A hybrid vehicle having an engine, an electric machine, and a step-ratio transmission includes a controller programmed to, in response to an accelerator lift-pedal event when operating in a towing mode, learn a vehicle speed, and apply a lift-pedal torque when vehicle speed exceeds the learned vehicle speed, and apply an adjusted lift-pedal torque based on a gear ratio after downshifting the transmission to maintain a constant output shaft torque otherwise.
