With the BMW 7-Series and Mercedes-Benz S-Class getting mixed reviews on their quirky styling, the Jaguar XJ sedan remains one of the most elegant luxury sedans on the market. Not to rest on its laurels, though, Jaguar is apparently preparing a mild face-lift of its range-topping sedan.

The subtle update appears to be purely cosmetic. From the spy shots we can see that most of the bodywork will carry over unchanged, with just a few tweaks at the front, back and on the side of the front fenders. Ironically, with the body-cladding, the XJ looks more like a BMW up front, where the revised version will get what appears to be a new airdam and possibly an evolved grille and/or headlights. Around back the big cat is treated to a new rear bumper. And the test mule appears to be wearing side-vents like those on the top-of-the-line Portfolio trim level, which could indicate that the air vents will trickle down through the full model range.

Jaguar's still got a long way to go before it can pose a serious challenge to the big German marques, but that won't stop it from trying.
