Abstract: A vehicle includes an internal combustion engine, a catalyst provided in an exhaust passage of the internal combustion engine, and an electronic control unit. The electronic control unit is configured to control an engine torque such that a first torque change amount of the engine torque when the temperature of the catalyst belongs to a predetermined low temperature region to be lower than a second torque change amount of the engine torque when the temperature of the catalyst belongs to a high temperature region. The high temperature region is a region having a temperature higher than the low temperature region.
