Abstract: ABSTRACT            The invention is directed to a method of and an apparatus for determining the engine power of an automotive vehicle on a roller dynamometer the rollers of which can be braked with a constant brake power. In accordance with the invention, in a first measuring operation the net power of the engine acting on the vehicle wheels is determined by sensing the braking power acting on the dynamometer rollers. In a second measuring operation, the slowing-down time (t1) is measured within which the speed has decreased from a predetermined value (v1) to a second preselected value (v2) with unbraked dynamometer rollers. In a third measuring operation the dynamometer rollers are braked with a constant brake power and the slowing-down time (t2) is measured within which the speed has decreased from the initial value (v1) to the preset final value (v2), There-after, the internal power loss (Px) of the automotive vehicle is calculated in accordance with the following equation:              Px =         The gross power of the vehicle engine may be determined by adding the calculated power loss to the previously measured net power.
