BMW's new DSC system further enhances safety through various additional functions. First, Brake Fade Compensation works to counteract any decrease in brake power at extremely high temperatures by increasing brake forces accordingly (anti-fading support). Brake Standby provides a moderate build-up of brake forces in emergency situations which may require sudden deceleration. Brake Drying, as yet another example, optimizes the performance of the brakes in the wet, while the start-off assistant makes it easier to start off on an uphill grade. The parking brake of the new X5 uses both an electro-mechanical and hydraulic function activated or released at the touch of a button.



Dynamic Traction Control for greater spin and more dynamic performance

Reflecting its high standard of driving dynamics, the new BMW X5 also comes with Dynamic Traction Control. All the driver has to do to activate the DTC mode is press a button on the center console. This raises the threshold for intervention of the engine and brakes by DSC, allowing the BMW X5 to set off smoothly on loose snow or sand with the drive wheels intentionally spinning slightly. Last but certainly not least, DTC promotes an even more sporting and active style of driving by allowing more wheel-spin before intervening.

The high-performance brake system in 2007 BMW X5, supported by the wide range of new DSC functions, ensures excellent stopping power in every situation. Vented discs on all four wheels ensure maximum braking efficiency.

Brake disc diameters on the BMW X5 3.0si are 13.1 inches in front and 12.6 in the rear. On the X5 4.8i, in turn, the corresponding measurements are 13.7 and 13.6 inches respectively.



First SAV featuring runflat tires standard

The new BMW X5 is the first vehicle in its class with runflat tires standard. These tires, which are mounted on extended hump rims, are the fourth generation of runflat tires. Runflat tires allow the driver to go on driving even after a complete loss of tire pressure. The driver can continue up to 90 miles at a speed up to 50 mph even with the vehicle fully loaded.

Both models of the new BMW X5 come standard with 18-inch light-alloy wheels with 255/55 all-season tires. Larger 19-inch light-alloy wheels with all-season tires are included with the optional sports package. On the X5 4.8i with Sport Package, 20 inch wheels with 275/40 front and 315/35 rear performance tires may be ordered. Here again, the tires are runflats.

The standard Tire Pressure Monitor warns the driver of a gradual loss of air pressure. Consistently monitoring actual tire pressure, this system registers any deviation from normal pressure. A graphic symbol in the instrument cluster display informs the driver whenever the system detects a loss of pressure.



Dynamic and efficient V8 performance

It goes without saying that a premium segment SAV requires and deserves a choice of powerplants which provide impressive torque and power combined with outstanding running refinement. For the U.S. there will be two models, one six cylinder and one V8.

The V8 in the BMW X5 4.8i offers a high level of performance at all times. Upgraded and renewed in virtually every respect, this top-of-the-line engine develops a maximum output of 350 hp from an engine capacity of 4,799 cubic centimeters. In addition to double-VANOS variable camshaft adjustment and VALVETRONIC fully variable valve drive, the V8 now comes with even more sophisticated and efficient engine management.

The V8 in the new BMW X5 4.8i develops maximum torque of 350 lb-ft from 3,400 to 3,800 rpm, offering efficient dynamics of the highest standard. Accelerating from a standstill to 60 mph in 6.4 seconds, this top-end model will not disappoint the true driving enthusiast.
