A vehicle includes an engine, an electric machine, an engine disconnect clutch, and a transmission input configured to transmit power from the engine and electric machine to a transmission. The vehicle also includes a controller program to close the disconnect clutch and start the engine before downshifting in response to an anticipated transmission downshift in which a predicted speed of the transmission input after the downshift will be outside a predetermined speed range or a torque capacity of the electric machine will be less than a predicted required torque after the downshift.
