Russ Varney, Chief Programme Engineer, XK Series, explains the philosophy behind the uprated XKR: "With 510 PS and 625 Nm of torque, the XKR has immense reserves of power and acceleration which impress everyone who experience it. The car has always had the potential to reach speeds far beyond its original electronically limited maximum and many of our customers have expressed an interest in a car that can safely be driven faster where conditions permit. The new Speed Pack allows them to release some of that potential and give them control of the fastest Jaguar XK we've made to date".
The XKR Coupe featured at the Geneva Show on 4th March 2010 pairs both the optional Speed and Black Packs to create the bold new model, which also sports optional Piano Black veneers on the dashboard and red brake callipers.
The XKR Coupe with new optional Speed Pack allows customers to further strengthen their XKR's already impressive breadth of capability, by extending the car's top speed from 155mph (250km/h) to an electronically limited 174mph (280km/h) thanks to a unique engine and transmission recalibration.
To ensure the XKR with Speed Pack remains stable at high speeds, the coupe uses a revised front aerodynamic splitter and larger rear spoiler to provide increased balance and a reduction in lift. The XKR's computerised Active Differential Control also adjusts to reduce steering sensitivity at very high speeds, further improving stability and driver control.
Every XKR with the Speed Pack will come with body-coloured side sills and rear diffuser, and a chrome finish to the window surrounds, upper and lower mesh grilles, side Power Vents and boot lid finisher. Red brake callipers with a Jaguar 'R' logo sit inside 20-inch Kasuga alloy wheels.
Customers who order the XKR Coupe with the Speed Pack will be offered a paint palette that is part of the Jaguar Designers' Choice programme; a range of colours that have been specifically chosen to compliment the performance potential of the car. Seven colours are available on Speed Pack models: Ultimate Black, Polaris White, Salsa Red, Liquid Silver, Lunar Grey, Kyanite Blue and Spectrum Blue.
In addition to the Black Pack's exterior changes, the Jaguar Designers' Choice programme has also selected a range of interior trims that support the visual impact of the car. All XKRs with the Black Pack will be trimmed with Charcoal leather hides that can be personalised with a range of colour stitching and grain. Three interior finishes and veneers for the fascia and door trims are also available – Dark Oak, Dark Mesh Aluminium and Piano Black.
To underline the XKR's sporting credentials at 11MY red brake callipers become standard on all XKR Coupe and Convertible models.
A tyre repair Instant Mobility System (IMS) becomes standard on all XK and XKR models. This frees up the 30-litre wheel well, which is now carpeted and can hold a specially designed and tailored XK accessory suitcase, substantially increasing the versatility of the car.
In the UK, retail pricing of the XK range starts at £61,955 for the 5.0 n/a V8 petrol. The Speed Pack costs £3,500 and the Speed and Black Pack costs £4,000. Both are available on XKR Coupe only
