The British car maker said they will bring an exclusive XKR version at this year’s Goodwood Festival of Speed on July 2nd, and that is the Jaguar XKR 75 which comes to celebrate the company’s 75 anniversary.
With only 75 units to get built the Jaguar XKR 75 will extract power from a 5.0-litre supercharged engine delivering 530 PS and 655 Nm of torque, meaning that accelerating from nought to 60 mph will take 4.4 seconds and a maximum speed of 174 mpg could be reached.
What sets the Jaguar XKR 75 apart is the fact that under its skin the company’s performance coupe features an upgraded suspension which means better handling and the car’s new exhaust system offers new acoustics to match performance. 
The Jaguar XKR 75 price is 85,500 GBP and orders cand be placed starting from July.
Jaguar press release :
An exclusive XKR – the XKR 75 – will make its debut at the Goodwood Festival of Speed on July 2.
Jaguar Land Rover’s new CEO, Dr Ralf Speth, initiated the challenge to the Jaguar engineering team to construct an XKR to celebrate Jaguar’s 75th anniversary, which would deliver a combination of enhanced performance, superb chassis and steering control and grip levels to inspire the driving enthusiast to explore the true potential of the XKR’s capabilities.
Mike O’Driscoll, managing director, Jaguar Cars, said: "The XKR 75 will provide owners with exclusivity, excitement and a hint of Jaguar’s great heritage. This is a fitting way to celebrate the sporting credentials of the XK marque in the 75th year of the Jaguar name," he continued.
Jaguar engineers increased the power and torque of the acclaimed 5.0-litre supercharged engine to 530PS and 655Nm respectively for the XKR 75, to deliver truly outstanding performance. 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.
Using the rigid lightweight aluminium architecture of the XK as a solid foundation, theincreased power of the XKR 75 is matched by an agile, dynamic chassis that handles supremely, rides exceptionally well and stops with surefooted reassurance time after time.
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.
And with an improved acoustics package for the semi-active sports exhaust, the XKR 75 produces a pulse-racing growl to match its performance.
The car’s driver-focussed character, however, has not been achieved at the expense of the Jaguar traditional values of refinement and comfort.
"We conceived the XR 75 as a sports car with a duality of character that makes it perfectly suited to driving across Europe to the Nurburgring, completing some very fast laps, and then driving home again, added Mike Cross, Chief Engineer Vehicle Integrity.
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.
