28.5 percent of the Australian buyers opted for BMW's xDrive system. BMW Australia currently offers 11 models equipped with such a technology, including X6 (three versions), X5 (four versions) and X3 (four versions). Moreover, the company plans to introduce xDrive on new models, such as the whole X1 range.
The xDrive system was first unveiled at the 2003 Frankfurt Motor Show when BMW installed the technology on X3 and X5. However, all-wheel drive systems have been used by the German manufacturer since the '80s, while the 1999 X5 brought several innovations when it comes to such technologies.
“The "heart" of this new system is the electronically controlled multiple-plate clutch enabling xDrive to spread out drive forces infinitely and fully variably between the front and rear axle. The system immediately recognizes the need for a change in power distribution and responds extremely quickly, on the road usually before the wheel involved has even lost its grip. As a result, both the X3 and the X5 run like on rails even under adverse conditions, DSC stability control not being required to cut in until a far later point in time than with other drive concepts,” BMW praised the features of its all-wheel drive system in 2003.
