The unique full-length panoramic glass roof that floods the cabin with natural light allows the Jaguar XJ to offer an unrivalled sense of spaciousness and occasion for driver and passengers and at the same time retain the sleek coupé-like profile and lithe stance for which Jaguars are famous.

The mould- breaking styling is matched by similarly impressive construction techniques pioneered by Jaguar. The lightweight aluminium structure – 50 percent of which is made from recycled materials – offers improved fuel consumption and reduced emissions. In conjunction with a lifecycle approach to design and manufacture this allows the Jaguar XJ to minimise its carbon footprint.

The weight saved by the use of aluminium – an average of 150kg compared to its rivals – also has benefits for performance and agility and is complemented by the most advanced, powerful and efficient Jaguar powertrains ever. The choice of engines has been enlarged for the 2012 Jaguar XJ range with the fitment of a 3.0-litre V6 petrol engine (market specific). All engines are coupled to a shift-by-wire, six-speed automatic transmission controlled by the JaguarDrive Selector or steering wheel-mounted paddles.

The cabin of the Jaguar XJ blends elegant, contemporary design with the comfort, luxury and unmistakable sporting style of a Jaguar. Chrome and piano black detailing provides an eye-catching contrast to the beautifully-crafted leather and wood veneer surfaces.

Advanced new technology has allowed Jaguar’s interior designers to create an environment more akin to a state-of-the-art living space than a car cabin. Stunning 12.3-inch high-definition virtual instruments complement an innovative Dual-view 8-inch Touch-screen that allows the passenger to view DVD movies or TV programmes while the driver is provided with vehicle functions or satellite-navigation directions.

Subtle enhancements to the cabin are now available for the 2012 Jaguar XJ range to allow greater personalisation and flexibility of use. A new Rear Comfort Pack offers seats that now feature electric adjustment of the backrest recline angle, four-way lumbar support and a massage function.

On the long-wheelbase Portfolio derivative a new ‘Executive Pack’ transforms the rear of the Jaguar XJ into a high-speed mobile office space with the provision of fold-down laptop trays and an electric rear sunblind for increased privacy. The package also includes upgraded carpeting, combination wood and leather steering wheel, gloss wood veneer choices and chrome mirror housings.

All Jaguar XJ variants are now available with an Illumination Package derived from that offered as standard on the Supersport model. This comprises illuminated treadplates, boot latch and front and rear air vents.
