Abstract: The technical design relates to a roller testing station (1) for a motor vehicle (2) comprising at least one fixed roller (3) for rolling at least one driven wheel (4) of the motor vehicle (2) driven by a motor (5). A roller testing station (1) further comprising at least one braking means, at least one cooling means for cooling the parts of the motor vehicle (2) during the test, and at least one sensing means (6) for monitoring and recording parameters and test results. In the new technical design the braking means comprises at least one fan (7) interconnected with the fixed roller (3) by at least one of gear for transferring the rotational motion of the fixed roller (3) to the fan (7).
