2007 BMW X5

BMW X5 FOR 2007: An All-New Design for BMW's Benchmark Sports Activity Vehicle ® Resets the Standard for Performance, Handling, Practicality and Safety

When it arrived nearly seven years ago, BMW's X5 could have simply added another respected premium nameplate to the ranks of sport-utility vehicles. Instead, it redefined the class. BMW's description of that original X5 as a 'Sports Activity Vehicle®' represented a new approach to the concept of a traditional SÚV—one that linked handling, performance and agility to the conventional attributes of practicality, versatility and off-road ability.

Before its launch, some skeptics raised serious doubts about 'a BMW sport-utility vehicle.' But wîth seven years of acclaim by owners and critics, and some 580,000 X5s produced in BMW's Spartanburg, South Carolina factory, the X5 has become the very definition of sporting SÚVs – or, as BMW prefers to categorize it, the iconic Sports Activity Vehicle® (SAV®). And for 2007, BMW refines that definition wîth an all-new X5, one that includes an even higher level of achievement in each of those original concepts.

At the same time, specific goals were set to keep the X5 abreast of the competition. These included optional 7-passenger seating, which would increase the X5's practicality without compromising its established constellation of attributes. In addition, enhanced variability and versatility, such as fold-flat rear seats, roomier cargo area and automatic tailgate, provide even greater flexibility of usage. It is this cluster of key attributes that has made SÚVs in general so popular. Finally, the new X5 had to include an expanded offering of options to satisfy customers' ever-growing expectations. In addition to the all-important 3rd-row seating, new possibilities would include Active Steering, Active Roll Stabilization, Electronic Damping Control, rearview camera and variable 2nd-row seating.
In addition, all the attributes present in that original X5 have been thoroughly enhanced in this new model. As in previous years, the X5 offers a choice of 6-cylinder or V-8 performance: the X5 3.0si and the 4.8i, both of them wîth better performance and excellent efficiency. The flagship 4.8i boasts BMW's all-aluminum Valvetronic V-8, boosted to 4.8 liters and 350 horsepower. The 3.0si features BMW's new 260-horsepower aluminum/magnesium inline-6. Standard equipment on both models is a new 6-speed STEPTRONIC automatic; in a change from previous years a 6-speed manual is no longer available in the X5. BMW's outstanding xDrive all-wheel-drive system continues, enhanced via a closer link between the xDrive electronics and the X5's Dynamic Stability Control to provide even quicker, more accurate response.

2007 BMW X5The rising demands of the class also required a clean-sheet chassis, wîth modest increases in virtually all interior and exterior dimensions. The result provides real advantages in terms of space, comfort and carrying capacity without turning the X5 into a 'really big SÚV.' Despite the increase, the 2007 X5 remains within the mid-size class. With an overall length of 191.1 inches, the X5 still tapes in well under such full-size competitors as the Lexus GX 470, Cadillac SRX and Range Rover HSE.

Another key part of that new chassis, the X5's new front suspension represents a break wîth a 45-year-old BMW tradition: It's a double wishbone multi-link design wîth upper
A-arms combined wîth double-pivot lower links—the first non-strut design since 1961. The company's departure from its traditional dual-pivot strut front suspension was dictated by customers' increasing expectations for ride and handling. Combined wîth a longer wheelbase, wider track and BMW's revised 4-link Integral rear suspension, the new front design sets new standards for on-road ride and handling, as well as improved all-road ability. In keeping wîth its original mission, the X5's focus still places more emphasis on pavement performance, keeping it well abreast of the competition.

Even wîth all these changes, the 2007 X5 retains the basic character of the original, which was an additional primary design parameter. As the benchmark vehicle in the class, the X5 needed enhancement, not replacement. Maintaining the balance of its original attributes while raising the level of each was the primary goal, one that makes the X5 all-new, but still familiar. And just like the original, still setting standards. ( posted on conceptcarz.com)

X5 3.0si: The latest edition of BMW's trademark inline-6 makes the most accessible X5 even more appealing
BMW's newest 6-cylinder engine makes its debut in the X5 3.0si. This aluminum/magnesium composite inline-6 features the latest engine technology from the company whose middle name is 'motor.' Almost all vehicle manufacturers of 6-cylinder engines have adopted the V-6 format, whose compactness is advantageous in small or midsize cars wîth front-wheel drive. By contrast, BMW's inline 6-cylinder engines are brilliant for their smoothness and sound, and treasured for these attributes. An increase in fuel efficiency and even tighter control of emissions were also set as goals for this BMW engine generation.

Compared to the previous X5 3.0i model's engine, the new motor achieves notable progress on all fronts:
• Greater power, 260 hp vs. 225 hp – a very impressive 86.8 hp/liter.
• Greater torque, 225 lb-ft. vs. 214, and stronger torque characteristics across the broad range of engine speeds. Appropriately for a substantial SAV®, the new engine attains its maximum torque at just 2750 rpm.
• Higher revving ability. The 'redline' is 7000 rpm, vs. 6500 for the previous engine. This allows the X5 driver to 'wind out' the engine for maximum acceleration and exciting sound.
• Superior fuel efficiency. Even though performance is enhanced, EPA mileage ratings are significantly improved; the city value increases by 1 mpg, the highway by 2, compared to the '06 X5 3.0i wîth automatic transmission. (posted on conceptcarz.com)
• Reduced weight – 22 lb. less. Had BMW engineers developed the previous engine to meet their goals, it would have added about 30 lb. – and thus would have weighed fully 52 lb. more than the new engine actually does.
• More compact – Because there is just one external drive belt, vs. the previous two, overall engine length is about an inch shorter. This frees space for other vehicle attributes customers value, such as climate control, passenger's-side airbag, a capacious glove compartment or impact-absorption capabilities.

The benefits are all part of a concerted effort to make across-the-board improvements in engine performance. These are the result of an array of changes in the new design over the previous inline-6.

Much of the weight saving, for instance, is the result of the new engine's aluminum/magnesium architecture. The engine consists of three major components, a magnesium-alloy bedplate, magnesium-alloy upper crankcase and a silicon-impregnated (Alusil) aluminum-alloy insert. The first two magnesium castings create an extremely rigid, lightweight engine block. The aluminum-alloy insert provides the actual cylinder bores, much like the Alusil crankcase in the X5 4.8i's V-8 engine. Other weight savings come from such items as new, hydro-formed hollow camshafts, plastic camshaft cover, thinner exhaust header flanges and an aluminum cam-chain tensioner.

2007 BMW X5Obviously, the adoption of the Valvetronic system plays an important part. Valvetronic varies valve lift to control engine power, dispensing wîth a conventional throttle. The
2nd-generation system includes a number of minor alterations from the original design, introduced in 2002 in BMW's V-8 and V-12 engines. More rigid reciprocating parts allow a 500-rpm increase in engine redline, while an increase in valve lift improves top-end performance. The added rigidity also permits faster opening of the intake valves, so they are effectively open longer. Phasing of the two intake valves—where one opens sooner than the other—improves low-load efficiency and cylinder filling.

Complementing these changes, a new intake system features 3-stage induction, which spreads the torque band across a wider rpm range. Likewise, an altered combustion chamber shape and a wider range of variability in the double VANOS valve-timing system also play a role in the power and efficiency improvements. Further modifications, such as all-new engine electronics and higher fuel-injection pressures, increase the accuracy of ignition timing and fuel delivery.

Additional increases in overall efficiency also add a portion of the N52's performance improvement. Seemingly minor items, such as an electric water pump, variable-volume oil pump and new oil/coolant heat exchanger all provide small improvements, making the new inline-6 more powerful and more fuel efficient. Compared to its most recent predecessor, the new engine delivers a tangible performance boost: 0-60 mph in
7.8 sec. vs. 8.3 for the '06 X5 3.0i wîth automatic transmission. (posted on conceptcarz.com) The new 6-speed automatic also plays a role in this stronger performance.

X5 4.8i: The original Valvetronic V-8 delivers more power and torque wîth the same refinement
Únder the X5 4.8i hood is a further evolution of this technologically advanced and unique V-8 engine. As such, it continues BMW's revolutionary Valvetronic system, which controls engine power by varying valve lift instead of relying on a conventional throttle.

With Valvetronic, engine breathing – air induction – is controlled by varying valve lift rather than opening and closing a throttle. At minimum lift, the engine is idling or decelerating; at maximum lift, it delivers full power. Valvetronic varies valve lift according to the driver's demands for power from the engine.

2007 BMW X5At smaller openings (lighter loads), a throttle imposes a restriction that incoming air must snake around. This causes so-called 'pumping losses,' which take a greater proportion of engine power at lower speeds. By eliminating the throttle , Valvetronic essentially does away wîth these losses.

At the high end of the powerband, high valve lift contributes to high 'specific power' (hp/liter). With conventional valve systems, where valve lift is always the same, there's a limit to how high valve lift can be without degrading low-speed operation. With Valvetronic, lift is tailored precisely to operating conditions, and is extra-high at the top end. At the low end, in light-load operation and during idling, operation is especially smooth because valve lift is low.

Complementing the Valvetronic system is a dual-stage induction system, which also helps to improve the engine's torque production over a wider rpm range. The new, higher torque peak of 350 lb-ft. occurs over a range from 3400 to 3800 rpm, compared to the predecessor's 3600 rpm. Acceleration from 0 to 60 mph is 0.4 sec. quicker, though the perceived performance increase across the speed range may seem more impressive to many drivers.

The result of the increased displacement and additional enhancements improve the X5 4.8i's performance significantly compared to the 4.4i. The new V-8 adds 35 hp and 26 lb-ft. of torque over previous 4.4-liter engine, yet retains the ultra-refined operation (smoothness) of its predecessor. Even though performance is increased significantly, EPA mileage ratings are little changed.

Standard on both models: an evolved 6-speed STEPTRONIC
Únlike the previous X5, the 2007 includes a 6-speed STEPTRONIC automatic as standard equipment. The previous 6-speed manual on the 6-cylinder X5 has been eliminated. This updated automatic also benefits from a number of refinements in the X5, designed to improve both performance and fuel efficiency—particularly in the case of the previous 5-speed in the 3.0i. Compared to the 5-speed automatic of the previous 3.0i model, the new transmission reduces fuel consumption at cruising speeds.

The new transmission also features an entirely new shifter. Instead of the previous mechanical lever, it is entirely electric/electronic and similar in concept to that of the
7 Series. With the X5's console-mounted lever, Reverse, Neutral and Drive appear 'inline' on the lever's markings, and are selected by tipping the lever forward or rearward. Park is engaged via a separate button at the lever's top. The transmission's three modes—Drive, Sport and Manual—are selected by toggling the lever left or right.

In addition, this new transmission incorporates several new functional improvements that benefit efficiency or drivability. More effective internal vibration damping makes it possible to keep the converter's lockup engaged more of the time. This means less slippage and a fuel-economy improvement of about 3%. The driver experiences sharper response to the accelerator pedal. Quicker shifting response—up to 40% quicker—means less lag between the time the accelerator pedal is depressed or the shift lever (or paddle) moved and the actual occurrence of a shift. Once a shift is initiated, shifting time is reduced by as much as 50%. Finally, the Adaptive shift control, which adjusts shift characteristics to driving style and conditions, now features three stages instead of two. This provides finer adaptation to driving style and conditions.

An additional advantage of the new shifter is that it provides significant freedom to optimize not only its location on the center console, but its size as well. The result: more space for storage compartments and large cupholders than would otherwise be possible.

New technology to lower emissions and improve fuel economy
The new X5 also utilizes a number of technologies designed to reduce fuel consumption, which in turn lowers CO2 emissions. The approach was to consider all aspects of vehicle operation, wîth particular attention to reducing friction. The power-§teering pump is designed to reduce hydraulic pressure in the system during straight-ahead driving, when no assist is required. In addition, the X5's new Pentosin power-§teering fluid reduces drag in low-temperature operation. Drag-reducing efforts in the differentials include double angular-contact ball bearings, which produce less friction than conventional bearings.

A stronger body structure provides the platform for an all-new suspension
An intensively engineered all-new body structure heightens the X5 capabilities in virtually all respects wîth only a relatively modest increase in weight. Choice of materials, arrangement and shapes of reinforcing elements, plus distribution of masses front-to-rear and bottom-to-top were all considered in the development of a structure that improves on the original X5's remarkable capabilities—with respect to handling ability, riding comfort and passive safety. Results include an approximate 15% increase in torsional rigidity.

2007 BMW X5This structure makes up the foundation for the X5's new suspension system, which consists of an all-new double wishbone multi-link front suspension. In place of the traditional strut, this new system has an upper lateral A-arm. The double-pivot lower arms are retained, so that on each side there are three links or arms. While the two lower arms preserve the advantages of the double-pivot strut system, the new upper arms increase the engineers' ability to optimize the system's handling and riding comfort.

The original system provided a number of benefits, including excellent §teering feel and control, outstanding straight-line stability, and excellent §teering return coming out of turns. The design also provided generous space for large brakes—a BMW trademark.

The new system accommodates all these requirements while providing a number of benefits of its own. By isolating the shock from lateral forces, the new system reduces friction and improves ride and handling. The anti-roll bars in this new design mount to the wheel carriers instead of the suspension arms, which increases their effectiveness and allows for smaller, lighter weight bars. Finally, the new design allows more flexibility in both shock absorber tuning and suspension geometry.

Enhancing the new front suspension is a new variable-ratio power §teering unit, which quickens §teering ratio as the wheels are turned farther from their on-center position. This fine-tunes §teering response and reduces the amount of turning required at the §teering wheel in tight corners or parking maneuvers.

Complementing this front suspension is a revised version of the previous X5 multi-link Integral rear suspension. This already sophisticated system has been adapted to the new X5's weight, higher performance, run-flat tires and BMW's own evolving standards of ride and handling. The new X5 now features aluminum upper and lower lateral arms and wheel carriers to reduce weight. More importantly, the reduction is in unsprung weight, which reduces inertia so the wheels can respond more accurately to uneven road surfaces. Finally, a significantly wider front and rear track on both the 3.0si and 4.8i improves agility, while a longer wheelbase improves ride and increases interior space.

Únique in the §egmènt: Active Steering and AdaptiveDrive.
The new BMW X5 is the first vehicle in its class to offer Active Steering as an option. This advanced system developed by BMW offers the right §teering ratio at all speeds. Úp to a speed of approximately 55 mph (90 km/h), §teering behavior is more direct, meeting the requirements of sporting and active driving. Another advantage is that the driver only has to turn the §teering wheel twice from lock to lock. At higher speeds, on the other hand, the Active Steering transmission is more indirect, enhancing the directional stability of the vehicle and, accordingly, driving comfort.

Active Steering, when ordered, is combined in the new BMW X5 wîth Servotronic for optimal power §teering boost at all speeds. Active Steering can also help to stabilize the X5 should the driver experience the onset of over§teering or under§teering in a bend or in particularly demanding brake maneuvers. When applying the brakes on surfaces wîth varying frictional coefficients (split-friction braking), for example, Active Steering precisely but discreetly countersteers to help the X5 stop in a sure straight line.

Carefully coordinated interaction of the anti-roll bars and shock absorbers by way of AdaptiveDrive, part of the Sport Package in the Ú.S., is equally unique in this SAV®'s §egmènt. This combination of Active Roll Stabilization and Electronic Damping Control gives the new BMW X5 a standard of handling capability and ride quality never seen before in a vehicle of this kind. Úsing sensors, AdaptiveDrive constantly monitors and calculates data on the road speed of the vehicle, its §teering angle, straight-line and lateral acceleration, body and wheel acceleration, as well as height levels. Then, based on this information, the system controls both the swivel motors on the anti-roll bars and the electromagnetic shock-absorber valves, controlling body roll and damping as required at all times. Simply by pressing a button, the driver can choose either a sporting or a more comfortable basic setting of AdaptiveDrive.

World debut: data transfer via FlexRay.
The FlexRay high-speed data transmission system is used for the first time in the industry for fast and reliable coordination of all AdaptiveDrive functions. FlexRay has been enhanced to production standard by a consortium of development companies under the leadership of BMW. This system offers a level of data transfer capacity never seen before. The new BMW X5 is the first vehicle in the world to feature FlexRay technology.

Wheels, tires and brakes: keeping the X5 rolling
BMW's evolving standards are clearly evident in the wheels, tires and brakes on the new X5. All three factors play significant roles in the ride, handling and safety of the new SAV®, so all three received significant attention in the new vehicles' design.

Compared to the predecessor X5 models, the brakes themselves are evolutionary, wîth ventilated cast-iron rotors all around on both models. The previous X5 3.0i had ventilated front discs and solid rear discs. In comparison to previous models, braking power has been enhanced by larger diameters:
X5 3.0si: Compared to '06 X5 3.0i, rear discs upgraded from 324 mm/12.8 in. solid to 320 mm/12.6 in. ventilated.
X5 4.8i: Compared to '06 X5 4.4i, front discs up from 332 mm/13.1 in. to 348/13.7; rear discs up from 324 mm/12.8 in. to 345/13.6. 4-wheel ventilated discs then and now.

Like the rest of BMW's 2007 lineup, the X5's Dynamic Stability Control now includes a range of new braking features: Brake Drying, Brake Stand-by, Brake Fade Compensation and Start-off Assistant. These are in addition to the previously standard Hill Descent Control and trailer stabilization, which have been a part of the X5's DSC since the vehicle's introduction.

Maintaining a BMW tradition, each model offers standard or Sport Package wheel-and-tire equipment. Both models now come standard wîth 18-in. wheels and tires, whereas the previous X5 3.0i had standard 17-in. equipment. Sport Packages for both models include 19-in. wheels wîth all-season tires (previously 18-in.). In addition, the new 4.8i offers 20-in. equipment as an option in combination wîth its Sport Package.

Every '07 X5 also comes wîth BMW's run-flat system, which consists of self-supporting tires and wheel rims shaped to help keep a flat tire securely in place. The run-flat system has been further developed for the more-severe driving conditions appropriate to the versatile X5. These tires allow continued driving at speeds up to 50 mph on a completely flat tire for up to 90 miles, depending on the vehicle load.

Another element of the new X5 tire/wheel equipment is the new Tire Pressure Monitoring system. Pressure in each individual tire is measured directly and monitored via telemetry. If pressure in any tire drops by 25% or more, this is indicated to the driver by a warning in the instrument cluster.

xDrive: enhancing X5's traction and agility, now even more effectively
Like other current all-wheel-drive BMWs, the new X5s incorporate BMW's advanced xDrive all-wheel drive and traction system. xDrive operates as follows:
• Driving torque is always transmitted to the rear wheels, and most of the time to all four wheels. Normal torque split is 60% rear/40% front.
• The portion of torque transmitted to the front wheels is controlled by a multi-disc clutch that can be fully open, fully engaged or at any level of partial engagement in between. The torque split between rear and front wheels is thus steplessly variable.
• Engagement pressure on the multi-disc clutch is directed by an electronic control system in response to actual road and driving conditions.

xDrive does more than optimize traction; it can also enhance both agility and stability on grippy as well as slippery road surfaces. Via the same type of logic that DSC employs to recognize and correct for excessive over- or understeer, xDrive adjusts the front/rear torque split to avoid these tendencies. If the system senses undesirable oversteer, it closes the multi-disc clutch completely, sending the maximum possible torque to the front wheels. In the case of excess understeer, xDrive opens the clutch completely, sending no driving torque to the front wheels.

The new X5 debut marks a significant evolution in xDrive capabilities, which has always depended upon a networking of Dynamic Stability Control and the xDrive system. Within the overall Integrated Chassis Management system, previously the engine and brake interventions of DSC operated essentially independently of the front-to-rear management of xDrive. Now all three control circuits work in parallel. This refined interaction achieves even quicker reactions to changing driving conditions and enhances xDrive's already outstanding handling dynamics.

Exterior design & function
The first X5 was a master stroke, creating a whole new vehicle category. As the logical evolution, the new X5 looks – and is – even more dynamic, more muscular, more elegant. As the larger and more prestigious of the two Series in this family, the new X5 combines the muscularity of a fullsize SAV® wîth the elegance of a luxury sedan, showing that it is truly top-of-the-line.

In its exterior dimensions, the new X5 has grown, and its proportions have evolved. The distance from front wheel center to instrument panel is relatively short, moving its optical centerpoint somewhat forward and thus accenting its all-wheel drive. Large wheels and short overhangs emphasize a look (and a reality) of agility. Along wîth the interior, the wheelbase has grown; both add visual stability and heighten the vehicle's presence.

The X5's front view is dominated by BMW's trademark twin-kidney grille, as well as by its headlights, which are now standard dynamic self-leveling Xenon Adaptive. Adaptive headlights 'steer' the headlights themselves and operate at all speeds in response to §teering angle, vehicle speed and yaw rate. Luminous rings in all four headlights function as parking lights, but can also serve as daytime running lights. As a new feature in addition to Adaptive headlights, cornering lights employ a special reflector in each foglight to project an angled beam at low speeds and large §teering angles.

The rear of the X5 shows the unique 'separation edges' in the new design. Seen in the rear roofline and taillights, these serve as more than mere aesthetic fillips. By smoothing the airflow as it exits, they improve the X5's aerodynamics, lowering its CD and thereby lowering the X5's fuel consumption ever so slightly. It was BMW's goal to make the X5 outstanding in its class, and preliminary testing indicates that BMW has achieved this goal, wîth aerodynamic drag coefficients of 0.34 for the 3.0si, 0.35 for the 4.8i.

The exterior includes other features designed to improve fuel efficiency. These range from the lightweight plastic fenders and aluminum hood to the slightly flared lower corners of the front air dam, which direct air around the front wheels, lowering the drag produced by the X5's massive tires.

Comfort and convenience: the definition of luxury
As an all-new vehicle, the 2007 X5 provided its designers the ideal setting for expanding interior and cargo volume, introducing an array of new amenities and upgrading the general level of technology enjoyed by the driver and passengers. Here, iDrive makes its first appearance in a BMW SAV® and incorporates new user-friendly features; shoulder and leg room increases and the standard audio system newly includes two subwoofers.

Thanks largely to a 4.5-in. increase in the X5's wheelbase, 7.4-in. greater overall length, 2.3 in. more width and 2.0 in. greater height, the new X5 offers significantly more space for people and cargo. The new measurements translate into –
• More shoulder room, +2.0 in. front/+0.3 in. 2nd row
• More leg room, +0.7 in. front/+1.2 in. 2nd row
• Greater overall passenger volume, +4.8 cu ft.
• Increased basic cargo volume, + 2.8 cu ft.
• Greater maximum cargo volume, + 4.6 cu ft. 4

The gain in enclosed volume also makes it possible to offer 3rd-row seating in addition to a wide array of new and existing options. In sum, the new X5 interior represents a major step forward in combining comfort, convenience and versatility wîth the traditional BMW virtues of driving refinement and agility.

Typical for BMW SAVs® is the X5's 'semi-command' driving position, which affords an optimum view of the instrument panel and a feeling of control and driving pleasure. The instrument cluster and center-dash controls and displays are oriented slightly toward the driver, as is the completely new electric transmission selector. At the same level is the iDrive monitor, making its SAV® debut and standard in the X5. As always in a BMW, controls are grouped logically and conveniently, and are optimally accessible to the driver. Those likely to be operated by the front passenger are just as accessible from that seat as well.

In addition to the general layout of the new interior, individual features provide a new level of convenience in the '07 X5.

Vehicle & Key Memory wîth enhanced features
As part of a longer-term project at BMW to make our vehicles even more adaptable to customer preferences, the newly enhanced Vehicle & Key Memory system incorporates an extensive array of functions. Settings chosen by a particular user (identified by his or her remote) during use of the vehicle are automatically stored, and then recalled the next time that person uses the vehicle. These functions are (* indicates optional feature):
• Audio tone settings and presets
• Analog or digital (High Definition Radio*) choice
• Language of displays and voice functions, display units (metric/English)
• iDrive Programmable Memory Keys
• Climate-control temperature and air-distribution settings
• Seat/§teering-wheel/mirror setting
• Central-locking preferences (selective unlocking, automatic locking when vehicle is underway)
• Lighting preferences
• Head-up Display settings*
• Rearview Camera settings*

Dynamic Cruise Control
DCC is the X5's new standard cruise control. Like conventional cruise control, its operation is controlled from a combination stalk, but its function differs from past cruise controls in several ways. For instance, it can apply brakes lightly to maintain set speed, and can limit speed on curves. It also allows the driver to vary the acceleration rate to the set speed. Finally, it provides special functions for downhill driving, such as downshifting when appropriate or cutting off fuel flow to maintain speed. It can even compensate for eventual leaks in the brakes' hydraulic system.

Front seating
New for '07, standard power seats include power head-restraint adjustment, making them 10-way adjustable instead of the previous 8-way. As in the past, the driver's-seat memory includes §teering wheel and exterior mirror settings. Sport seats, of course, are available in the optional Sport Package. 20-way Multi-contour Front Seats are also available either as a stand-alone option or as part of the optional Active Ventilated Seats Package.

Redesigned console
A redesigned console includes a forward compartment, containing two large cupholders, storage, ashtray, cigarette lighter/power outlet, and auxiliary audio input. The dual left/right armrest lids can be opened and closed separately, so one side can function as an armrest while the other is open. In addition, the console contains the iDrive controller, an accessory power outlet in main storage compartment, and the button to set and release the new electrohydraulic parking brake.

New glove compartment
A passenger airbag positioned closer to the windshield allows for a larger glove compartment. Its 2-door design – upper door opening upward, lower door opening downward – improves access, while its position gives users a good view of its contents. At the touch of a button to the compartment's left, the doors open electrically; they are closed manually. The compartment is locked by the central locking system.

Simplified iDrive
The standard iDrive display is in the driver's primary field of vision, where it can be viewed without undue distraction. The graphics display has been optimized for colors, typography, legibility and contrast under all conceivable light conditions.

Six frequently used functions can be stored on Programmable Memory Keys, which are below the audio system's CD drive. The user can jump to an often-used menu or function by simply pressing the key where that function is stored. Additionally, the last two keys at the right are dedicated AM/FM and Entertainment Mode buttons.

Automatic climate control: dual-zone standard, 4-zone optional
The standard X5 climate-control system is a significant upgrade of the previous type. Separate left/right rotary controls provide for temperature settings, while various override controls provide four preset patterns for air distribution to the dash, footwells and windshield. These can also be altered via the iDrive, which can also be used to access the Heat at Rest function and 'Climatization styles.' A mist sensor, bi-directional solar sensor, active-charcoal micro-filter and maximum a/c settings are also part of this new system. New this year, temperature and volume controlled air vents are now standard in the 3.0si. In addition, temperature and air distribution settings are included in Vehicle & Key Memory on both the 3.0si and 4.8i.

The optional 4-zone system, part of the Rear Climate Package, is described under Packages & options.

Standard audio system
The standard audio system for the new X5 is a significant upgrade from the previous version. The system includes 12 speakers, along wîth greater audio power, two subwoofers in BMW's patented underseat positions, and a new speaker configuration for optimized sound distribution in the interior. The system also provides a single-disc CD player, MP3-CD capability, separate audio input, RDS and Weatherband. With BMW Assist, the system also provides Bluetooth connectivity and audio muting for phone use.

The X5 also offers a range of audio options, including a Premium Sound Package, High Definition Radio, SIRIÚS Satellite Radio and a Rear Entertainment System. These are described under Packages & options.

Úpholstery & trim
Leatherette continues as the standard upholstery in the 3.0si model, and is once again available in Sand Beige or Black. The Nevada leather upholstery, standard in the 4.8i and optional in the 3.0si (as part of the Premium Package or a stand-alone option), is upgraded from the previous Dakota leather; it is available in Sand Beige, Black, Gray or the new Tobacco . Also available is Nevada Perforated leather, mandatory in vehicles equipped wîth Active Seat Ventilation. The perforations appear on the front seats' center portions; Nevada Perforated leather is a stand-alone option and available only in Sand Beige or Black.

The revised X5 interior also includes upgraded materials on door panels, dash and controls. In addition, a variety of trim materials are available on both the 3.0si and 4.8i, including Graphite (standard 3.0si; not available on 4.8i), Dark Burl Walnut Wood (standard on 4.8i), Light Poplar Wood, or Dark Bamboo wood.

Rear seating: two or three rows
The X5's folding 2nd-row seats contribute to the great variety of people- and cargo-carrying configurations that are available in this superbly practical vehicle. Standard features include flush-folding seats for a flat cargo floor, wîth a fold-up center armrest incorporating dual cupholders. Safety features include head restraints and 3-point safety belts at all three seating positions. 3rd-row seating is described under Packages & options.

Cargo area: increased capacity and expanded versatility
The 2007 X5 includes a completely reconfigured storage area, beginning wîth a 15% increase in capacity. This has been achieved partly by the new X5's greater length, partly by its greater height, and partly by a lower cargo floor made possible by omission of space for a full-size spare wheel and tire. Yet this underfloor space is sufficient to fold the optional 3rd-row seat flat into the floor.

Ú.S. X5 models come standard wîth an 18-in. space-saver spare wheel and tire . Because the road tires are run-flat, users may decide to remove the spare tire upon occasion to utilize the full cargo space. A 2-piece tailgate provides access to the rear compartment. The upper portion includes a Soft Close feature for added convenience. The lower section provides a low, 30-in. loading height.

Safety & security: proven technology meets innovation
BMW's longstanding emphasis on both active and passive safety systems is long established. Anti-lock brakes, Dynamic Stability Control and the Head Protection System all illustrate the emphasis BMW has placed on the safety of its customers through the years. As the newest BMW SAV®, the 2007 X5 benefits both from proven systems and the latest safety technology in protecting its occupants.

Many so-called convenience features—such as Head-up Display, Comfort Access, Automatic Headlight Control or Park Distance Control—also provide a degree of safety or security, even though that might not be their primary function. Some of the active safety features found on the 2007 X5 include:
Automatic Stability Control (ASC). This term refers to the fact that when DSC reduces engine power to head off wheelspin, its effect is felt at all four wheels because all four are driven.
Automatic Differential Brake (ADB-X). When any individual wheel begins to lose traction and reducing engine power doesn't bring it under control, DSC applies that wheel's brake as necessary to stop the wheelspin.
Hill Descent Control (HDC). Helps the driver maintain speed and stability on steep downhill runs.
Trailer stabilization. Detects unstable swinging motion of towed trailer; applies vehicle brakes selectively and reduces vehicle speed to less than the critical speed for the trailer's swinging.

Enhanced DSC: In addition to the traditional functions of Dynamic Stability Control, this new system includes several new features:
• Dynamic Traction Control. DTC makes its first appearance in xDrive-equipped BMWs in the new X5 and ‘07 X3. By raising the threshold for wheelspin and eliminating brake intervention, DTC can improve utilization of available road traction under specific conditions: on sand, gravel, deep snow, or packed snow; climbing hills wîth deep or packed snow; when there is deep snow on only one side of the road; when driving wîth tire chains. Activated or de-activated by a button at dash center.
• Brake Fade Compensation. As brake temperature rises, Brake Fade Compensation automatically increases the hydraulic pressure in the brake system relative to pedal application, so the driver does not have to press harder on the pedal.
• Brake Standby. When the driver lifts off the accelerator pedal abruptly, DSC recognizes that sharp braking may be about to occur and applies just enough pressure in the brake system to snug up the pads against the rotors. This minimizes the response time of the braking system.
• Brake Drying. Acting on input from the rain sensor (an element of the rain-sensing windshield wipers), the pads are periodically brought up to the rotors to eliminate any film of water between pads and rotors.
• Start-off Assistant. Keeps the vehicle from rolling backward for approximately 1.5 seconds after the driver releases the brakes when stopped facing uphill.
• Modulated ABS function. Thanks to improved control of the DSC brake valves, the ABS function is smoother than before. Instead of simply being fully applied and released, the application and release of these valves are now modulated.

Passive safety features: much more than airbags
When many consumers think about vehicle safety, their first thought is airbags. As critical as these safety features are, there are far more considerations involved in occupant safety. As the latest BMW SAV®, the new X5 sets a new standard for the class in this regard, just as it does in active safety.

In developing the all-new X5 structure, BMW set out to exceed the demands of the world's most stringent governmental safety regulations, by minimizing impact loads on the occupants and by keeping the passenger space as intact as possible in many severe crash scenarios. Among the specific goals were –
• Achieving excellent results in the Euro-NCAP (New Car Assessment Program) offset frontal crash test, in which 40% of the vehicle's width impacts a fixed barrier at 40 mph.
• Meeting the recently introduced Ú.S. FMVSS (Federal Motor Vehicle Safety Standard) 301, which specifies a brutal 50-mph rear-end offset crash. This impact is taken by 70% of the test vehicle's width; not only must stringent injury criteria be met, but the fuel system must remain free of leaks. With or without the available 3rd-row seating, the new X5 Series meets this extremely demanding safety standard.
• Meeting the also relatively new IIHS 'SÚV side-impact' test, in which an impact from a tall vehicle at 50 km/h (31.1 mph) is simulated.
• Withstanding the Euro-NCAP side-impact test, in which a vertical pole is pushed into the vehicle side at 29 km/h (about 18 mph); this test simulates a vehicle sliding sideways into a tree or telephone pole.

Reaching those goals required diligent efforts in designing the new X5 body structure, wîth particular emphasis on overall structural rigidity of the passenger compartment; selection of materials such as aluminum or high-strength steel; energy absorption and deformation paths; and component placement—including engine and transmission. (posted on conceptcarz.com) Even such elements as wheels and tires were considered for their energy absorption capability. In addition, specific considerations and testing included both 5- and 7-passenger configurations of the X5. The results affected everything from the overall body structure to the design of an all-new §teering column.

Rollover Sensor
The system featured on the X5 is an outgrowth of BMW's work in designing roll-over protection systems for its convertibles. In the X5, the Rollover Sensor is networked wîth the vehicle's Dynamic Stability Control, which delivers data on lateral acceleration ('cornering') and any possible skidding. The Rollover Sensor measures the body's angle along its longitudinal axis, and the rate at which that angle is changing. Additionally, acceleration data in two directions are measured to test the plausibility of a rollover. On the basis of these measurements, an algorithm determines if the vehicle is about to roll over. If this is the case, the front and rear Head Protection System is deployed on both sides, and all safety belts wîth tensioners are tensioned.

Safety belts & airbags
As wîth all BMWs, 3-point safety belts are supplied for all seating positions, including the optional 3rd row. Likewise, all positions include force limiters, as well as adjustable head restraints. Front seats also include belt tensioners, along wîth dual-stage front airbags and seat-mounted (instead of the previous door-mounted) side-impact airbags. BMW's curtain-type Head Protection System covers front and 2nd-row seats. Front airbags are newly configured to optimize their 2-stage, accident-severity-dependent deployment characteristics, inflated shape, and interaction wîth surrounding surfaces and components. The X5's new body structure makes the previously available rear side-impact airbags unnecessary.

A mid-size crossover SUV unveiled in 1999, the BMW X5 was BMW's first SUV also known as 'Four-by-Four' in the UK. All BMW X5's are manufactured in Spartanburg, South Carolina. The X5 comes with all-wheel drive and is available with either manual or automatic transmission along with a range of gasoline inline-6s, V8s and diesel engines are available. Rather than being a SUV, BMW describes the X5 as a Sport Activity Vehicle (SAV) to shift emphasis on its on-road capability despite its size. The BMW X5 brought about the shift from truck-based body-on-frame SUVs to sedan-based crossovers that would have occurred in the late 2000s. The X5 was powered by the V8 4.4i with a manually shiftable five-speed automatic transmission.

In the late 1990s, Chris Bangle came up with the first sketches at the BMW DesignworksUSA studio in California, and in many ways, the current X5 still closely resembles these initial sketches. Rover's takeover ended up being helpful for BMW in the area of development of the X5. The engineers at BMW were able to review and use Range Rover technology and parts in their design of the X5, including hill-descent control. The design of the X5 was heavily influenced by its British counterpart, included the two-piece tailgate taken directly from the Range Rover. Numerous parts and electronics were also taken directly from the E39 5 Series parts bit to save on costs.

The X5 was designed as a sporting road car, in contrast to the Range Rover models, unfortunately the X5's off-road capabilities were significantly less than those of Land Rover. BMW made it well known that the X5 was referred to as an SAV rather than a SUV. Though the X5 was an all-wheel drive vehicle, BMW chose from the start to route 62% of the engine's torque to the rear wheels, working hard to make it feel as similar as possible to the company's rear-wheel drive sedans.

BMW launched a smaller version, the X3 in 2003, which used the ‘X' prefix applied to the BMW SAVs which were derivatives of the BMW number-series models.

The first generation of the BMW X5 crossover vehicle was introduced in 1999 and was produced until 2003 and had a wheelbase of 110.0 inches, an overall length of 183.7 inches and a width of 73.7 inches. The X5 was produced until September of 2006 and was replaced by the BMW E70. At the time that the E53 was developed, BMW still owned Land Rover and because it this is shares many of the components and designs with both Land Rover and also the BMW E39 5-series.

For 2001 no changes were made on the BMW X5. For 2002 the high-performance 4.6is model was introduced with a 340-horsepower V8 engine. Against Mercedes-Benz ML 50/ML55 AMG, the X5 was quite a big contender. Along with this were aero body add-ons, and the new model received 20-inch wheels along with a special sportier interior. For this year option packages received some content revisions.

The Premium group now came with rain-sensing wipers, a sunroof for both the 3.0i and 4.4i and automatic climate control for the 3.0i. The 4.4i edition could also be equipped with a new Rear Climate package that included privacy glass and rear window shades. Optional were rear torso side-impact airbags.

For 2004 the X5 didn't change much and a revised model was debuted in 2004. The all new X5 was revamped completely, and a new 6-speed manual transmission option, and a 315 hp V8 compared to the previous year's 290 hp in 2004. The 04 X5 also received new headlights, a few new exterior colors, upgraded engines and a new four-wheel drive system. The grilles were enlarged along with their actually slats being modified in a ‘flame surfaced' style. The X5's headlights received ‘angel-eyes' which were rings or halos around all front headlamps.

The 2004 taillights also received a similar facelift to the BMW E39 and the exterior glass was transformed from a ‘dotted' pattern to a cleaner ‘line' pattern. Called xDrive, BMW invented a new four-wheel drive system that was shared both in the X5 and X3 in 2005. Rather than using the earlier X5 system which had consisted or power being split 62-38 (rear wheels – front wheels) and DSC to brake wheels losing traction, the xDrive could vary power to the front or rear axles in milliseconds which transferred up to 100% of engine power to either axle, therefore allowing the vehicles to regain traction quickly.

Additional extras were added to the 2004 X5 were soft-boot close feature which allowed the top part of the trunk to pull itself closed, Trailer Stability program which made it an ideal tow vehicles and adaptive headlights. At the end of 2003 it was originally announced along with the rest of the X5 facelift, the X5 4.8is first started shipping in April 2004. Replacing the 4.6 L engine was a new larger 4.8 L engine that was also later used in the 2005 750i/Li. It also included a slightly modified bodykit, 20' wheels and along with the 4.6is were the only X5's ever to feature large chrome-tipped exhaust which hid the quad pipes.

For the 2005 version a few optional versions became standard on BMW's American-built SUV. The 4.4i offered newly standard front and rear obstacle detection which was optional on 3.0i. Now steering linked were Xenon headlights which were standard on V8s and optional on the 3.0i. Along with the rest of the BMW lineup (apart from the E65 7 series) the 2005 X5 received Bluetooth kits straight from the factory if ordered with the Premium Package.

For the 2006 BMW X5 no significant changes were made. The X5 wasn't fitted with the new BMW R6 engine which upped power for both the 2.5i and 3.0i I6 versions of the 2006 X3 and Z4 significantly. Some rumors implied that BMW held back deploying the engine in the 2006 X5 so they didn't waste development costs in retooling the assembly line so they could make way for a more dramatic unveiling of the new 2007 BMW X5. This year was also the end of the E53 X5 as well.

The second generation of the BMW X5, the E70 was introduced in 2008 and had a wheelbase of 115.5 inches, a length of 191.3 inches, a wheelbase of 115.5 inches and a width of 76.1 inches. The E70 is the current X5 SAV which replaced the BMW E53 in November of 2006. The E70 platform replaced the BMW E53 as the X5's underpinnings. A ton of new technological advancements were introduced on the E70-based X5 SAV including BMW's iDrive system as standard equipment, and the first for a BMW, an optional third row seat.

This current generation incorporates safety innovations for the crossover segment like a unique rear framing section that protected 3rd row occupants from injury due to an impact. From late 2008 until the new BMW branding scheme, the X5 3.0sd is now called the X5 XDrive 35D and the 4.8 i is called the X5 XDrive 48I.

During the spring of 2000, a lower-priced six-cylinder 3.0i edition was introduced with a standard five-speed manual transmission and optional four-speed automatic. Both of these models were produced in South Carolina on an exclusive uni-bodied platform. BMW X5's came with a standard permanently engaged four-wheel drive, traction control, all-disc antilock braking, an antiskid system and a tailgate with separate lift glass.
Not intended for severe off road use the X5's four-wheel drive system lacked low-range gearing. Instead, the XM automatically brakes individual wheels to limit slippage in low-grip conditions. The speed was limited to 6 mph down steep slopes down a standard hill descent control.

The standard equipment included power tilt/telescopic steering wheels, 70/30 split folding rear seats and front side-impact airbags which were head-protecting tubular airbags that deployed from above front door windows in a side impact.

Optional on the X5 were rear lower-body side airbags. A load-leveling suspension was included on the 4.4i and optional for the 3.0i, along with 18 inch wheels and tires, wood interior trim and leather upholstery. A Sport Package was available and included black exterior trim, a sport suspension and the 4.4i received 19-inch tires. Available with either model was an optional navigation system with dashboard-mounted video screen. The biggest competitor for the X5 was the Lexus RX 300, the Mercedes-Benz M-Class and the Acura MDX.

BMW produced a one-off version of the X5 that was dubbed the X5 LM and equipped it with the M70 S70B56 V12 engine from the Le Mans winning BMW V12 LRM. In 2000 it was driven by Hans Joachim Stuck to receive a lap record at the Nürburgring.
