Jaguar XJ 2002–2007 car dimensions: 5090 mm long, 1859 mm wide and 1448 mm high. Unladen weight is 1,708 kg. Braked towing is 1,900 kg.
Dual-zone automatic climate control with air filtration is standard, with four-zone available as an option. Cruise control is standard, with adaptive cruise control on higher trims like the XJR. Rear parking sensors are standard. front sensors are optional. A 7-inch touchscreen comes with the optional DVD navigation system for audio and climate control. No factory reversing camera is offered.
The boot offers 470 litres of space with the seats up. As a sedan, the rear seats do not fold to expand cargo capacity.
Braked towing capacity is 1900 kg and unbraked is 750 kg. Payload is approximately 550 kg depending on model and options. Self-levelling air suspension is standard, with Computer Active Technology Suspension (CATS) on performance trims like the XJR for firmer control.
The cabin uses soft leather and wood veneers with twin-stitched seams. Front seats offer 12-way or 16-way power adjustment with memory on most grades. Dual-zone climate control is standard, with four-zone available. Acoustic laminated glass in front and side windows cuts noise. Air suspension delivers a smooth ride. Heated front and rear seats plus a heated steering wheel appear on higher grades or as options. A power moonroof is common.
Petrol V6 and V8 engines plus a twin-turbo diesel V6 available later in the run.
Standard safety kit includes dual front airbags, front side airbags, full-length curtain airbags, ABS with brake assist, dynamic stability control, traction control and seatbelt pretensioners.
Adaptive Restraint Technology System senses impact severity and occupant position to tailor airbag deployment.
Aluminium body structure is lighter yet stiffer than the prior steel generation.
Fuel options cover a 3.0-litre V6, 3.5-litre and 4.2-litre V8s in naturally aspirated form, a supercharged 4.2-litre V8, and a 2.7-litre twin-turbo diesel V6 introduced mid-cycle. All pair with a six-speed automatic gearbox. Real-world economy varies with engine and driving style but the aluminium construction helps keep weight down compared with earlier XJs.
The self-levelling air suspension and Computer Active Technology Suspension dampers need regular checks for leaks or compressor wear. The ZF automatic benefits from fluid and filter changes at higher mileages to extend life. Routine servicing follows standard luxury-car schedules focused on fluids, filters and electronics.
Safety equipment is comprehensive for the period. The Adaptive Restraint Technology System uses sensors to adjust airbag force. Stability and traction systems are standard across the range. The riveted and bonded aluminium monocoque improves crash energy management and torsional stiffness.
Keeping an XJ of this generation centres on air-suspension health, electronics reliability and corrosion checks on aluminium panels. Parts availability remains good through specialists. Regular use and documented maintenance keep the car pleasant for daily or long-distance driving.
