of separate viewing screens and headphones. Other features include JaguarVoice (voice-activated control of systems including audio controls, telephone, climate control and navigation) and four-zone climate control with dedicated face vents and foot outlet grilles.

The new XJ will be available with a choice of four engines: A 4.2-litre supercharged V8 delivering a massive 400 hp powers the XJR model, while a naturally aspirated 4.2-litre engine developing 300 hp sits one step below. A new 3.5-litre V8 delivers 262 hp, with a 240-hp 3.0-litre V6 engine powering the XJ6.

All four engines are coupled with a six-speed automatic that Jaguar first introduced earlier this year in the revised S-TYPE.

Self-levelling air suspension is fitted as standard across the range. Air suspension ensures that full suspension travel is always available by increasing spring stiffness relative to payload, Jaguar says. The air system ensures ride height remains constant regardless of load conditions - an important factor because in the lightweight XJ, vehicle occupants represent a relatively higher proportion of gross vehicle weight. The air suspension automatically lowers the ride height at speed to improve stability and increase aerodynamic efficiency.

The new XJ also carries an enhanced version of Jaguar's CATS Computer Active Technology Suspension which helps optimise ride and handling under all conditions, electronically maximising dynamic performance and driver control. A completely automatic system governed by the same Electronic Control Unit that controls the air suspension, CATS requires no intervention from the driver, the damper settings being adjusted in milliseconds to suit driving conditions.

An electronic park brake helps free up space between the front seats, and is automatically applied once the key is removed from the ignition. The braking system, which is equipped with a standard four-channel anti-lock function, incorporates Emergency Brake Assist, which senses if a driver is not applying maximum braking in an emergency and intervenes to deliver the necessary additional force.

The XJ also comes with Dynamic Stability Control, a safety-oriented system that intervenes if it detects the vehicle is at the limit of its grip capabilities and applies braking force to bring the situation back under control. For more relaxed situations, the driver can choose to employ the Adaptive Cruise Control.

Pricing for the 2004 Jaguar XJ starts at $87,500 for the XJ8 and $105,000 for the XJR.
