The Jaguar XJ_e joins the family of efficient vehicles the automaker is rolling out, like the European-market XF 2.2D diesel engine car. The XJ_e is similar to the Range_e plug-in hybrid Range Rover Sport that was showcased earlier this year. The Range Rover Sport uses a 3.0-liter V6 along with battery power.
As for specifications, Jaguar says the XJ_e will go 25 miles on battery only and offers a combined fuel economy of 61.2 miles per gallon (on the European scale). It produces only 75 grams per kilometer of CO2 emissions – 70 percent less than the gasoline-only V8 version. The diesel XF gets 43.5 mpg on the European combined cycle. Some of the XJ_e's numbers hint at Jaguar's past, though, with a top speed of 150 mph and a 0-60 time of only 6.5 seconds.
