When the BMW X5 first appeared in 2000, it redefined the premium sport-utility vehicle §egmènt and sent many competitors back to their drawing boards. This was BMW's first light-duty truck that not only brought the newest in manufacturing and technology advances to consumers worldwide, it also introduced the 'Sports Activity Vehicle®' concept that would later grow to include the 2004 X3 and the second-generation X5 that was introduced for 2007. The BMW SAV concept continues today and expands wîth the introduction of the X5 xDrive35d, a diesel vehicle utilizing BMW Advanced Diesel wîth BluePerformance Technology, linking handling, performance and efficiency to the conventional attributes of practicality, versatility and off-road capability.
For 2009, the second-generation X5—which launched in 2007—returns wîth revised features to keep it abreast of the competition and builds upon its recently-launched technology and performance: the Automatic Tailgate has been added to the Premium Package; Heated Rear Seats have been added to the Cold Weather Package; Optional Nappa Leather now includes a Leather Wrapped dashboard; the iPod/ÚSB Adapter has been added to the X5 xDrive48i's Premium Sound Package and is no longer available as a stand alone option; the Rear Self Leveling Suspension on the 48i has been deleted from the standard equipment profile and is included on 3rd Row Seat optioned vehicles; and the Space Saver spare is now a stand alone option.
In addition to the new diesel model, the 2009 X5 still offers a choice of 6-cylinder
(X5 xDrive30i) or V-8 (X5 xDrive 48i) engines: both providing performance and excellent efficiency. The flagship 48i boasts BMW's all-aluminum Valvetronic V-8, wîth 350 horsepower. The 30i features BMW's aluminum/magnesium inline-6 rated at 260-horsepower. Standard equipment on both models is a 6-speed STEPTRONIC automatic. 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.
The 2009 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.
The X5's front suspension represents a break from 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.

power, torque and remarkable fuel efficiency. All wîth refinement and sound worthy of a BMW.
In Europe, where fuel prices have historically been – and remain – much higher than in the Ú.S., vehicle manufacturers have achieved dramatic gains in the performance, smoothness, quietness and emission control of diesel engines…while maintaining the diesel's historic superiority in fuel efficiency. Now, wîth the new X5 xDrive35d, BMW brings this progress to the Ú.S., wîth brand-new technology that meets the Ú.S.' strictest emission standards. ( posted on conceptcarz.com)
Like all '09 BMW gasoline engines, the X5's new diesel is constructed wîth a weight-saving aluminum cylinder block – something that's not taken for granted given the diesel's much higher compression pressures. (All BMW engines have aluminum cylinder heads.) It is an inline 6-cylinder engine maintaining a defining BMW tradition that means exceptional smoothness and unique sound.
In addition, several diesel-specific technologies of this new engine contribute to its achievement of true high performance, diesel fuel economy and clean exhaust:Common-rail direct fuel injection
. One of the most important innovations of recent diesel development, this has replaced the individual-cylinder or distributor-type injection systems of earlier diesel engines.
Common Rail (CR) means that a single, very high-pressure fuel-delivery pump supplies all cylinders, the fuel traveling along a common 'rail' or distributor line. From there, fuel is injected at extremely high pressure (1800 bar/26,000 psi) directly into the cylinder.
The basic novelty of common-rail injection was to divorce the production of fuel pressure from the actual injection process; this was necessary to give the diesel engine what gasoline engines have long had, namely completely electronically controlled fuel injection. CR also facilitates multiple injections per combustion cycle. In all, this was a breakthrough that made possible dramatic strides in diesel power, efficiency and emission control.Piezo injectors.
A further breakthrough, already applied by BMW in other models' twin-turbo gasoline engines. With direct injection, the injectors – that critical component injecting fuel into each cylinder's combustion chamber – are subject to especially high temperatures and pressures. Instead of most injectors' conventional electrical valves, a 'stack' of piezo crystals reacts lighting-fast to impulses from the engine electronics governing the injector needle's opening stroke and duration for ultra-precise control. This, too, facilitates major advances in fuel economy and emission control, in gasoline, as well as diesel engines.Sequential Twin Turbo technology.
In contrast to the two small, equal-size turbochargers of BMW's twin-turbo 6-cylinder and V-8 engines, the diesel employs two turbos of different sizes.
At low engine speeds, intake air does pass through the large turbo, but it's the smaller, lower-inertia one that does the air compressing (turbocharging). Thanks to its optimum efficiency within this rpm range, it provides effective boost for driving from a standstill up to modest acceleration rates and driving speeds. So it is that this engine develops a good 390 lb-ft. of torque at as low as 1500 rpm – a remarkable achievement that will amaze first-time X5 xDrive35d drivers and continue to thrill those who drive this BMW regularly.
With increasing engine speed, the larger turbocharger begins to take over: first as a pre-compressor for the smaller one, then progressively until it becomes the primary turbo. The engine reaches its maximum of 425 lb-ft. by 1750 rpm, then maintains this immense torque level until 2250 rpm going on to reach its peak power of 265 hp at 4200 rpm.
Diesel combustion, power and torque characteristics. In its most basic distinction from gasoline engines, a diesel engine achieves its combustion not wîth a sparkplug, but by much 'harder' compression of the fuel-air mixture; the X5 xDrive35d engine, for example, has a compression ratio of 16.5:1, vs. 10.7:1 and 10.5:1 in the gasoline engines of the X5 xDrive30i and 48i, respectively.
The diesel combustion process also produces very different torque and power characteristics. For example, the 48i's V-8 engine reaches a maximum torque of 350 lb-ft. @ 3400 rpm and a maximum power of 350 hp @ 6300 rpm, while the six cylinder engine of the 35d attains its maximum torque of 425 lb-ft. @ 1750-2250 rpm and its maximum power of 265 hp @ just 4200 rpm. In general, diesels have this low-speed-torque, lower-rpm character and in their vehicular application, they are geared differently. As such, an automatic is the ideal partner for a diesel engine.
Diesel engines also employ a different fuel, the product of a different refining process from that of gasoline. The two fuels are not interchangeable; gasoline cannot be used in a diesel engine and vice versa. Their prices typically diverge; at any time or in any location, demand may be different for the two, and government taxation policies for gasoline and diesel fuel also diverge.Stellar pulling moxie, full-bore acceleration – and fuel efficiency
. The huge torque output of 425 lb-ft. at relatively low engine speeds speaks for itself; X5 xDrive35d drivers will marvel at this engine's robust response at low to medium speeds. The peak power output of 265 hp also speaks for itself, as does the resulting 0-62-mph time of 7.2 sec. Fuel efficiency is truly impressive at 18 mpg city and 26 highway, good enough for a $1,550 tax credit or those who purchase the X5 xDrive35d.Most advanced exhaust gas management: SCR catalyst wîth AdBlue injection.
BMW Advanced Diesel wîth BluePerformance optimizes emission management by incorporating an oxidation catalyst placed close to the engine, a diesel particulate filter housed in the same unit, and an SCR catalyst wîth urea injection. Apart from filtering out even the smallest particles from the flow of exhaust gases, this combination ensures effective reduction of nitric oxides (NOX) by way of a chemical reaction within the exhaust system initiated by the injection of a small dose of urea referred to as AdBlue. The ammonia (NH3) generated in this process within the SCR catalyst subsequently converts the nitric oxides (NO and, respectively, NO2) in the exhaust gas into environmentally compatible nitrogen (N2) and vapor (H2O).
BMW has developed a two-tank system for AdBlue ensuring convenient use of this new technology wîth all the benefits and ease required by the customer: The amount of AdBlue required in each case is drawn from the active tank comprising approximately 1.6 gallons by means of a dosage pump. And since the urea solution would freeze at a temperature of -11 -degrees C, this active tank, as well as the dosage pipes are heated.AdBlue technology by BMW: reduced emissions without additional service appointments.
The active tank is connected to a second reservoir, the so-called passive tank. With its additional capacity of approximately 4.5 gallons, this passive tank offers a plentiful supply of the urea solution required within the SAV. The average range provided on this supply capacity is indeed sufficient to have the tank system replenished as part of normal scheduled maintenance.
From the active tank AdBlue is delivered to the dosing valve and atomized into the exhaust emissions. Consistent distribution of AdBlue within the flow of exhaust emissions is ensured by the SCR mixer. The ammonia generated in this way in the hot emission gas subsequently acts in the SCR catalyst as a reduction agent and converts environmentally harmful nitric oxides into nitrogen and water vapor in a process referred to as Selective Catalytic Reduction.
This process gives the special SCR catalyst its name wîth the SCR system as such being masterminded by highly efficient engine management. A nitric oxide sensor, finally, provides information on the concentration of NOX in the exhaust emissions.
The large amount of AdBlue provided in the reservoir enables the customer to go on driving as before without having to change service intervals or observe any particular requirements, thus benefiting from the advantages of this environmentally friendly emission technology throughout the entire running life of the car without any additional service or visits to the workshop. During the first four years or 50,000 miles, the replenishment of AdBlue will be covered as part of the BMW Scheduled Maintenance program: not only will there be no additional inconvenience, but no addition cost during that period.X5 xDrive30i: The most recent edition of BMW's trademark inline-6
BMW's most recent 6-cylinder engine powers the X5 xDrive30i. 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.Key attributes of this engine include:
• Great power, 260 hp– a very impressive 86.8 hp/liter.
• Great torque, 225 lb-ft., strong 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. 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 15 mpg city / 21 mpg hwy wîth the new rating system
The benefits are all part of a concerted effort to make across-the-board improvements in engine performance. It is a fundamental part to BMW's EfficientDynamics program where you put less in and get more out.
Much of the weight savings in the engine, for instance, is the result of the 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 xDrive48i'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.
Obviously, the adoption of the Valvetronic system also plays an important part in improving performance and efficiency. 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. All together, the new engine delivers tangible performance that can be witnessed as such: 0-60 mph in 7.8 sec.
X5 xDrive48i: The original Valvetronic V-8 delivers more power and torque wîth the same refinement
Únder the X5 xDrive48i's 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.
At 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 high torque peak of 350 lb-ft. occurs over a range from 3400 to 3800 rpm. Horsepower is also 350 and EPA rates the X5 xDrive48i at 14 mpg city / 19 mpg hwy.Standard on all models: an evolved 6-speed STEPTRONIC
This incredible automatic transmission also benefits from a number of refinements in the X5, designed to improve both performance and fuel efficiency—particularly in the case where finding the perfect gear for any given road condition is of paramount concern in the sporting X5.
The transmission also features an 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 and 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 is 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, features three stages instead of two. This provides finer adaptation to driving style and conditions.
An additional advantage of the 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
As wîth last year's model, the 2009 X5 also utilizes a number of technologies designed to reduce fuel consumption, which in turn lowers CO2 emissions, as part of BMW's Efficient Dynamics. 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 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 body structure heightens the X5's 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 over the previous generation X5.
This 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 tradition.
The current generation's 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 front suspension is a 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's multi-link 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 2009 X5 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 wide front and rear track on the X5 improves agility, while a longer wheelbase improves ride and increases interior space. Únique in the §egmènt: Active Steering and AdaptiveDrive.
The 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 assist for optimal power §teering boost at all speeds. Active Steering can also help to stabilize the X5 should the driver experience the onset of oversteer or understeer 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 and straight line.
Carefully coordinated interaction of the anti-roll bars and shock absorbers by way of AdaptiveDrive, part of the optional Sport Package, is equally unique in the X5'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. By simply 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 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 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, so all three received significant attention.
The brakes themselves are evolutionary, wîth ventilated cast-iron rotors all around on both models. Braking power has been enhanced by large diameter brake rotors:X5 xDrive30i:
Front: 332mm/13.1in., rear: 320mm/12.6in.X5 xDrive48i:
Front: 348mm/13.7in.; rear: 345mm/13.6in.X5 xDrive35d:
Front: 348mm/13.7in.; rear: 320mm/12.6in.
Like the rest of BMW's 2009 lineup, the X5's Dynamic Stability Control 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 come standard wîth 18-in. wheels and tires. Sport Packages for both models include 19-in. wheels wîth all-season tires. In addition, the X5 xDrive48i offers 20-in. equipment as an option in combination wîth its Sport Package.
Every '09 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 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 X5 marks a significant evolution in xDrive capabilities, which has always depended upon a networking of Dynamic Stability Control and the xDrive system. With the overall Integrated Chassis Management system, 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 current X5 looks – and is – even more dynamic, more muscular, and more elegant. The 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 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. The interior and long wheelbase 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 self-leveling Xenon Adaptive units. 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 BMW has achieved this goal, wîth aerodynamic drag coefficients of 0.34 for the 30i, 0.35 for the 48i.
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
The 2009 X5 provides the ideal setting for expanding interior and cargo volume, wîth an array of new amenities and upgrading the general level of technology enjoyed by the driver and passengers.
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 electric transmission selector. At the same level is the iDrive monitor. 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.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 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
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
Standard power seats include power head-restraint adjustment, making them 10-way adjustable. 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 Comfort Seats are also available either as a stand-alone option or as part of the optional Active Ventilated Seats Package.Storage and control
The center 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 electro-hydraulic parking brake.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 wîth new colors, typography, legibility and contrast under all conceivable light conditions.
Six frequently used functions can be stored on the 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 has separate left/right rotary controls for temperature settings, and 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 system. Temperature and volume controlled air vents are standard. In addition, temperature and air distribution settings are included in Vehicle & Key Memory on both the 30i and 48i.
For 2009, Heated Rear seats have been added to the Cold Weather Package. 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 2009 X5 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 30i model, and is once again available in Sand Beige or Black. The Nevada leather upholstery, standard in the 48i and optional in the 30i (as part of the Premium Package or a stand-alone option), is available in Sand Beige, Black, Gray or the new Tobacco. For 2009, optional Nappa Leather now includes a Leather Wrapped Dashboard. 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 X5's interior also includes premium materials on the door panels, dashboard and controls. In addition, a variety of trim materials are available on both the 30i and 48i, including Dark Burl Walnut Wood (standard), 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 X5's large in storage capacity has been achieved partly by the 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.
For 2009, an 18-in. space-saver spare wheel and tire is available only as a stand alone option. 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. The 2009 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 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. 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 2009 X5 sets a new standard for the class in this regard, just as it does in active safety.
In developing the 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 the engine and transmission 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 rollover 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.Packages & options:
