2010 BMW X5

High-performance X5 M joins lineup. edited by New Car Test Drive

Walk Around

The X5 sport-utility vehicle is BMW through and through. On the road, that means an emphasis on sporty driving dynamics, even if it comes at the expense of utility. Sitting still, it means the X5 looks like a taller, ganglier BMW sedan. The diesel-powered X5 xDrive35d looks the same as its gasoline-powered siblings from its twin-kidney grille to the clamshell hatch in back.

There's no mistaking the X5's classic BMW look. It starts in front, with that trademark grille and familiar dual-dual lamp clusters. Super-bright adaptive xenon headlights come standard. On the X5, they're ringed with LED circles that serve as the daytime running lights (and look really cool). These headlights level themselves when the X5 bounces over bumps, and turn slightly with the steering wheel. The standard fog lights also work as cornering lamps, lighting when the corresponding directional signal is selected. The M model deletes the fog lights in favor of larger lower air intakes and more prominent grille openings. The M also has a different, more angular lower fascia.

In profile, the X5's big wheels and short overhangs promote an agile look, while the roof and taillights trail into a slightly flanged lip. These so-called separation edges smooth air as it rushes over the back of the vehicle. That means a slight improvement in fuel economy, and probably more significantly, less wind noise inside the X5. The M differs from the other two models with side ?gills? behind the front wheels and a unique 20-inch wheel design.

Indeed, with a drag coefficient of 0.34, the X5 is an aerodynamically efficient vehicle, as tall, boxy SUVs go. Its underbody is smoothed with various fairing devices. The front spoiler directs air around the front tires, reducing resistance as the X5 punches a substantial hole in the air. With its sportier suspension, the M model sits 0.4 inch lower than the others.

BMW tried to increase the X5's utility when it redesigned it for 2007, stretching it seven inches to add rear legroom and cargo space. By wheelbase and overall length, the X5 now sits mid-pack among key competitors: Slightly larger than the Acura MDX, Land Rover LR2, Mercedes M-Class and Volvo XC90, and quite a bit smaller than the Audi Q7, and Lexus GX.

At the rear, the M model has a slightly altered appearance. It features a different lower fascia with an integral rear diffuser that surrounds quad exhaust outlets. All models have a clamshell tailgate that is a mixed bag, in our view. The lower third drops down, once the upper portion has been lifted up. On the plus side, the split design is handy for dropping smaller packages in the back. The little tailgate keeps items from falling out when you open the hatch, which can be a problem on some SUVs with a single liftgate, and it provides a nice (though high) bench for changing shoes or just resting a moment. The problem is that the upper portion includes not only the glass, but also half the metal that comprises the rear of the vehicle. In other words, it's the heavier, more substantial portion of the gate. It takes more effort to operate than it would if only the glass opened up and down. The optional power tailgate helps in this respect, and we recommend getting it.

Interior

2010 BMW X5

The X5 cabin has typical BMW ambience: a combination of sporting, character, wood- or aluminum-trimmed luxury and lots of things to adjust.

Nothing inside the X5 makes it feel like an SUV, beyond its relatively high seating position. Measured by overall fit and finish, the X5 compares favorably to luxury brands such as Infiniti and Mercedes.

Panels and pieces inside the X5 fit impeccably. Most surfaces have a rich feel, and the seats are perforated to enable the active ventilation option. Standard line models are available with aluminum or one of three wood-trim packages: dark-stained bamboo (almost black), dark-stained poplar (the most traditional), and light-stained poplar (essentially blonde). The vinyl dash and door panels in our test X5 were a single, dark tone, rather than the two-step dark/light treatment increasingly common in BMWs and European brands in general. We liked the overall appearance, though the monotone creates a serious, no-frills feeling.

The front seats are excellent: comfortable and exceptionally supportive, once they're tailored to whoever is sitting on them. The optional Comfort Seats and the M's sport seat have a lot of side bolstering for this type of vehicle, and that's a double-edge sword. It's great for drivers about to take a spirited run through the canyon, but less so for passengers, and particularly the elderly, who have to climb up into the X5 and then slide over the bolsters into a front seat. Seat adjustment comes via BMW's usual extensive array of controls, including double-hinged, articulated seat backs and various bolsters that can be squeezed or pumped up. They all work well, but there are so many that fine tuning takes time and some trial and error. The memory feature, which comes standard, is handy once the driver has found a comfortable position. It can take a while.

The dashboard applies a taller variant of BMW's stepped or stacked design, and it looks tidy in the X5. It certainly isn't cluttered, as it can be in some vehicles in this class, thanks partly to BMW's point-and-click iDrive control. Now in its fourth generation, iDrive is improved for 2010. Around the familiar round aluminum knob on the center console, this generation adds Menu, CD, Radio, Tel, Nav, Back, and Option buttons. The previous generation had only a Menu button. This system controls navigation, communication, climate, and entertainment functions, and the new buttons make accessing many controls easier and quicker. It can still require several steps to perform various functions, making tasks like finding a new radio station overly complicated, but we find the latest generation easier to use than its predecessor. We also found that it becomes easier once you get used to it.

Unfortunately, there are still too many things you can't adjust without delving into the iDrive menus. Audio tone, for example. The optional premium stereo sounds fantastic, but we were discouraged from taking full advantage of its sound processing features because of the tedious, distracting iDrive sequence required to set them. Those who frequently switch between talk radio and music may find this inconvenient.

One of the best things about the iDrive-equipped X5 is that it has conventional switches for temperature adjustment, fan speed and airflow, and for some audio functions, with a genuine volume control. In other words, you can make these frequent adjustments easily without fishing through iDrive. There are also phone and redundant audio controls on the steering wheel spokes. Cruise-control functions are located on a third stalk on the steering column, with wipers on the conventional, right stalk and a trip computer button on the left, turn-signal stalk. We find BMW's electronic turn signals among the most cumbersome in any luxury brand, to the point where you're tempted to do the wrong thing and switch lanes without using them.

The center screen is larger this year, and we like the fact that it allows you to keep the map displayed on the right third of the screen, regardless of what's shown in the primary portion. The navigation system also comes with an 80-gigabyte hard drive this year, 15 gigs of which can be used to store music files.

In the M model, drivers can also control the M Drive settings through the iDrive system. Chose the settings for the Electronic Damper Control, Dynamic Stability Control, Power (throttle mapping and transmission shift points), and Head-up Display in various iDrive screens and they will all be used when you press the M button on the steering wheel. These controls allow you to firm up the suspension, leave more room for play in the stability control system, increase throttle response, adjust shift points and add a rev counter warning in the optional Head-up display to inform you when to shift manually if you're using the automatic transmission's M (manual) mode.

Measured by its ergonomic packaging, the X5 is very good. Forward visibility is excellent; armrest height and window-switch placement are just as we like them. Everything, including the mirrors, can be adjusted with the driver in the driving position, meaning back against the seat rather than leaned forward to reach a switch or the rearview. The switches generally have a nice, precise feel.

Our only gripe with the packaging relates to the fat rear roof pillars. They limit visibility just behind the vehicle, and demand an extra dose of caution when the X5 is backing up. The available rearview camera helps, and we recommend it, though we found the camera is slow to turn off once you've started forward again. For 2010, BMW adds a Top View display to the rearview camera. The top view allows you to see the sides of the vehicle when backing up, making it easier to parallel park. In this case, more information is more helpful and not distracting.

The center console is wide, almost massive. Besides the iDrive controls, it sprouts BMW's video-game-style, electronic gear selector and a hand brake. A sliding plastic blind exposes an ashtray and the cupholders. Those cupholders aren't terribly deep, though they do have little tension devices that snug around the bottom of a cup. The console box opens down the middle, clamshell style, and it measures about six-by-six-by-ten inches, lined with a rubber mat. Its houses a power point, headphone-type auxiliary jack and the new USB port.

Storage options inside the X5 are fair: Much better than the typical European vehicle a few years ago, but not up to the best in this class. The glovebox opens with a remote switch in the center stack, closer to the driver, and it's large enough to hold small items beyond the extra-thick portfolio for owner's documents. The door bins are molded into the door panels, and split into two compartments. They're wide and deep, so anything you put here is likely to stay when you open or slam the door, and lined with rubber so contents aren't prone to sliding and making noise.

When BMW stretched the X5 seven inches (starting with the 2007 models), it did wonders for rear passenger room. Space is now competitive with the roomiest mid-sized luxury SUVs. A five-foot, nine-inch rear passenger has inches of headroom to spare, and enough legroom to stretch feet up under the front seat (assuming the driver is six feet or less). There's a reasonable array of accoutrements for rear passengers, too, including vents, a power point and small storage bin on the back of the center console. There's also temperature control and a fan switch on models so equipped. The dropdown center rear armrest offers no cupholders or storage, but it reveals the optional locking pass-through port for long items such as skis or fly rods.

Cargo space still ranks at or near the bottom of the class. There is nearly 22 cubic feet for stuff behind the second seat: somewhat larger than the trunk in a large sedan, though the space is tipped up on its end, with a much smaller load floor. Adding the optional third-row seat expands passenger capacity to seven, but it also eliminates most of that cargo space. BMW claims adults up to five-feet, four-inches tall will be comfortable in the third row, though we can't verify that from experience.

A standard cargo blind opens and retracts over the carpeted area behind the second seat, which features several tie-down points and a rail system that accommodates slide-out accessories offered by BMW dealers. The rear seat backs fold forward easily, but not completely flat, so there a slight change in the angle of the load floor created. The bottom cushion for the rear seats can be removed completely, as a single piece. That levels the load floor, but then you have to find a place for the seat bottom.

Even with cargo space maximized, the X5 offers less capacity than most competitors. With 75.2 cubic feet available, the X5 is surpassed by the Acura MDX (83.5), the Volvo XC90 (93.2) and a host of others. There is some additional storage under the X5's load floor, enough for a tool kit or a six pack, in the bin with the temporary spare.
