The one-off concept car has been designed to highlight the customisable potential of the luxury saloon and features the dramatic styling cues inside and out.
The Platinum name is derived from the ‘Satin Matte Pearlescent White’ exterior colour and matt gloss and dark chrome features to create an effect similar to that of the precious metal.
Exterior styling tweaks include white front, rear and side sills to give the XJ75 a lower stance and matt black bespoke 22" wheels.
Inside, the interior has been fitted out with high quality materials in the same black and white theme. This includes leather upholstery with suede and leather accents, diamond stitching and glass white air vents and veneers.
The design team included a top-of-the-range surround sound system complete with 20 speakers powered through 15 channels. The dashboard clock is a unique handmade model built to order in Switzerland by British company Bremont.
Jaguar XJ Chief Designer Giles Taylor said: "On the inside, we played up the XJ’s combination of high-end materials and British flair to really have some fun.
"The XJ75 Platinum Concept is a design exercise that shows our vision of customization as an inspiration for those enthusiasts who have a taste for strong individuality and visual confidence in their luxury automobiles."
Aside from the design elements of the concept, the supercharged model features a 5.0-litre V8 engine offering 470 horsepower and 424 lb-ft of torque.
The model is the first ever example of a customised XJ75 concept car and Managing Director of Jaguar Mike O’Driscoll said: "The XJ is thoroughly modern, and captures the innovative and daring character that our founder Sir William Lyons built into every Jaguar. And the design team clearly had some fun making their first one-of-a-kind XJ design concept in that spirit."
The XJ75 Platinum Concept appeared at the US show at Pebble Beach for the first time and Jaguar has now released a series of images of the luxury saloon concept.
