Disclosed are a hybrid electric vehicle and an engine control method therefor that are capable of reducing entry of an engine into a full-load drive mode. The method includes determining whether the extent of depression of an accelerator pedal (APS) may be equal to or greater than a reference value set as a condition for entry of an engine into a full-load drive mode, determining a part-load torque corresponding to the maximum torque in a part-load drive mode of the engine and a motor torque corresponding to the maximum torque of a motor when the extent of depression of the accelerator pedal may be equal to or greater than the reference value, comparing the sum of the part-load torque and the motor torque with a driver demand torque, and controlling the engine in the full-load drive mode or the part-load drive mode depending on a result of the comparing.
