Jaguar has released details of revisions to the 2013 model-year XJ sedan, which encompass significant transmission, engine and dynamic changes meant to make the British luxury sedan both more efficient and more refined.
At the top of the change list is a new new 3.0-litre, supercharged V-6 engine. Producing about 335 horsepower and 332 lb-ft of torque in European spec – the highest specific power output of any Jaguar engine.
This new engine, which Jaguar describe as refined as well as powerful, will be employed in both the XJ and XF and it will also power the forthcoming F-Type sports car, which will make its debut in the 2013 calendar year.
As a further aid to efficiency, the XF will feature an eight-speed ZF transmission with Intelligent Stop-Start as standard fitment, all of which are said to contribute to an overall 14% improvement in fuel economy and CO2 emissions.
The 2013 XJ also features improved suspension refinement and performance, resulting from the re-calibrated spring and damper rate and remapped damper software. The result is enhanced ride isolation and passenger comfort on all road surfaces, according to Jaguar.
A 5.0-litre V-8 will continue to be offered.
