A control system for a vehicle performs torque down control to reduce torque of an engine by cutting off supply of fuel to at least one of the cylinders of the engine during an inertia phase of a power-on upshift. During the torque down control, the throttle opening is reduced to smaller than a throttle opening including an amount by which the throttle opening is increased so as to compensate for a part of the amount of torque reduction, by means of one or more cylinders to which the fuel continues to be supplied.
