Jaguar’s all-new XJ luxury saloon is reportedly due sometime in 2010, but in the interim, Jaguar has introduced a few changes to the 2009 XJ to help move a few more XJs out of showrooms before the newcomer arrives.

Externally the changes are subtle. A new front-end design, fender vents, rear spoiler and rear bumper round out the main bodywork changes, however the classic lines of the low-slung XJ have thankfully remained intact.

Inside there’s more rear leg and foot room thanks to new front seat backs, while the front seats themselves are now heated as standard with seat cooling optional. Sat-nav, parking sensors, Bi-xenon headlights and extra brightwork are now standard across the range too.

The 2010 Jaguar XJ range offers just two engines, each of which is virtually the polar opposite of the other. A 2.7-litre twin-turbo diesel V6 powers the XJ Executive and XJ Sovereign, pumping out 152kW, while Jaguar’s evergreen 298kW 4.2-litre supercharged V8 rumbles away under the nose of the XJ Super V8. The diesel drinks just 8.07 litres of fuel per 100km, while the V8… well, if you’re buying the V8 you’re probably not fussed.

UK pricing is currently set at £44,599 ($101,490 AUS) for the XJ Executive, £50,472 ($114,878) for the Sovereign and £57,760 ($131,464 AUD)for the Super V8. Australian pricing should be released shortly.
