While we are all well aware of just how great of an automobile that the Jaguar XFR really is, the luxury car builder has announced details about an upcoming alternatively fueled model of the XF->ke1236 sport sedan for 2011 that brings the same high performance attitude and upscale amenities of the top of the line version into a new diesel burning four door dubbed the XF S.

The XF S is powered by a 275 HP diesel mill that promises not to disappoint drivers thanks to the Jag's Adaptive Dynamics system, a unit that is currently featured on the XFR and XK->ke1153 that constantly adjusts the suspension to improve handling without giving up an ounce of comfort. The result improves on the XF's already impressive handling and strikes a clever balance between a luxury ride and sports car agility, which will be an option on the high performance diesel.

The exterior of the new Jaguar XF S can be upgraded with a new aerodynamics package similar to the XFR's which includes black mesh grill inserts, horizontal blades across the lower air intakes and bolder side skirts. Meanwhile the interior features upscale touches like high gloss Piano Black veneer and a Jet Suedecloth headliner that is available as an option on Premium Luxury and Portfolio Diesel S models; ensuring that you don't have to give up style and luxury just to be green.

The 275 PS high-performance XF Diesel S model is significantly enhanced for MY11, taking the lead from the stunning XFR model to provide drivers with superior driving dynamics, a more striking appearance and an upgraded interior which offers the ultimate in sporting luxury.

The MY11 XF Diesel S now comes with an XFR derived interior as standard while the Adaptive Dynamics system, currently featured on the XFR and XK range, is available as an option on the high-performance diesel.

“We have applied the lessons learned from the XFR to bring more sophisticated, sporting driving dynamics to the Diesel S model,” explained Mike Cross, Chief Engineer, Vehicle Integrity. “Fitted with the state-of-the-art Adaptive Dynamics system, the latest Diesel S provides driving enthusiasts with taut handling and superb body control, but without the noise and harshness often associated with ‘sports’ suspension packages.”

Jaguar’s Adaptive Dynamics system is featured in one of the two new option packs which are available exclusively on the XF Diesel S in 2010 to further enhance the driver's enjoyment of the performance characteristics of this car – the Dynamics Pack and the Aerodynamic Pack.

Dynamics Pack.The Dynamics Pack incorporates the Adaptive Dynamics system. This high-tech system analyses chassis movement and driver and wheel inputs 500 times every second, continually adjusting the suspension to improve handling without loss of comfort. The result improves on the XF's already impressive handling and strikes a clever balance between a luxury ride and sports car agility. This optional pack also includes Shadow or Silver finish 20-inch Volans five-spoke alloy wheels, and costs from £1250 depending on model.

Aerodynamic Pack. The Aerodynamic Pack is designed to give an even bolder style to the XF Diesel S. The striking new black mesh inserts for the grille and lower air intakes give a fresh look to the front of the car and for even greater visual impact, the sculpted lower air intake blades can be supplied with bright-white LED daytime running lights. The side sills from an XFR complete the package. The cost of this option pack is £1500, or £2000 with the LED lights.

Performance Interior. The enhancements to the MY11 Diesel S are completed by the interior, which now features the superior specification from the XFR as standard, providing the 275 PS diesel model with the ultimate sporting luxury interior. The upgraded cabin includes the leather sports seats from the XFR, featuring 18-way adjustment for the driver and 14-way for the passenger. Power-adjusted raised side bolsters will keep driver and passenger firmly in place during cornering, while the rest of the cabin's sporting style is enhanced with the high-gloss Piano Black veneer and Jet Suedecloth headlining available as an option on Premium Luxury and Portfolio Diesel S models.
