An engine control method for a vehicle may include a temperature securing determination step of determining, by a controller, whether an exhaust gas temperature before a turbine of a turbocharger is normally secured; a basic determination step of, when the exhaust gas temperature before the turbine is normally secured, obtaining, by the controller, a first compensation torque according to a current state of the vehicle from a first compensation torque map according to the exhaust gas temperature before the turbine, an engine operation mode, engine speed, and atmospheric pressure; and an engine control step of, when the exhaust gas temperature before the turbine is normally secured, determining, by the controller, a final compensation torque on the basis of the first compensation torque and controlling engine torque at a value which is obtained by subtracting the final compensation torque from engine full-load torque.
