Hybrid systems developed by the Jaguar Land Rover engineering group, already scheduled to make their way into upcoming Range Rovers, will also be introduced into Jaguar's XJ and XF sedans.  They are expected to launch as early as 2013, according to Inside Line.

The green Jags are expected to have performance targets similar to those of the range_e based hybrid Land Rover.  A diesel-electric version will make use of the existing 3.0L V6, and a gasoline-electric version is under development.

Both versions will eventually be incorporated across the range of Jaguar and Land Rover models, with a plug-in option appearing closer to 2015.  This activity reflects an industry trend among luxury auto makers adding hybrid options to make improvements in fuel economy.  Expect to see a lot more of this in the next 5 years, as global regulations continue to become more demanding.
