All-wheel drive vehicles
Test on a 1-axle test stand for AWD vehicles

During the test the two wheels on an axle are driven in opposite directions so that no drive is transferred to the other axle.

The test speed must not exceed 6 km/h, otherwise the time delay in setting the rollers in motion could cause the brake control systems to intervene (EDL control).


CAUTION: The Torsen differential will be destroyed if test speed exceeds 6 km/h.

The Audi-approved test stands meet these criteria.
