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.

      Ooops... Maybe Jag had to do this to meet efficientcy regs overall in the US? But marketing wise and consumer wise bad...

        In the US and Europe. To their credit, it's just a V6, it's not like they're putting a Jag grille on a mainstream subcompact and tripling the price. Because that's a thing that happens.

      Idk maybe they did so the XJ could compete better with the BMW 740i. You know the one with the V6 in it.

      ALL of the German manufacturers offer their flagship platforms with a 6-cylinder engine. They sell more 6-cyl models than V8 models. Why shouldn't Jaguar give their customers the same option? It's actually a smart buy for a small business owners and execs who regularly lease or trade-in their vehicle every 3-5 years. These people spend most of their time in the car ALONE, crawling in TRAFFIC. So you get the luxury car and spend those hours in a nice interior with nice options, just getting better mileage. But it still has enough power to shuttle your clients to lunch when needed. Contrary to popular belief, most luxury sport sedans don't see regular high performance driving. If you're a driving enthusiast, you can still buy the supercharged V8 models.

      They're still keeping both versions of the supercharged 5.0L, it's only the NA 5.0L that's being dropped from the base car.

      I have a theory about this: I think Jaguar is be planning on introducing an XJR with the supercharged V8. They have already used the XJR nameplate for this type of thing in the previous generation, and they currently already have the XFR and XKR nameplates to denote their other supercharged V8 cars. So it'd be logical to dump the 5.0 out of the standard XJ lineup and bring back the XJR. But maybe it won't happen for MY2013.... it'd make sense to wait until MY2014 which is when the next refresh of the XJ is likely to happen.

      You want me to spend six figures or almost six figures for a V6? Uh hell no.

        Jonathan. This is your 3rd incorrect comment/response on AB related to luxury cars stats. Check your facts. That means you need to start reading.

      That 3.0 V6 diesel needs to be offered here!

      Okay.so Jag-ewww-waar has dumped their lovely V8, and replaced it with an econobox-style V6, then slapped on a turbocharger, which results in an engine that reduces the XJ's horsepower by 50, installed a start-stop system so we always feel like it's stalled, and didn't do a thing about the blah styling, and wants us to applaud because they improved the fuel economy of this car we're gonna pay close to a hundred thousand frikkin' grand to own by...14%. What, they think we can't afford GASOLINE??? Jesus H Christ...they could have left the car alone, and just dropped the price by five hundred bucks.

        You should get your facts right, ONLY the normally aspirated V8 is being replaced with the V6 (which by the way is super not turbo charged), the existing supercharged V8's (470bhp,510bhp) will continue in the lineup. An exterior facelift should come for MY 2014.

      wrond move if i can afford a $100k car of this class anything less than a V8 will not make it in the list though the 5.0L from Jaguar was not that impressive, i'd still take it over the V6 turbo it's not a 911 turbo, it's a luxury sedan and having to rev the crap out of it to get going is a no no

      I have to assume Jag will be able to manufacture the S/C 6 cheaper than the N/A V8, otherwise I'm not sure this makes much sense. That is, with Audi doing this recently, the assumption is the low pressure turbo V8 will take the middle ground between base S/C A8 and the S8, (but Jag has a huge gap between the S/C 6 and S/C 8 now). But, as we saw with the Audi having roughly the same mileage with their switch, using start-stop and the 8 speed likely would have made up the 14% difference in mileage alone.
