THE PERSONALIZED JAGUAR XJ

There are a wide array of interior trim and equipment options on the 2007 JAGUAR XJ. Soft-grain leather trim with piping - now a standard feature of all JAGUAR XJ models - is offered in a variety of trim colors carefully coordinated with the range of body colors. Veneer selection includes the traditional Jaguar Burl Walnut on XJ8 L, a specialized Burl Walnut veneer with hand-inlaid Peruvian boxwood on Vanden Plas and Super V8, and newly optional Elm veneers which offer the choice of a lighter hue.

2007 JAGUAR XJ also offers versatile storage space, including a large glovebox with one-touch release offset towards the driver. As well as interior light and sunroof controls, the overhead console can incorporate the switches for features such as remote garage door opening and rear sunblind, microphones for the optional built-in hands-free telephone and JaguarVoice systems.

Jaguar is a leader in voice control technology, which can be used in the LWB to operate telephone, audio, air conditioning and satellite navigation functions, in several languages (with voice control as a dealer installed accessory). All JAGUAR XJ models now come standard with Bluetooth wireless technology for mobile phone connectivity.

Jaguar has embraced and developed many new technologies, but is careful to adopt them only when they are relevant and easy to use. Its DVD-based satellite navigation system is a good example of that philosophy. It uses a large, clear, touch sensitive screen with logical menus and commands to display points of interest, restaurants, hotels, parking facilities, Jaguar dealers and gas stations - the latter automatically highlighted when the fuel level is low. Touch-screen control also extends to the major audio and climate control functions.


THE POWER BEHIND THE LUXURY

The naturally aspirated version of the 4.2-liter V8 produces 300bhp at 6,000 rpm, with impressive mid-range flexibility and a torque peak of 310 lb.-ft. at 4,100 rpm.

Against the clock, this engine can accelerate JAGUAR XJ from standstill to 60 mph in just 6.3 seconds. However, paired with the advanced lightweight aluminum construction, it is also an engine that provides extraordinary fuel economy, with an EPA rating of 18/27 mpg (city/highway).

The mechanically supercharged 4.2-liter V8 that powers the XJR and Super V8 uses an Eaton supercharger, twin high efficiency intercoolers, a special twin pump fuel system, and forged oil cooled pistons to handle the increased internal loads and temperatures without compromising durability.

It produces a very strong 400bhp at 6,100 rpm, and a robust torque peak of 413 lb-ft at only 3,500 rpm. What's more, its exceptional torque spread delivers at least 86 percent of the peak torque figure across a very wide range, from 2,000 rpm to well beyond the peak point. Against the clock, it delivers 0-60 mph sprinting in just 5.0 seconds.

Both engines share similar construction, with aluminum alloy blocks and cylinder heads, designed for high strength, long durability and minimum transmitted noise and vibration. All use chain driven overhead camshafts with low noise, fine pitch, inverted tooth chains and sprockets.

Both the supercharged as well as the naturally aspirated AJ-V8 were equipped with Variable Camshaft Phasing. This continuously varies the phasing of the inlet camshaft according to demand, to optimize low speed torque and high speed power, while reducing emissions. High compression ratios and multi-hole injection nozzles improve combustion, improving fuel economy and further reducing emissions. Short engine and catalyst warm-up times make further gains.
