The purpose is to determine the power-off effect on course holding and directional behaviour of a vehicle, whose steady-state circular motion is disturbed by power-off only. The sudden release of the accelerator pedal causes this effect. It is not possible at present to use this procedure and test results for regulation purposes.</p>"
