An output power control apparatus for an internal combustion engine of a motor vehicle, which apparatus can enhance drivability of the motor vehicle regardless of shift operation of a transmission by suppressing positively abrupt start of the motor vehicle and shift shock due to increase of load applied to the transmission upon shift operation thereof from a neutral range to a drive range. The output power control apparatus includes an intake pipe (7) for supplying intake air to an internal combustion engine (6) mounted on a motor vehicle, a throttle valve (8) installed in the intake pipe (7) for regulating an amount of the intake air supplied to the engine (6), a throttle actuator (9) for adjusting an opening degree ( theta ) of the throttle valve (8), a transmission (13) for transmitting output power of the engine (6) to a wheel system of the motor vehicle, a shift information detecting means for detecting shift of the transmission (13) to thereby generate shift information (SR), an accelerator sensor (2) for detecting a accelerator pedal actuation quantity ( alpha ) which corresponds to a depression stroke of an accelerator pedal (1), and a throttle control means (15A, 15B, 15C) for setting a control quantity (C) for the throttle actuator (9) on the basis of at least the shift information (SR) and the accelerator pedal actuation quantity ( alpha ), wherein the throttle control means (15A, 15B, 15C) incorporates a control quantity suppressing means (16, 16B, 16C) for suppressing the control quantity (C) at least over a predetermined time period succeeding to shift operation of the transmission (13) when the shift information (SR) indicates the shift operation of the transmission (13) from the neutral range (N range) to the drive range (D range).
