Next-generation XJ will feature a 510 bhp supercharged V8 with 625 Nm of torque. The XJ will also offer all of Jaguar's Gen III, ultra-efficient engines, including the new 3.0 liter turbo-diesel V6 with a mileage rating of 40 mpg (UK) or 7 liters/100km.

Jaguar has released this teaser video for the next-generation XJ and announced some details on its upcoming release.

You don't get to see much of the car in the video, as it is show only from a top view in an Hitchcock-esque overhead shot, but that is the point of a teaser, though, isn't it?

At the Auto Shanghai 2009, Mike O'Driscoll, managing director of Jaguar Cars, announced that the XJ will be officially unveiled on July 9th and he also provided some tidbits of info on the new model.

The XJ will be the first car constructed using Jaguar's aerospace-derived technology and will feature an aluminum body architecture. O'Driscoll announced the model will come in both a standard and long-wheelbase version too. The XJ will also offer every Gen III engine available in the Jaguar range, including the new V6 diesel and 510 bhp supercharged V8 engines, which Jaguar promises are more efficient than previous iterations.

Already known was that the new XJ would be fitted with that 510 bhp 5.0 liter supercharged V8 with 625 Nm of churning and cranking torque, the same engine recently introduced in the Land Rover Range Rover. The V6 diesel will also be a winner in diesel-heavy markets. The 3.0 liter turbo-diesel engine features 271 bhp and 600 Nm of torque, almost as much as the supercharged V8, and a solid 40 mpg (UK) mileage rating (7 liters per 100 km).

Jaguar will begin taking orders for the XJ after its unveiling in July for delivery in early 2010. The XJ goes on sale in dealer showrooms at the end of 2009.
