Ever fancied installing a bodykit on your stately Jaguar XJ sedan? Probably not, but in case you did Jaguar has unveiled a range of new body enhancements for its big luxury sedan at this week’s 2011 Dubai Motor Show.

The enhancements are grouped in two new packs, a basic Sport pack and high-performance Speed pack. The Sport pack is available on all current XJ models except the 510-horsepower Supersport, while the Speed pack is only available on supercharged models already fitted with the Sport pack.

Now that we have that out of the way, let’s take a look at what Jaguar’s new packs have to offer.

The Sport pack comprises a number of exterior and interior design options including a full bodykit, unique 20-inch alloy wheels, red painted brake calipers, sport seats front and rear, and new trim choices.

Key features of the fully functional bodykit include a new front splitter to reduce lift, as well as a rear lip spoiler. While ensuring optimal stability at high-speed, the Sport pack also maintains the standard XJ's sleek 0.29 Cd aerodynamic figure.

In conjunction with the Sport pack, the new Speed pack raises the XJ’s electronically limited top speed of 155 mph up to 174 mph. You’ll note that this is the same top speed as some of Jaguar’s special edition XKR coupes but not quite as high as 186 mph Vmax of the potent XKR-S.
