For the past year, Jaguar, Lotus, Caparo Vehicle technologies and the MIRA proving ground have been working on a UK government-funded project dubbed Limo-Green. The goal of the project was to develop and build a series hybrid luxury sedan. Earlier this week, Jaguar showed off the car for the first time. Most of the powertrain development work was done using a last generation XJ, but recently all the hardware was moved into the just launched 2010 Jaguar XJ.

Like the Chevy Volt and Fisker Karma, the Limo-Green uses an electric motor for propulsion, in this case a 145 kW, 295 lb-ft unit. A lithium battery pack moves the car for 30 miles on a charge and then the Lotus-developed 1.2-liter range extender takes over for the remainder of the 600-mile range. We've contacted Jaguar for more information, but we're still waiting to hear back. In the meantime, AutoCar is reporting that the big Jag gets 47 mpg (US) on the EU combined cycle with CO2 emissions under 120 g/km.
