Jaguar Cars is adding even more appeal to the 'must have' XKR with the unveiling of the all-new special edition Portfolio model. The 4.2-litre supercharged sports car will be sold worldwide and each one will feature notable additions to the already strong specification of the XKR, which is capable of hitting an electronically controlled top speed of 155mph and can accelerate to 60mph in just 4.9 seconds.

The XKR's already powerful sporting styling cues – an enhanced front bumper, bonnet louvres and aluminium-finish grilles and side power vents – will remain and exclusive Celestial Black exterior paint and 20-inch polished Cremona five-spoke alloy wheels add to the overall presence.

The XKR's interior represents a truly sophisticated yet driver-focussed environment thanks to class-leading ergonomics, user-friendly in-car technology and simple, clear information displays in the instrument panel and main dashboard area.
 
The XKR Portfolio will combine this acclaimed design and performance with Jaguar's engineering and craftsmanship skills to take the XKR to an even higher level. Every XKR benefits from its class-leading, advanced aluminium construction, which ensures that its power is matched by a dynamic, lightweight chassis that handles supremely, rides exceptionally well and stops with surefooted reassurance time after time.

Jaguar's Special Vehicles team has worked alongside leading brake manufacturer Alcon to create the largest, most powerful brakes a production Jaguar has ever carried. After extensive testing by experts at Jaguar's specialist engineering centre (which is based next to the legendary Nürburgring race circuit in Germany), the new XKR Portfolio braking system was conceived.

A host of new additions to the interior further the luxurious look and feel of the XKR Portfolio. A unique, and quite beautiful, Engine-Spun aluminium veneer is standard on the Portfolio. A new alloy and leather gearshift selector, soft-grab door handles, contrast stitching throughout the cabin, leather-edged mats with a Jaguar logo and distinctive Portfolio treadplates on the doorsills complete the effect. The interior will also be the soft grain leather 'Luxury Sport Interior Theme' with seats in either warm charcoal (with ivory contrast stitching) or ivory (with charcoal contrast stitching).
 
The XKR Portfolio also marks another first for Jaguar: the first production example of its new partnership with renowned audio entertainment specialists Bowers & Wilkins. This world-leading loudspeaker manufacturer worked alongside Jaguar to create a stunning speaker system for the recent C-XF concept car, but the XKR Portfolio is the first production Jaguar to benefit from the relationship.

Taking Jaguar's 525W Premium Audio system with Dolby Pro Logic II surround sound as a starting point, Bowers & Wilkins have crafted a signature speaker system specifically for the XKR's cabin. High-output, low-distortion Kevlar mid-range speakers and specially designed aluminium-dome tweeters deliver superb mid-range and extended high-frequency responses.

The new Jaguar XKR Portfolio special edition is available to order from the end of March 2007 with deliveries expected later in the summer.
