Jaguar chose the Pebble Beach Concours d’Elegance this year to show off what they claim to be a new concept car. But we know better than that…

The XJ75 Platinum Concept has been touted as a demonstration of the design customisation potential of the striking new XJ luxury salon, emphasising the Jaguar’s dramatic interior and exterior styling themes.

“The new Jaguar XJ Platinum Concept celebrates Jaguar’s 75th Anniversary, and highlights the uniqueness of the XJ, and more broadly, the increasingly personal nature of luxury cars in today’s market,” said Mike O’Driscoll, Managing Director of Jaguar Cars. “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.”

Dominated by a white and black contrast theme, the XJ75 Platinum Concept is a US=spec 470bhp 2011 Jaguar XJL Supercharged equipped with new ground-hugging front, rear and side sills. Painted a lustrous Satin Matte Pearlescent White, exterior chrome elements have been revised to either a dark chrome or gloss black. Bespoke 22-inch wheels are black and use a brushed contrast finish.

The contrast theme continues with gloss pearlescent white air vents, veneers and diamond stitch suede inserts to the seats and headliner, all set against the backdrop of a full Jet Softgrain leather interior. Suede and leather accents are seen throughout the interior to further material enhancements.

The XJ75 Platinum Concept centre console houses a bespoke clock developed and designed in partnership with the Bremont Watch Company. An independent British company, Bremont creates beautifully engineered and designed mechanical watches hand assembled in Switzerland.

“From a pure design perspective, the XJ75 Platinum Concept is foremost about emphasising the striking proportion and presence of the new XJ, with a distilled black and white theme, which conjures up the sense of precious platinum,” said Jaguar XJ Chief Designer Giles Taylor. “At the same time, the pure sporting character of XJ is brought to the fore by keeping the car’s clean graphic approach and further lowering its stance.

“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.”

Performance on the XJ75 Platinum Concept is derived from its 5.0-litre Supercharged direct-injection V8 with 470 horsepower and 424 lb.-ft of torque. In Europe the XJ Supersport gets the full 510bhp from the engine. Entertainment is provided by a 1,200-watt Bowers & Wilkins surround sound system with 20 speakers powered through 15 channels and state-of-the-art sound processing technology.

What we, and everyone else in the free-thinking world knows though, is that this is basically the new Jaguar XJR without the engine firepower. Jaguar has always provided an XJR range topper, and with their current meteoric rise in sales and popularity they are certain to capitalise on this.

This would be the hottest variant yet of the Jaguar/Land Rover 5.0 Supercharged V8, pushing out a rumoured 560bhp. With the looks of this concept and that engine, it is sure to be a hit.
