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.
