The fastest ever Jaguar XKR coupe has been unveiled at next month's Geneva motor show.
The revised Jaguar XKR has a top speed of 174mph, raised from 155mph, and will be displayed with new performance and styling packs.
“With 503bhp and 461lb ft of torque, the XKR has immense reserves of power and acceleration," said Russ Varney, chief programme engineer, XK Series.
"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 speed pack - which costs £3500 - works via an engine and transmission recalibration, and to ensure the car remains stable at high speeds it sports a revised front aerodynamic splitter and larger rear spoiler. The Active Differential Control unit also adjusts to reduce steering sensitivity at very high speeds, further improving stability.
XKRs fitted with the speed pack will come with body-coloured side sills and rear diffuser, and a chrome finish to the window surrounds and upper and lower mesh grilles. In addition, the brake callipers will be painted red.
Buyers can also opt for a Black pack - available only in black, white or red body colours - which adds gloss black 20-inch alloys, and a gloss black finish on details such as widow surrounds and grilles. Interior changes include new colours of stitching. It costs £500.
In addition, all 2010 Jaguar XKR coupe and convertibles will be sold with red brake callipers as standard. All XKRs and XKs will also be sold with a tyre repair kit rather than a spare tyre - buyers can opt for an accessory suitcase to fit in the 30-litre wheel well.
