Jaguar has seen fit to contract its small engine work out to Lotus, which makes sense given the two British company’s differing product specialties. Lotus has reportedly delivered a 1.2-liter three-cylinder engine that generates 35kW of power, which is carried – with a little help from a UK government grant or two – inside a new 2011 XJ sedan with a lithium ion battery pack.

Motive force comes courtesy of what Autocar believes is a 145kW (194 horsepower) electric motor with 295 pound-feet of torque. Performance specifications sound pretty good – though not quite as impressive as we might have imagined – assuming all of this is accurate, with a range of 600 miles, combined fuel economy of 47 miles per gallon (57 mpg UK) and carbon emissions of under 120 g/km. Top speed would reportedly come in at 112 miles per hour.

An unnamed source at Jaguar tells Autocar that the electric XJ handles quite well “because of the bulk that’s removed from car when you strip out the conventional drivetrain.” Future Range Rover models are also rumored to get a similar drivetrain.

Jaguar has been involved in the 24 hours of Le Mans since 1951 when a C-Type won the big enduro its very first time out.

This year, instead of seeking overall victory with a prototype, Jaguar is aiming for top honors in GT2 with a production-derived XKR built by Lansing, MI based Rocketsports Racing. The JaguarRSR XKR GT2 ran some practice laps at the Petit Le Mans last fall before its competition debut in the ALMS finale at Laguna Seca. RSR owner Paul Gentilozzi will share seat time with Scott Pruett and Marc Goossens in the 24 hour race. The XKR will also be running the full American Le Mans Series season this year starting at the 12 hours of Sebring next month.
