Only 10 examples of the 2008 XKR Portfolio will be made available in Australia - all of which in Coupe style, carrying a price tag of $246,000.
Performance remains unchanged from the standard XKR - which was hardly lacking in the first place, accelerating to 100km/h in just 5.2 seconds and onto an electronically limited top speed of 250km/h.
Stopping power however has been significantly upgraded with Jaguar Special Vehicles collaborating with brake manufacturer Alcon to develop the largest, most powerful brakes a production Jaguar has ever carried.
The exterior has also been enhanced with performance styling cues including an exclusive Shadow Grey exterior paint, milled aluminum side power vents and 20-inch Selena five spoke alloy wheels in shadow finish featuring red Jaguar "Heritage" centre badges.
Inside, Jaguar has honed the XKR's premium 525W sound system from Bowers and Wilkins with Dolby Pro Logic II surround sound, adding high-output, low distortion Kevlar mid-range speakers and specially designed aluminium dome tweeters to deliver superb mid-range and extended high-frequency responses.
The cabin also receives added interior refinements including an alloy gear lever and selector gate surround, leather edged floor mats, premium headlining and the choice between warm charcoal leather trim with cranberry contrast stitch or Ivory and charcoal leather trim with slate blue contrast stitching.
"We received a phenomenal response last year when the XKR Portfolio was released. The specification is quite unique, and very special. It combines breathtaking performance and dramatic beauty with exclusive, individual touches of craftsmanship and equipment that lift it to another level. The XKR Portfolio continues our program our creating exclusive bespoke vehicles for our customers"
While these changes may seem modest - the standard XKR retails for only $5,900RRP less than the Portfolio edition, certainly a small premium for ultra-exclusivity and added luxury.
