Jaguar has announced a few updates for the 2013 XJ, the most significant of which is the availability of an all-new supercharged 3.0-liter V6 engine. The six-cylinder is good for 335 horsepower and 331 pound-feet of torque and is bolted to a new eight-speed automatic gearbox with a start-stop function. All told, the changes should help the big four-door yield a 14 percent improvement in fuel economy over the old naturally aspirated 5.0-liter V8 and its six-speed transmission.
While no Environmental Protection Agency numbers have been released as of yet, our quick math indicates the 2013 XJ could crank out 18 miles per gallon city, 26 mpg highway and 21 mpg combined. That fuel economy does come with a price, however. The delicious 5.0-liter V8 currently serves up 50 more horsepower and 49 more lb-ft of torque compared to the new force-fed six.
In addition to the drivetrain changes, Jaguar reworked the spring and damper rates for better on-road comfort, and a new 825 Meridian sound system is also part of the mix. Check out the full press blast below.

Jaguar has announced details of its 2013 model year generation XJ. It benefits from Jaguar's relentless research and development programme to improve efficiency and introduce the latest comfort and functional technologies.
Significant transmission, engine and dynamic developments mean Jaguar's most technologically advanced car becomes more efficient and refined.
To maximise efficiency from the all-aluminium architecture of the XJ, Jaguar has introduced an eight-speed ZF transmission with Intelligent Stop-Start as standard. As seen on the XF, these developments lead to lower fuel consumption and emissions. The new XJ is expected to achieve 47 MPG while emitting 159g/km of CO2, a 14% improvement.
The 13MY XJ marks the introduction of a new 3.0-litre, supercharged V6 powertrain. Producing 340PS and 450Nm of torque - equating to almost 127PS per litre - the highest specific output of any Jaguar engine, the new engine is refined and powerful. Making its debut in the XJ and XF, this engine will also power the forthcoming F-TYPE sports car, available from 2013.
For 13MY, XJ has improved suspension refinement and performance. Alongside the exciting new powertrain line-up all models in the range benefit from re-calibrated spring and damper tunes as well as remapped damper software - offering enhanced ride isolation and passenger comfort on all road surfaces.
Enhancements extend to the XJ's award-winning cabin with DAB now fitted as standard and a new premium sound system.
Teaming up with British audio specialist Meridian, Jaguar engineers have developed a 825W sound system. Tested using the most scrupulous audio measurements the Meridian system boasts significantly lower levels of harmonic distortion - meaning a lower power output is required to achieve the high levels of audio clarity within the vehicle. The top-of-the range 20-speaker 825W system comes as standard on Portfolio and Supersport XJ models while offered as an option on other derivatives.
The XJ continues to be among the best-selling cars in its class, reporting an 11% per cent rise in sales in 2011. Combining advanced construction, luxury and performance, the XJ range has recently expanded to include the new Sport and Speed packs as well as the introduction of the new 'Ultimate' model, including a bespoke rear seat environment and unique exterior styling.
