Jaguar has found its new styling directing with the XF. That’s why when the 2010 XJ breaks cover, don’t be surprised if the big brother is taking some major cues from the smaller sibling. Taking that idea to the extreme is the rendered photo above. Starting with an XF, this shot uses the coupe-within-a-sedan look and gives it a less sloping C-pillar to give the car better rear headroom. The whole body is a little more sedate than the XF, possibly suggesting the bigger cat wants to be a little subtler.

When the official specs are announced, we expect engine choices to be variations of the new 5.0-liter V8 that will range from 400 to 500 hp. There is also expected to be a diesel version that will not make it to the U.S. Just like the XF, where it used its predecessor car as a chassis base, the 2010 XJ will likely carryover the current car’s aluminum chassis.

Now all we can do is hope that Jaguar can stay on task with this car. The new XJ is currently scheduled for 2010. But as projects are being canceled from major manufacturers because of slowing sales, small luxury carmakers like Jaguar have seen their showroom numbers trickle to almost nothing. Although Jaguar still has the large corporate parent Tata behind it, its plant is currently at idle. The unions in England are asking the government for aid to safeguard manufacturing jobs at the car factories. All of this does not add up to a large investment in a new luxury car anytime soon.
