In November of last year, our spy photographers managed to catch the revised Jaguar XJ prototype->ke146 testing in the wild. Now, the car was caught testing again, but this time out in the cold.

As you can see, the prototype is camouflaged only on the front and rear, meaning that these are the areas that will receive the updates. We expect to see new front and rear bumpers, new headlights and taillights, and likely a new grille. Jaguar->ke39 will also offer an updated interior, some new technology and some new exterior colors.

There are no details on the engine lineup just yet, but we expect to see the same engines found in the current model. We do expect to see improvements in the output and fuel economy of the entire lineup.

We expect the revised Jaguar XJ to be revealed by the end of 2014.
