Jaguar engineers increased the power and torque of the 5.0-litre supercharged engine to 530PS and 655Nm respectively for the XKR 75. While the limited edition model's top speed is electronically limited to 174mph (280km/h), the XKR 75's 0‐60mph (100km/h) acceleration time is reduced from 4.6 to 4.4 seconds compared to the standard 510 PS XKR.
The Jaguar XKR 75 features revised suspension and handling for increased precision and agility in addition to the performance enhancements. To ensure the XKR 75 remains stable at high speeds, a revised aerodynamic body pack with a front splitter, side sills extensions, a rear diffuser and larger rear spoiler 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.
The XKR 75 features a new Stratus Grey finish. Red brake callipers contrast the eye-catching 20-inch gloss Vortex forged lightweight alloys with a dark technical finish and diamond turn. Customers will have the option to apply a unique body graphic that runs from the front bumper to the rear haunches.
The XKR 75's interior completes the driver-focussed performance environment finished in Charcoal with ivory stitch, piano black finish to facia and centre console and a Jet suedecloth headlining.
Production of the XKR 75 will be limited to just 75 vehicles, which will be available to order from July 2010 in the UK priced from £85,500 OTR. Customer deliveries will commence during October.
