Testing On A One-Axle Roller Test Stand For AWD Vehicles

During this test, the wheels of one axle are driven in opposite directions, to prevent delivering power to the other axle.
The test speed must not exceed 6 km/h (4 mph), otherwise the brakes may lock up due to the roller start-up delay (EDL regulation).
Test stands approved by Audi meet these requirements.
