For the first time, the XJ's body structure will be made from aluminium. This has resulted in a rare fact for a newly-launched car – despite being longer, wider, taller and 60% stiffer – it is actually lighter than the outgoing model.
Engines offered are 4.2-litre V8 (400bhp supercharged and 300bhp naturally aspirated), a 262bhp 3.5-litre V8 and a 240bhp 3.0-litre V6. All are fitted with a six-speed automatic gearbox and electronic parking brake.
Jaguar also claims interior space – the outgoing model's major flaw – is much improved in all directions, with comfort a top priority. Self-levelling air suspension and CATS (Computer Active Technology Suspension) is standard across the range and other electronic toys offered include dynamic stability control, Adaptive Cruise Control, and Adaptive Restraint Technology System.
Prices have not yet been announced, and the car will appear in the metal for the first time at the Paris Motor Show on September 26.
