2008 BMW X6 Buying Advice

The 2008 BMW X6 might have been the 2009 BMW X6 if not for a technicality. BMW began assembling X6s destined for customers in January 2008 – timing that could have allowed it to unveil its bold new “Sports Activity Coupe” as a 2009 model.

But a handful of pre-production X6s were assembled in December 2007. Under federal rules, that was a month too early for it to be introduced as an ’09 model. So the X6 rolled into showrooms in April 2008 as an ‘08.

No big deal, really. But it is symbolic of a vehicle that in many ways seems neither here nor there.

Here the BMW X6 is an SUV. There it’s a coupe. Here it’s a cargo-hauling hatchback. There it’s a hunkered-down four-seater. Here it has off-road ride height and all-wheel drive. There it’s honed for highway handling. Here the BMW X6 is a great idea. There it’s a machine that spreads its talent a little too thin.

What is clear is that the X6 is on the automotive cutting-edge. Is it conventionally good looking? Does its particular blend of virtues translate into value? The answers are immaterial to its audience of upscale early adopters. However, they will be pleased to know their needs will be nicely met by the less-expensive of the two X6 models.

That would be the X6 xDrive35i, which is plenty fast with its 300-horsepower six-cylinder engine and pricey enough at around $54,000 to guarantee look-at-me exclusivity.

The xDrive50i, which has a 400-horsepower V-8 and a starting price around $64,000, doesn’t present enough advantage over the xDrive35i in everyday driving to justify its extra cost. It doesn’t look significantly different, either. BMW expects only 30 percent of X6 buyers to opt for the V-8 version.

BMW coins the term Sports Activity Coupe to describe the X6, which it pitches as a cross between its midsize X5 SUV and its big, expensive 6-Series coupe.

The X6 does have some things in common with the squared-off seven-seat X5, including certain cabin, suspension, and chassis components. It also has the same 115.5-inch wheelbase (distance between front and rear axles). And although the X6’s body is about an inch longer than the X5’s, the X6’s roofline is a significant 3-inches lower. That radically tapered roofline with its short side glass rests upon a brawny, high-wasted body with an SUV-worthy ground clearance of 8.35 inches.

But this is no off-road wagon. There’s no low-range gearing, for example, and no ride-height adjustment. Instead, the X6 summons an arsenal of technology in the service of high-performance on-road driving.

2008 BMW X6 Changes back to top

The X6 xDrive35i model has the same twin-turbocharged 3.0-liter inline six-cylinder engine found in BMW’s 1-Series and 3-Series cars. The X6 xDrive50i has a twin-turbo 4.4-liter V-8 that’s not used by any other BMW. A six-speed automatic with steering-column paddle shifters is the sole transmission.

Power flows constantly to all four wheels, normally at a 60-percent rear bias to mimic the sporty handling characteristics of a rear-wheel-drive vehicle. Like BMW’s X5 and compact X3 SUVs, the X6 comes with the company’s xDrive system, which automatically redistributes power front to rear to provide the best grip.

The X6, however, introduces BMW’s Dynamic Performance Control, a system designed to further enhance handling and stability by automatically multiplying torque to an individual rear wheel. It employs sensors to monitor the X6’s behavior in fast changes of direction and distributes power between left and right rear wheels to counteract nose plow or fishtailing. BMW says it’s the first such system that delivers power an individual rear wheel even if the driver is not applying the throttle. An instrument-cluster pictogram displays how much power is going to any of the X6’s four wheels at any given time.

Optional is an adaptive suspension that automatically counteracts body lean and pitch as the X6 turns, accelerates, or stops. It also adjusts ride firmness automatically or within sport or comfort modes as chosen by the driver via a consol button. Also optional is BMW’s Active Steering, which at low speeds enables the vehicle to change direction with fewer turns of the steering wheel.

Standard are antilock brakes and an antiskid system that automatically applies individual brakes to keep the vehicle on course in a turn. Also included is Trailer Stability Control to counteract sway and drift when towing, hill descent control to limit vehicle speed down steep slopes, and systems that automatically maximize brake pressure in the interest of minimum stopping distances. X6s come with low-profile 19-inch tires on alloy wheels; 20-inch wheels and tires are optional.

Visually distinguishing the xDrive50i from the xDrive35i are different numerals in the small fender badges, black instead of silver fins in the twin-kidney grille, and rectangular instead of round exhaust tips.

There’s no difference inside. Both X6 models have two front and two rear bucket seats, each divided by a center storage console. The rear seatbacks fold individually to form a flat cargo floor. Leather upholstery and brushed-aluminum accents are standard, as is a choice of two wood trims. Also included is BMW’s controversial iDrive central control for navigation, climate, audio, and communications.

The 2008 BMW X6 xDrive35i and xDrive50i will carry over unchanged for 2009, but BMW is likely to add a gas-electric hybrid model to the 2009 line. The X6 hybrid will team a V-8 engine with a special transmission that incorporates two electric motors. It’s similar to the system used in General Motors’ full-size SUVs, but BMW’s goal is not so much improved fuel economy. Rather, it’ll use the electric motors to furnish additional performance. The system is self-charging, with no plug-in required.

The BMX X6 isn’t likely to get major alterations to styling or technology for five years or so.

2008 BMW X6 Test Drive back to top

Driving the BMW X6
BMW summons lots of technology in the service of making a heavy wagon with a high center of gravity imitate the exemplary behavior of a BMW car. It’s only partly successful.

Little fault lies with the engines or transmission. BMW’s quote of 6.5 seconds 0-60 mph for the xDrive35i isn’t particularly impressive, but the more-meaningful measure is the smooth six-cylinder’s ability to deliver gratifying throttle response in most any situation. The V-8 xDrive50i is faster -- 0-60 in 5.3 seconds, says BMW – but everyday driving seldom presents the opportunity to tap into its extra muscle.

With either engine, gear changes are unobtrusive with the transmission set in Drive and obedient when manipulated with the paddle shifters. Set in Sport mode this six-speed acts like the smartest guy in the room, automatically choosing gears precisely even in erratic traffic and holding the right ratios to help you storm into and out of corners on curvy roads.

That the ride/handling balance should be so good. Even with every suspension gizmo sensing and evaluating and whirring into action, the X6 can’t summon that silky passage over bumps and through turns its BMW breeding and coupe profile promise.

It’s more than competent, certainly, especially for a vehicle with SUV genes. Steering is direct and meaty – maybe too firm in around-town driving. The X6 is balanced in sweeping turns, and big brakes stop it short and sure.

But it also occasionally feints and shudders over bumps instead of soaking them up and continuing on. It’s got a tall-in-the-saddle list in fast turns, and a reluctance to really bite into sharp corners, even with a Sport package and the 20-inch tires. These are failings forgiven the X5 because it’s an SUV, but they’re inconsistent with the higher aspirations of the X6.

Riding in the BMW X6
There’s no escaping the firmness in the X6’s suspension, but to take the brittleness out of traversing sharp ridges and prominent tar strips, try sticking with the 19-inch wheels and tires; they shouldn’t generate as much road noise over coarse surfaces as the 20s, either. X6 occupants won’t detect much wind rush even at highway speeds. The engines are difficult to hear at anything less than three-quarters throttle; after that, the six-cylinder emits a high-tech whine and the V-8 a NASCAR-worthy exhaust bellow. It’s exciting.

High ground clearance and a low roofline conspire to make getting into the X6 a tiresome climb-and-crouch exercise; narrow rear-door openings don’t help.

Front-seat room, comfort, and support is terrific, and the driver gets an appropriately elevated view of the road ahead and surprisingly useful vision aft, despite the narrowing effect of the rear window’s slant.

In back, the buckets-with-console setup creates a sense of occasion for passengers, but the seats are set low to maximize headroom, so the view they get is mostly of the front seatbacks. The rear backrests don’t adjust for angle -- a demerit in this price class. The rear foot wells aren’t cramped, but those longer of leg will find themselves in a bit of a knees-up posture.

A rigid cargo cover snaps in place to close off the luggage bay, lessening the impression that you’re in a traditional hatchback or wagon. And BMW’s correct when it says the X6 has far more cargo room than a traditional coupe. There’s a usable 20 square feet with the rear seatbacks up, 51 with both folded. Still, every competitor mentioned above has at least 10 square feet more cargo space. And a 3-inch tall lip along the lower edge of the X6’s cargo opening means you can’t simply slide heavy objects in or out.

The big hatch itself is nicely counterbalanced to open and close easily. Huge map pockets in all four doors and plenty of smaller bins make for good in-cabin storage.
Inside and out, the X6 feels sturdy and carefully constructed of quality materials.

BMW X6 dashboard and controls
Instruments are circular and meticulously marked. Controls are easily reached and activate with smooth, short movements. A medley of pleasing surface shapes creates an atmosphere that rings with modern sophistication.

Quibbles include a steering-wheel rim that may be too thick for smaller hands to hold comfortably. And if the paddle shifters are there to promote rapid, intuitive gear changes, why are they shaped to require use of the thumb for upshifts and then a repositioning of the hand to use the fingertips for downshifts?

No quibbling about the iDrive system. It complicates simple functions like setting radio stations and frustrates already-complex ones, such as programming the navigation system. The driver pushes, twists, and tilts the central control knob, burrowing through layers of programming, watching the dashboard screen for the hoped-for result. Working iDrive becomes easier in time, of course, but it can confound even the practiced user.

It’ll also take some getting used to the transmission lever, which is really a joystick control that toggles back to its start position no matter what gear you shift into. Shifting into park, however, is via an anomalous button atop the lever. You have to scan the gear-indicator readouts to be certain you’re in the desired setting. A couple of innovations do prove useful. Auto Hold eliminates “idle creep” so you don’t have to keep your foot on the brake at stoplights. And if you shut off the engine with the transmission in Drive, the X6 automatically shifts into Park.

2008 BMW X6 Prices back to top

The 2008 BMW X6 xDrive35i starts at $53,275, the X6 xDrive50i at $63,775. Both prices include destination fees.

Equipment differences include a navigation system, which is standard on the X6 50i and a $1,900 option on the X6 35i. The system includes voice activation and a back-up camera that displays on the navigation screen a view of what’s behind when the transmission is shifted into reverse.

Options on both models include BMW’s Active Steering system ($1,400), a rear-seat DVD entertainment ($1,700), and power operation for the cargo liftgate ($500). The optional head-up instrument display ($1,200) projects vehicle speed, navigation directions and other date onto the windshield in the driver’s line of sight.

Also available are Sport packages tailored to each model. They start around $3,600 on the xDrive35i and around $3,100 on the xDrive50i. The sport packages include a choice of alternate wheels styles and performance-tread tires, the adaptive suspension system, darkened “Shadowline” exterior trim, and a revised limiter that increases top speed of the 35i to 150 mph from 130 and top speed of the 50i to 155 mph from 130.

No indication yet about the pricing of the 2009 BMX X6 hybrid model.

2008 BMW X6 Fuel Economy back to top

EPA fuel-economy estimates for the xDrive 35i are 15 mpg city, 20 highway. EPA estimates for the xDrive50i are 13 mpg city, 19 mpg highway. Both engines required premium-octane gas.

2008 BMW X6 Safety and Reliability back to top

In addition to its passel of active-safety features, such as antiskid control, the X6 has head-protecting curtain side airbags designed to deploy in both a side collision and when sensors detect an impending rollover. To warn following drivers of quick deceleration, the X6 comes with BMW’s two-stage brake lights, which illuminate with greater intensity in emergency stops.

The federal government has not published results of any collision tests on the X6, but the BMW X5 gets uniformly strong ratings in tests of driver and passenger protection in crashes and scores well for rollover resistance.

Surveys by J.D. Power and Associates the leading automotive consumer satisfaction-measuring firm, show BMW as a brand rates above average in dependability and also for the purchase and sales experience.

For overall quality, the BMW brand rates average in J.D. Power surveys. It gets above-average grades for mechanical quality and body and interior quality, but subpar marks for the design of the interior, features, and accessories.

The X6 is too new to be included in the surveys. However, it’s built alongside the X5 at BMW’s plant in South Carolina, and J.D. Power surveys rate the X5 average in overall dependability. The X5 has not scored well in J.D. Power surveys of initial vehicle quality, ranked by owners as below average overall.

2008 BMW X6 Release Date back to top

The 2008 BMW X6 xDrive35i went on sale in April, the 2008 xDrive50i is slated to go on sale during the summer of 2008. Release date for the 2009 BMW X6 models is November 2008.

2008 BMW X6 Competition back to top

Four other premium-priced performance-oriented SUVs are prime competition for the 2009 BMW X6: the Infiniti FX, Land Rover Range Rover Sport, Mercedes-Benz M-Class, and Porsche Cayenne. They have similar exterior dimensions to the BMW X6, but seat five instead of four and have more cargo volume.

The 2009 Infiniti FX is the only SUV in this bunch from a Japanese brand and also is the least expensive. The 2009 FX introduces the second-generation version of this boldly styled wagon and boasts lots of tech tricks, including Infiniti’s Around View Monitor, designed to aid parking by projecting on a dashboard screen a 360-degree depiction of the exterior surroundings. The 303-horsepower V-6 FX35 is likely to start around $40,000, the 390-horsepower V-8 FX50 at just over $50,000. The 2009 FX design won’t change for five years or so.

The Land Rover Range Rover Sport debuted as a 2006 model and probably won’t change significantly until the 2010 model year, when it will likely get a restyle instead of a full redesign. This SUV has been a hit for Range Rover, bringing a dash of brio to the brand’s staid British character. The Range Rover Sport starts around $58,000 for the 300-horsepower HSE version and around $72,000 for the 390-horsepower Supercharged model.

The current edition of the Mercedes-Benz M-Class launched as a 2006 model and was freshened for 2008 but won’t be redesigned until at least model-year 2011. This is the most conservative-looking X6 rival, and the most comfortable, too. But it packs plenty of punch in the 382-horsepower ML550 (starting around $53,000) and in the 503-horsepower ML63 (starting around $87,000).

Introduced for 2003, the Porsche Cayenne is perhaps the X6’s most-direct competitor for performance and personality. The rivalry should ratchet up for the 2010 model year when the next-generation Cayenne is due to arrive with a new shape and proportions not far afield from the X6’s. The current 385-horsepower Cayenne S model starts around $58,000, the 405-horsepower GTS around $70,000, the 500-horsepower Turbo around $94,000.
