Introduction

The 2009 Jaguar XF is a new model, replacing the aging S-Type in Jaguar's lineup. This mid-sized, rear-wheel-drive sedan offers a fresh, engaging alternative to luxury imports such as the Audi A6, BMW 5 Series, Mercedes E-Class, and Lexus GS. After a 300-mile test drive, we'd rank the Jaguar XF near the top of its class. The Jaguar XF delivers everything you'd expect in a contemporary luxury sedan, and then some. The big news with XF is styling, interior design and features, though the hardware underneath is anything but ordinary. A lot of it, including the suspension design, is borrowed from the Jaguar XK. Factor in a well-engineered body structure, and the XF is exactly what it should be: smooth, quiet and responsive. It feels lighter and more agile than some of its competitors, and it bears up like a sport sedan when driven aggressively. The XF comes with a choice of two V8 engines. The base engine is Jag's familiar 4.2-liter V8, delivering 300 horsepower and 310 pound-feet of torque. The upgrade is a supercharged version of the 4.2, generating 420 hp and 408 lb-ft and surpassing nearly all competitors in output. Both V8s come with Jaguar's six-speed ZF automatic transmission, which is one of the best automatics money can buy. The XF will be offered in three trim levels, starting with the normally aspirated Luxury, which is better equipped than most base models in this category. The Premium Luxury adds even more stuff, including double-stitched, soft-grain leather on the dash and door panels. The SC (for supercharged) comes with just about everything Jaguar offers, including CATS automatic suspension control and 20-inch wheels. Then there's the racy new look. The XF marks a new direction for Jaguar, but it also continues some of the styling themes that have identified Jaguars for decades. The roofline and the shape of the side glass are intended to create the impression of a sporty, two-door coupe more than a four-door sedan, and to a considerable extent it works. The XF presents one of the more interesting designs in a category full of handsome automobiles. If you're intrigued by the photographs, you'll like it better in real life. The same applies inside. We really like the XF cabin, for both its look and overall function. Slide into this sedan, and an interactive greeting that Jaguar calls the handshake welcomes the driver and reminds him or her that driving is an active process. The wood, wool and leather create the feel and scent of a British club room, yet the design is light, airy and almost Scandinavian. The XF interior is more minimalist than its German competitors, but also more charming and easier to get familiar with. Of course, the swoopy styling has its drawbacks. By nearly every exterior dimension, the XF is slightly larger than all competitors, but the flow of its roofline and the rake of its rear glass mean rear headroom is tight. In general, the rear seat feels more confining than that in a Mercedes E-Class or Audi A6. On the upside, the XF's trunk is larger than any competitor's, and a folding rear seat further expands capacity. The importance of these packaging issues will depend on the buyer's priorities. In our estimation, the XF debuts as one of the most appealing cars in its class. Before the XF, well-heeled buyers seeking an option to the dense-pack switches, multi-layered interfaces and alphabet-soup of electronics in most imported luxo/sport sedans probably had to think about a brand with less cachet or dynamic capability. No more. With steady improvement in Jaguar's resale values and customer-satisfaction ratings the last several years, the new XF offers an excellent alternative. The 2009 XF replaces the 2008 S-Type in Jaguar's line-up, though the two cars will sell concurrently during calendar year 2008.

Walkaround

From its basic shape to its aerodynamic characteristics to its underlying structure, the 2009 Jaguar XF sedan is a thoroughly modern automobile. It's also a Jaguar, and while its styling is intended to create a template for Jaguars to come, the XF almost requires certain traits that the world associates with one of Britain's best-known brands. This essential Jaguar character is defined by the XF's face, and centered on a prominent grille that launches nearly all of the lines flowing rearward across the car. The grille itself is quintessentially British woven mesh, trimmed with chrome and reminiscent of the racing Jaguars that have performed so well in the 24 Hours of Le Mans. Wing-shaped headlight clusters wrap around the XF's corners onto its fenders. In profile, the XF is defined by a single, uninterrupted line that flows from the front bumper to the rear edge of the trunk lid. The beltline, that character-building crease below the side windows, rises up into the roof more than the roof drops down toward the beltline. The effect is a forward-biased wedge shape that creates an impression of speed, even when the XF is sitting still. The rear deck is higher than that on any Jaguar sedan before, but this less-formal look pays dividends in excellent aerodynamics and an expansive trunk. The overall shape of the XF does not shout Jaguar, but the familiar design cues are everywhere. Within each new-age headlight cluster sit two round, sealed beams that maintain the brand's quad-lamp signature, complete with the traditional fluting above the lights. The chrome trim above the side windows comes straight off the historic Mk. II sedan, while the prominent hood bulge recalls the E-type, which is arguably the most famous Jaguar of all. We're not enamored with all the jewelry, however. The bright metal strip on the trunk lid looks ordinary, and the leaping Jaguar in back is overkill. The XF's basic shape does more than create a high-impact presence. Aerodynamically, it's the most efficient Jaguar sedan ever, with an impressive 0.29 drag coefficient and a front-to-rear lift balance of zero. That means that neither end of the car is more inclined than the other to lift in the airflow as speeds increase. The excellent aerodynamics help keep the XF stable at high speeds, reduce wind noise inside and reduce fuel consumption at a given speed, compared to a car with more drag. The XF is slightly larger in just about every exterior dimension than the Audi A6, which was previously the largest car in this class. Its underlying structural design is driven by safety considerations, and particularly by the goal of protecting against side impacts and the tendency of tall, sport-utility type vehicles to slide upward in collisions with sedans. Jaguar has applied a host of high-tech metals, including high-carbon steels, dual-phase steel, hot-formed boron and bake-hardened steels, to create a vertical safety ring around the XF's occupant cell. The company claims that the XF will deliver the best crash protection in the class with a body/frame package that is lighter than that of its competitors. There's a second benefit to this careful structural engineering. While the XF's body is larger, Jaguar also claims that it is the most torsionally rigid car in the class, meaning that it flexes less from end to end under pressure. This overall stiffness and rigidity is one of the factors that separate luxury sedans from less expensive, higher-volume models. It's the foundation for minimizing noise and vibration inside an automobile, and the well from which dynamic capabilities such as handling, ride quality and overall responsiveness flow.

Interior Features

Inside, the Jaguar XF has everything we want in a sporting luxury sedan, without a lot of things we don't want. We want style, comfort, features, useful technology and great ambience. We don't want the distraction or annoyance that some contemporary luxury sedans demand in return for what we do want. Is the XF cabin high-tech? We'd say so. The overhead lights, for example, work simply with a touch. Not a switch or even a click of the light lens itself, but just a soft touch. The same with the glovebox latch, which isn't really a latch at all. It's a spot on the wood trim where you lay a finger. In general, the XF's features and controls empower the driver without overpowering. They're there when you need them and not a distraction when you don't (or when you do). That's in contrast to so many luxury cars that seem to want to shove all their goodies in your face, and then make them hard to operate. Like its exterior, the XF's interior will seem familiar to previous Jaguar owners, only different. The great leather and a choice of lacquered wood are familiar. The difference is primarily the design or layout. It's less conventional than previous Jaguar sedans, and perhaps less formal. The materials are bit different, too. There's a lot more aluminum trim to go with the wood (though there is still a lot of wood). And while Jaguar has always delivered the requisite leather, wood and wool carpet, it has sometimes hidden behind these big-impact materials without paying much attention to lesser stuff. In the XF, even the plastic pieces inside have a rich, latex-like feel. Overall, the package is first rate. It's as inviting in design and ambience as any car in this class, and more so than many. The only potential gripe in materials and craftsmanship is the headliner. It's a woven material Jaguar calls Morzine, and it's tailored snugly to the contour of the roof. It's just that the duck-like textile seems a bit ordinary in light of the great stuff everywhere else. All seats are leather, with perforated inserts between the bolsters. The base Luxury package gets what Jaguar calls bond-grain, and it's thick and sturdy. The Premium Luxury and SC models get soft-grain leather. It's ultra-soft to the touch, but still sturdy and substantial, and in these models it's applied on the dashboard and door panels as well, with genuine double stitching. The front seats are heavily sculpted, and they support and cushion as well as the standard seats in any car in this class, with adjustment for just about everything. Yet these seats are less massive than those in some competitors, perhaps thinner, so they seem to fill less space inside the car. When the driver slides into the XF with the proximity key in purse or pocket, the start button glows, ready to be pushed. The steering wheel is identical to that in the XK sport coupe: grippy, with heavy spokes and the growling mug of a jaguar in the center. The gear selector is a big, aluminum dial knob that rises from the center console when the XF fires up. It's cooler than the drive-by-wire shifters other luxury manufactures have developed, and as functional as any. Jaguar claims this electronic gear selector will keep working even if it's drenched with a half-gallon of coffee. The XF's primary gauges are slightly smaller than those in some luxury sedans, but the script is large and easy to read. They're clustered under a compact hood binnacle in the now-familiar luxo-car format: speedometer on the right, tach left, flanking an LCD message center with a bar-graph gas gauge, gear indicator, time, odometer and other trip information. The backlighting is ultra-crisp phosphorus blue, and perhaps the best going. Jaguar is bragging about the XF's soft blue LED ambient lighting, too. Unfortunately, our test driving came primarily during daylight, so we're not sure what to think. We can say that e
