BMW has been careful not to tamper too greatly with the exterior shape, which has won over the hearts of buyers despite initial controversy. For the second generation car subtle enhancements have been made, including a small increase in overall length. The design is a subtle evolution of the old car, increasing aerodynamic efficiency to aid economy whilst retaining the key design features of all BMWs. Mechanically there are some significant changes too, designed to improve the X5's ability both on and off-road. Most significant is the use of double-wishbone front suspension, the first such application on production BMW and an arrangement ideal for producing high standards of ride and handling. It also comes with X-Drive, a four-wheel drive system which distributes the power between individual axles to make the most of the available grip. For the first time the X5 is available with features seen elsewhere on BMW cars, such as Active Steering and Adaptive Drive.
The Active Steering system changes the ratio of the steering, giving very quick and light steering at low speeds for easy parking, then at higher speeds increasing the ratio and reducing the power assistance for improved feel. Adaptive Drive uses electronically controlled anti-roll bars to simultaneously give a smoother ride yet minimal body roll. A further key difference between the second generation X5 and its predecessor is the availability of seven seats. This has been made possible by an increase in the vehicle's dimensions, as well as a rearrangement of the load area. The rear pair of seats are designed for child use only, and can be folded flat into the boot floor to give a large load space. The second generation X5 could not be as great a leap forward as the original car was, but its overall competence is truly excellent. The looks are subtly improved, the cabin is smarter and more spacious and the driving experience is better than ever, with more powerful and fuel efficient engines and better ride and handling.
Running costs will be relatively high given the performance and size of the X5, although the difference between the diesel model and the V8 petrol will be quite considerable. The bigger exterior dimensions has resulted in greater interior space, and even with five adults aboard the X5 is a spacious car. Head, leg and elbowroom are all in plentiful supply, while the boot is also large. Storage space within the cabin is less plentiful, as there are numerous cubbies but many of them are relatively small. As with most BMWs, the cabin layout in the X5 is excellent. All the controls and displays are clearly labelled and sensibly laid out, with the large number of minor functions taken care of with the I-Drive controller. A new addition for the second generation X5 is a joystick-style gearlever, which requires much less effort to use and takes up less space. Another strong point of the X5, comfort is impressive throughout. The front seats are particularly good, with a wide range of adjustment.
The second row are also good, although the third row where fitted is suitable for children only. Road and wind noise are very well suppressed, while the engines only make their presence felt when revved, making for a very comfortable cabin. All X5 models are fitted with a Category 1 approved alarm and immobiliser, as well as anti-theft bolts on the alloy wheels and remote central locking. The X5 is packed with standard safety equipment, including a full complement of airbags, ABS and stability systems as well as useful extra features such as hill descent control. Added to this is the extra security and stability of the standard four-wheel drive system for extra reassurance. They key to the appeal of the X5 its all round driving ability. In normal use it is a comfortable car, easy to drive and undemanding. All the engines are capable of relaxed cruising and have sufficient torque for easy progress.
