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.  

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.  

All seats are leather, with perforated inserts between the bolsters.   The base package gets what Jaguar calls bond-grain, and it's thick and sturdy.   The Premium 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 everything on the dashboard, including the standard touch-screen control panel, is easy to read in bright Arizona sunlight, even with sunglasses.  

Speaking of the dashboard, it's not the familiar rounded-end flat panel we've come to expect in Jaguar sedans.   It's lower and, thanks partly to the long rake of the windshield, much deeper.   The design is dominated by a strip of scored aluminum, perhaps six inches high, that runs the full width and around onto the door panels.   The leather top of the dash rises slightly from this aluminum plate toward the base of the windshield, stretching a good two feet at the center of the car.   Below the aluminum is a thinner strip of wood, with big planks of wood trim on the doors and the top of the center console.   The XF offers a choice of satin-finish American Walnut, glossy, traditional Burl Walnut, or lighter Rich Oak.  

Switches and general ergonomic function are first-rate; the best we've experienced in a Jaguar, and near the top among luxury imports.   Pressure-resistant thumbwheels on the steering-wheel spokes adjust audio or cruise-control functions, and they feel right.   The headlight switch is on the turn-signal stalk and the wipers are on the right stalk, and both are easy to use, first and every time.   Buttons for the sunroof and rear sunshade are overhead.  

In general, the XF has exactly what we look for and like.   The mirror adjustor and window switches are clustered on the armrest, and easy to operate with the forearm laid flat.   The elbows rest level on the door and center armrests when the hands are placed at 10 and 2 o'clock on the steering wheel, for comfortable, relaxed cruising.  

Nothing about the XF's various controls seems daunting, even at first blush.   There's no dense array of buttons or annoying point-and-click device to learn.   Every model comes with a good-sized touch-screen LCD (even without the optional navigation system), and it's within easy reach right in the middle of the dash.   It's the primary interface for audio, navigation and communication functions, and its menus are straightforward and easy to learn.   There's also a prominent hard button that immediately returns you to the main menu.  

Better still, all frequently adjusted controls are replicated in a rational, attractive array of buttons just below the touch-screen, in the short center stack.   Two rectangular clusters control audio and climate adjustments, with substantial radial knobs for volume and fan speed.   Virtually every important adjustment can be undertaken with one button and one step.   It's this balance between simple and in-depth adjustment, or complicated systems with easy interface, that sets the XF apart from many of its competitors.  

We like the available audio systems almost as much.   Even the base stereo features eight speakers and 320 watts of output.   The available 440-watt Bowers & Wilkins audio system might be the best we've heard in an original-equipment automotive application.   It was developed with B&W, the British boutique manufacturer that makes speakers and monitors for recording studios.   The highs are incredibly crisp and the lows are pervasive, with virtually no muddling or distortion at either extreme, even at mega-wattage.  

Jaguar claims the XF has more front-seat storage space than any car in its class.   That's another way of saying storage options are decent, but still not up to snuff with some less-expensive mainstream sedans and family vehicles.  

The XF's center console is wide, almost as we'd expect in a big sports car.   Touch-release covers reveal three easy-to-reach cupholders, the largest of which will safely hold a super-size drink cup.   With the round inserts removed, there's plenty or room in these bins for phones, remotes and wallets.   The main bin in the center console isn't large enough to hide a standard-size laptop, but there's plenty of room for cameras or a lot of CDs.   There's also an easy-access power point and iPod/auxiliary jack, with a secure place to leave the plugged-in MP3 player while driving.   The glovebox has about twice as much space as that occupied by the owner's manual and documentation.   The glovebox in some luxury sedans won't even fit the owner's manual, while others are filled by it.   Bins at the bottoms of the doors aren't very deep, but they're wide enough to lay a phone flat and they are lined with a velvety material that keeps glasses and other delicate items from sliding or scratching.  

If the XF's accommodations fall short of the competition, it's behind the front seats.   The rear seat itself is comfortable, bolstered some for the outside passengers, with the same fine materials as the front part of cabin.   Yet the rear space seems more confining than the roomiest cars in this class, regardless of what the published measurements suggest, and it's a bit short on amenities.  

A big part of the problem is the XF's diving roofline and long rear window.   The rear seat is placed fairly far forward toward the center of the car, so legroom is tight, particularly with anything but short occupants in front.   And headroom still comes up short.   A passenger taller than 5 feet, 7 inches will sit in back with hair brushing the headliner.   Tall passengers might have to contort their necks in some fashion.   Cupholders are provided in the fold-down rear armrest; a pair of vents on the back of the front console offer ventilation, and there's a storage bin big enough for some change or a pack of cigarettes and not much else.   The only other storage space for rear passengers is a small bin at the bottom of each door.  

The trunk, on the other hand, is easily the largest in this class.   With 17.7 cubic feet of space, it's essentially as big as the trunk in some full-size luxury sedans such as the BMW 7 Series.   Loading large items could take some work, however, and again the XF's styling is partly to blame.   The rear deck or trunk lid is fairly short, and a lot of the cargo space stretches forward under the rear window, so the trunk opening is fairly small.   The lift-over height seems higher than average, as well.  

To add cargo capacity, the XF is equipped with a split, folding rear seat, with clever releases that will lower the seatbacks from the trunk, without going inside the car.   This expands cargo space another 14.8 cubic feet, for an impressive total of 32.5 cubic feet.   Perhaps as significantly, the folding seat allows alternate access to the cargo area, by leaning in through the rear side doors.  

The exterior design plays a role in our biggest single gripe inside the XF: Outward visibility.   We wouldn't call it bad, but in any direction other than forward, the view out is more restricted than we'd expect in a sedan.   The rear glass is expansive, but it's raked at a long, flat, coupe-like angle, so the view through the rearview mirror is short.   The side mirrors aren't small, but they seem to be shaped more for style or noise reduction than optimized visibility.   Bottom line: It takes a while to get comfortable with the mirrors, or to get them set in a fashion that minimizes over-the-shoulder glances in traffic.   However, the performance of this car suggests the driver may not have much need to worry about what's behind, except when backing up.  

Rear park assist solves that problem, with audible beeps and a graphic display on the touch screen.   A reverse-view camera is optional, and we strongly recommend it because it could help the driver spot a child or adult behind the car and thereby avoid a tragic accident when backing up, especially given the relatively high rear deck and the narrow view through the rear window.
