The current XJ is definitely showing its age if you line it up next to the S-Class, 7 Series, LS, and the A8, but the good news is Jaguar is hard at work preparing an all-new model. While Mercedes, BMW, and Lexus are selling hybrid versions of their flagship models (Audi will be doing the same with the A8 E-Tron), Jaguar will forgo the combustion engine altogether.

Indeed, the next installment of the large luxury sedan is rumored to go fully electric to take on the Tesla Model S and to serve as a technological tour de force for Jaguar Land Rover. Rumor has it design work has been completed and the zero-emissions is being developed alongside a road-oriented Range Rover model known internally at JLR as the "Road Rover."

Aside from going full EV, the next-gen Jaguar range topper will go through other changes as the conventional four-door sedan body style will be eschewed to make way for a sleeker five-door layout. This modification is expected to also pay dividends in terms of practicality as it will be much easier to maneuver cargo in and out of the trunk.
