Spy shots show XF doing some winter testing in Scandinavia and sporting a modest styling revision.

Here are the latest spy shots of the upcoming facelifted 2012 Jaguar XF.

Spied for the first time winter testing in Scandinavia, the modest update that the XF will get is not easily being given away here. In fact, the camouflage maybe tells us there will be substantial stylistic revisions to both the front and rear ends of the car.

The design changes to the front fascia appear to include a larger grille and new headlights. At the back is a new taillight cluster and a revised bumper. But since Jag is still covering body panels such as the side wings (front and back) as well as the bonnet and trunk, there may be even more changes to the XF's styling coming than we've been able to spot.

No new power plants are expected under the hood but a future Jaguar XF model range may also sport a hybrid variant, as Jaguar showed such a prototype last year.
