Although the X5 has all-wheel drive and is considered an SUV, it has no low-range for its four-wheel-drive system and it rides as close to the ground as other luxury SUVs which is around eight inches.

It favors sending most of the engine's torque to the rear wheels, great for handling, but it changes instantly when wheels at one end of the car start to slip. This is a good system for bad weather.
