A vehicle, comprising: an engine for generating a driving force by burning a fuel containing gasoline and alcohol; and a control device for controlling the engine, comprising: a content identifying unit configured to detect or estimate an alcohol content of the fuel; a determining unit configured to determine whether or not the vehicle is in a runnable state after the engine has started, wherein the runnable state refers to a state in which the vehicle is capable of starting to move mechanically; and a restricting unit configured to keep the output power of the engine lower than normal so that the starting of the vehicle is restricted or to cancel the restriction based at least on the identified alcohol content of the fuel and the determination whether or not the vehicle is in the runnable state, characterized in that the control device is further comprising an engine revolution speed detecting unit configured to detect a state of the engine based on a comparison of a detected cumulative number of revolutions of the engine after engine starting with a predetermined cumulative number of engine revolutions, wherein the restricting unit is configured to keep the output power of the engine lower than normal so that the starting of the vehicle is restricted or to cancel the restriction based on the identified alcohol content of the fuel, the determination whether or not the vehicle is in the runnable state, the detected state of the engine, and optionally an engine temperature detected by an engine temperature detecting unit. an engine for generating a driving force by burning a fuel containing gasoline and alcohol; and a control device for controlling the engine, comprising: a content identifying unit configured to detect or estimate an alcohol content of the fuel; a determining unit configured to determine whether or not the vehicle is in a runnable state after the engine has started, wherein the runnable state refers to a state in which the vehicle is capable of starting to move mechanically; and a restricting unit configured to keep the output power of the engine lower than normal so that the starting of the vehicle is restricted or to cancel the restriction based at least on the identified alcohol content of the fuel and the determination whether or not the vehicle is in the runnable state, a content identifying unit configured to detect or estimate an alcohol content of the fuel; a determining unit configured to determine whether or not the vehicle is in a runnable state after the engine has started, wherein the runnable state refers to a state in which the vehicle is capable of starting to move mechanically; and a restricting unit configured to keep the output power of the engine lower than normal so that the starting of the vehicle is restricted or to cancel the restriction based at least on the identified alcohol content of the fuel and the determination whether or not the vehicle is in the runnable state, characterized in that the control device is further comprising an engine revolution speed detecting unit configured to detect a state of the engine based on a comparison of a detected cumulative number of revolutions of the engine after engine starting with a predetermined cumulative number of engine revolutions, wherein the restricting unit is configured to keep the output power of the engine lower than normal so that the starting of the vehicle is restricted or to cancel the restriction based on the identified alcohol content of the fuel, the determination whether or not the vehicle is in the runnable state, the detected state of the engine, and optionally an engine temperature detected by an engine temperature detecting unit. an engine revolution speed detecting unit configured to detect a state of the engine based on a comparison of a detected cumulative number of revolutions of the engine after engine starting with a predetermined cumulative number of engine revolutions, wherein the restricting unit is configured to keep the output power of the engine lower than normal so that the starting of the vehicle is restricted or to cancel the restriction based on the identified alcohol content of the fuel, the determination whether or not the vehicle is in the runnable state, the detected state of the engine, and optionally an engine temperature detected by an engine temperature detecting unit.
