Jaguar revealed the first teasers and some info today of the 2010 XJ at the Shangai Auto Show. The data from Jag was stuff the we pretty much already knew - the new 5.0-liter V8, including the 510 hp supercharged version, will be available as well as a carryover of the diesel V6 (but not likely in the U.S.) It will have a light aluminum body and even a panoramic roof.

But the big news are the new threads. The current XJ has been an evolution of a 40+ year-old design, and Jaguar has made no secret of its intentions to change the style for the 2010 car. Just look at the front end:

We shouldn't have to wait too long for more information to start hitting the streets. Jaguar plans to have the official reveal of the next XJ in London on July 9th, and the cars should be on the streets by early 2010.

Press release after the jump.
