An engine torque control device is configured to reduce shift shock during a downshift with an automatic transmission. During a downshift with an automatic transmission having a stepped shift mechanism, when the engine output (torque) is increased so as to bring it closer to being synchronized to the post-downshift engine speed, and then the torque is reduced sharply enough to maintain the synchronizing speed, and when synchronizing control is concluded so that the torque is sharply reduced to the driver's required torque in a state in which the accelerator is released, the throttle opening is reduced while any extra torque resulting from a reduction lag in the intake air quantity is cancelled out by retarding the ignition timing, thereby sufficiently lessening shift shock.
