North American Jaguar XF models will get either a 300-horsepower, 4.2L V8 for 2009, or a supercharged 4.2L V8 worth 420 horsepower. With either engine, the XF has rapid acceleration on par with some of the fastest German sports sedans. According to Jaguar, the standard XF can accelerate to 60 mph in 6.2 seconds while the supercharged model can do it in just 5.1 seconds. The XF's gear selector uses a unique rotary design that Jaguar claims is intuitive and also saves interior space; it includes a Sequential Shift System, which enables the driver to command gear shifts of the six-speed automatic transmission with steering-wheel-mounted paddles. With the best torsional stiffness in its class, according to Jaguar, the XF is able to offer impressive handling and performance while also allowing a smooth and well-controlled ride. Variable ratio power-assisted steering offers reduced effort while parking plus better control at high speed. The interior departs from the typical luxury-car mold with a new design direction. As with other Jaguar models, the XF has high-grade materials-including supple leathers and a striking matte-metallic finish. The XF also has a choice of real wood veneers, including Satin American Walnut, Burl Walnut, or Rich Oak, with aluminum highlights. Air conditioning vents are completely flush with the dashboard until the ignition is switched on, when they rotate to an open position, overhead console lamps operate through a special touch- or proximity-sensing system, and the interior is bathed in cool blue lighting at night. There are various storage compartments inside, and front cup holders are large enough for a 44-ounce beverage cup. The available top-of-the-range, 440-watt Bowers & Wilkins Premium Sound System has been specifically designed for the XF's cabin; it has surround sound processing, 14 speakers, a remote amplifier, and Kevlar speaker cones. The XF's audio systems are fully compatible with portable audio players or USB memory sticks. An extensive list of electronic driving aids is offered on the XF, including anti-lock brakes with electronic brakeforce distribution and cornering brake control. The electronic stability control system includes Understeer Control Logic, which decelerates the car and helps restore grip in extreme maneuvers or in the loss of traction. The XF's dynamic stability control system offers two different modes, including a "Trac DSC" mode that allows more slip before intervening, for more enthusiastic driving. XF models also offer a winter driving mode. Available high-tech features on the XF include front and rear parking aids, a blind-spot monitor, adaptive cruise control, and voice-activated controls for the navigation system and hands-free calling interface. The all-new XF replaces the S-Type in Jaguar's 2009 lineup and takes a dramatic new design direction with a sportier focus. Performance; stunning interior appointments; wide range of quality materials. Jaguar's 2009 XF, with its sleek, coupe-like shape, sport-sedan performance, and stunning interior, competes very well with models such as the BMW 5-Series, Lexus GS 460, and Mercedes-Benz E-Class. It also boasts higher-grade materials such as those available in more exclusive vehicles. And like other Jaguar models, the new XF also promises a uniquely British personality compared to other luxury cars.
