The Jaguar XF is offered in six basic models--XF 2.0, XF 3.0 Sport, XF 3.0 Portfolio, XF Supercharged, XFR and XFR-S. The base 2.0 model comes with a 240-hp, 2.0L turbocharged four. A 340-hp, 3.0L supercharged V6 powers the XF 3.0. XF Supercharged models features a 470-hp, 5.0L supercharged V8, while towards the top of the lineup is the high-performance XFR, with its 510-hp high-output version of the supercharged V8. The XFR-S has the same supercharged 5.0L but is tuned to make 550 horsepower. All models come with an 8-speed automatic transmission. XF 3.0 models offer Jaguar's so-called "Instinctive" all-wheel drive system. These models include an active torque-management system--including a wet, multi-plate clutch--with power sent to the rear wheels during normal driving that can shift some to the front wheels when needed for traction and stability. The system also includes a Winter Mode that pre-loads more torque to the front wheels for better adverse-weather traction. The XF 2.0's impressive engine provides the driving feel of a V6, thanks to a torque peak of 251 lb-ft reached at just 2,000 rpm--0-60 comes in only 5.7 seconds. It manages EPA ratings of 19 mpg city, 30 highway-- impressive for any luxury car. At the other end of the lineup, top XFR-S models can reach 60 mph in 4.4 seconds, and get to an electronically limited 186 mph. Fuel economy for the XFR-S is the same as that of the XFR-- 15 mpg city and 23 mpg highway. All models include steering-wheel shift paddles for performance and control. Step up to either the XF Supercharged or the XFR or XFR-S, and it also comes with an Active Dynamics active-damping system that helps filter out bumps and irregularities while enabling an even firmer suspension for control under high-performance driving (as maximized with the 'Dynamic' setting). These two models also add an Active Differential Control to help get engine power out most efficiently through the rear wheels. All XF models, from the entry-level XF 2.0 to the top-of-the-line XFR-S get essentially the same beautiful exterior--although the high-performance XFR stands out from the rest of the lineup due to its special aero package, a larger, lower grille in black mesh and outboard air intakes. A louvered hood and bright-finished tailpipes complete the look, while inside there are special 'R' embossed sport seats. The XFR-S adds some unique aerodynamic touches. Made largely of carbon fiber, these enhancements actually reduce lift by 68 percent, according to Jaguar. The XFR-S gets serious suspension improvements as well as track-oriented calibrations of the stability control and active differential. The XFR-S gets 20-inch forged alloy wheels and a Meridian 18-speaker sound system standard. Cabin appointments in the XF are sporty yet very soft and luxurious, with leather upholstery plus an aluminum dash with satin- or gloss-finished wood veneers, tailored door panels and blue ambient lighting. On startup, the rotary shift selector rises from the center console and rotary dash vents automatically open. Even the base XF 2.0 models come with a strong list of luxury features, including leather heated power seats, power heated mirrors, dual-zone automatic climate control, a power moonroof and keyless push-button start. With a Cold Pack the steering wheel is heated, as is the windshield and Supercharged and XFR models include heated-and-cooled ventilated front seats. A Convenience Pack adds an Interactive Voice system, a Blind Spot monitor system, a power rear sunshade and intelligent high-beam headlamps. Adaptive Cruise Control is also available as an option, and 2015 XF models with the navigation system get several additional features: My POI (for point-of-interest searching and lists), Visual Lane Guidance (for help at intersections) and Dynamic Zoom (for a magnified image of an intersection or interchange).
