| Test on a single-axle brake dynamometer for four-wheel drive vehicles |
| The rollers drive the wheels of one axle in opposite directions to avoid transmitting torque to the other axle. |
| Test speed must not exceed 6 km/h. Otherwise the EDL control can activate the brakes if the rollers start at different points in time. |
WARNING | The Torsen differential will be seriously damaged if test speed exceeds 6 km/h. |
