Sharing the XKR's highly advanced lightweight aluminium body architecture, the high performance of the Jaguar XKR-S is made totally accessible by the enormous reserves of the 4.2-litre all aluminium four-cam supercharged V8's 420bhp (SAE) and 560Nm of torque.
With recalibrated engine management, the Jaguar XKR-S reaches an electronically limited top speed of 174mph (280kph) - 19mph (30kph) faster than the XKR. This additional performance is made accessible by improved aerodynamics (reduced drag and lift) and unique suspension set-up.
Sharing the XKR's class-leading six-speed sequential automatic transmission, the Jaguar XKR-S has exceptional refinement and the option of ultra-fast manual shifts controlled by steering wheel-mounted paddle shifts - with shift times measured in milliseconds to make this one of the fastest shifting transmissions in the world.
To match its increased performance, the Jaguar XKR-S adopts the most powerful brakes on any Jaguar production model, plus extensive changes to its suspension and steering to provide further enhanced ride and handling characteristics without compromising comfort.
The high performance braking system for the Jaguar XKR-S was developed by Jaguar's Special Vehicles team in partnership with British competition brake specialist Alcon, which supplies the stopping power for some of the fastest cars in the world, on both road and track. The brakes were perfected over thousands of miles of testing on some of Europe's most demanding roads, and by Jaguar's engineering team at the Nurburgring in Germany. The Jaguar XKR-S Alcon R Performance braking system features 400mm diameter discs on the front and 350mm discs at the rear. Each disc is radially ventilated for maximum cooling and to resist fade even under the hardest use, and will perfectly match the Jaguar XKR-S's increased top speed. The friction surfaces of each disc carry a series of crescent-shaped grooves that help clear water from the discs during wet weather and help to keep the brake pads clean at all times. The Alcon R performance brake package uses lightweight monobloc six-piston callipers at the front and four-piston callipers at the rear - each calliper finished in a distinctive red and carrying the R logo.
The Jaguar XKR-S coupe's dynamic balance focuses on achieving an even more sporting character while retaining the XKR's supple ride comfort. Its blend of control and refinement begins with the extremely stiff all-aluminium body structure, and a re-tuning of the XKR's all-wishbone suspension. The Jaguar XKR-S features new springs, new anti-roll bars and unique dampers. All the major suspension parameters are recalibrated, and the Jaguar XKR-S uses Jaguar's proven Computer Active Technology Suspension (CATS) with unique tuning. It also uses a faster ratio steering rack, for quicker reactions and optimum feel.
The limited edition coupé in Ultimate Black is identified by the unique Jaguar XKR-S badge on the rear of the car. The exterior of the Jaguar XKR-S has been subtly enhanced to make it recognisably different without being overstated. Another significant element in the revised handling package is that the ride height of the Jaguar XKR-S has been reduced by 10mm compared with that of the XKR, and the Jaguar XKR-S sits on unique, lightweight 20-inch Vortex forged alloy wheels with bespoke tyres. That naturally makes the Jaguar XKR-S look lower and even more sporting, but it has a number of other distinguishing details. It features a new front aerodynamic splitter, side sill extensions, revised rear spoiler and rear diffuser panel, with contrasting finishes to details such as the front mesh grille, power vents, sills and rear diffuser panel.
The Jaguar XKR-S has an Active Exhaust System, which is specifically tuned to ensure quiet, refined high-speed cruising while producing a much more hard-edged and sporting V8 sound under hard acceleration - not over loud, but full of performance character.
While the mechanical specification and the exterior revisions are driven largely by performance and dynamic enhancement, the interior changes reflect Jaguar's vision of the Jaguar XKR-S as an uncompromisingly luxurious sports car.
The full soft grain leather trim is finished in Charcoal with Ivory twin-needle contrast stitching, with leather wrapping the seats, instrument panel top, centre console, inner door panels and rear side panels. This is complemented by Piano Black veneer, Charcoal Alston luxury headlining, plus a revised instrument cluster - calibrated to accommodate the higher top speed - with XKR-S branding. The contrast-stitched leather trimmed steering wheel, alloy and leather gear selector with alloy surround, bright aluminium pedals, and XKR-S branded head-restraints, tread-plates and carpet mats further set the tone for this very special interior.
Taking Jaguar's 525W Premium Audio system with Pro Logic II surround sound as a starting point, renowned premium British loudspeaker manufacturer Bowers & Wilkins has tuned a signature speaker system specifically for the cabin of the Jaguar XKR-S. High output, low distortion Kevlar mid-range speakers and specially designed aluminium-dome tweeters deliver superb mid-range and extended high-frequency responses.
