A hybrid electric vehicle (HEV) includes an internal combustion engine, an electric traction motor, a motor/generator configured to start the internal combustion engine, a transmission, and a powertrain control system including a controller having one or more processors. The controller is programmed to monitor the transmission for a gear shift while the HEV operates in an EV mode where the electric traction motor provides propulsion for the HEV, detect a driver torque request during the gear shift, and turn the internal combustion engine on to provide torque to the HEV during the gear shift.
