The influence of non-uniformity of the torque of internal combustion engines on the car's pulling power. It is found that this irregularity leads to unproductive vehicle additional energy costs. The estimation of reducing unnecessary loss of engine power to move the car using a hybrid electromechanical actuator drive wheels. A method for estimating the overhead power car traffic and the criterion for their assessment, which is an additional energy consumption related to the work of the external resistance movement forces the car. An analytical expression for the ratio of unproductive energy losses car with a hybrid electromechanical drive the drive wheels.
