If the system justifies it, Quattro Ultra will send 100 percent of available power to the front wheels by disengaging the front clutch, located at the transmission, and a second one fitted inside the rear differential. When additional traction is needed — say, when driving on sand or loose gravel, or accelerating hard through a corner — both clutches are engaged, pushing a portion of that power rearwards.
