Jaguar has just officially debuted its 2013 XJ, which, while it remains the same esthetically, gets an updated chassis, powertrain and technical features.

Power for the outgoing model is a 5.0-liter V8 engine, which is being replaced with a 3.0-liter supercharged V6. The new motor will produce 335 hp and 332 lb-ft of torque, with a 0-60 mph time of 5.7 seconds. Fuel economy figures have been placed at a combined figure of 25 mpg. The previous engine made a 0-60 mph time from its 380 hp and 380 lb-ft of torque. This new engine will also be shared with the new F-Type Roadster.

Jaguar’s new 3.0-liter V6 will be mated to an also new 8-speed automatic XF transmission on all of the XJ variants. ‘Intelligent Stop-Start’ will also be included.

The 2013 XJ will also feature a new 825W sound system, developed in conjunction with Meridian that will be offered as an option, and will come standard on the Supersport and Portfolio variants.

The british automaker also recalibrated the spring and damper tunes with remapped software.

No U.S. pricing or release date is available at this time, but the 2013 XJ goes on sale in Europe in September.
