BMW xDrive is the marketing name for the all-wheel drive system found on various BMW models since 2003. The system uses an electronically-actuated clutch-pack differential to vary the torque between the front and rear axles. Models with the DPC torque vectoring system also have a planetary gearset to overdrive an axle or rear wheel as required.

Early rotary kiln systems, on the other hand, had feed residence times of 3-6 hours, while the fuel/air mix passed through the system in about ten seconds. In addition, conditions within the system were visible and, in principle, measureable, so control became a continuous process of reaction to observed changes within the system.
