Bmw X5 #9

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 U.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 “SUV 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, with 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. 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 steering 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 with 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 with tensioners are tensioned.

Safety belts & airbags
As with 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 with 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 with surrounding surfaces and components. The X5’s new body structure makes the previously available rear side-impact airbags unnecessary.

Packages & options: new content and packages complement familiar features

Panoramic moonroof: Dual-pane roof includes 1-touch operation and interior sunshade.

Rear manual side window sunshades: Available as a stand-alone option (SOP tba).

Multi-contour Front Seats: Available as a stand-alone option or as part of the Active Ventilated Seats Package, these seats offer 20-way adjustability.

Heated front seats: Available as a stand-alone option or as part of the Cold Weather Package, these front seats offer 4 heating zones, rapid heating and 3-stage heating.

Rear-seat heating: Provides 3-stage heating for the 2nd-row seats. Requires Cold Weather Package or heated front seats.

3rd-row seating: Adds 3rd seating row to accommodate two additional passengers.
The 3rd-row seats fold flush into floor, and the option includes adjustable 2nd-row seating with flush-fold function and easy-entry to 3rd row. Both rows fold to provide a completely flat cargo floor. On 3.0si, the option also includes the self-leveling rear suspension, which is standard on the 4.8i.
Audi humbles Porsche. A new dawn starts today.

Being nice since 2007.
