A supercharged internal combustion engine has an exhaust gas turbocharger which includes an exhaust gas turbine and a compressor. The exhaust gas turbine and the compressor are connected to a turbocharger shaft and an appliance for the transmission of power for the purpose of a mechanical step-up drive capability for the exhaust gas turbocharger arranged between the turbocharger shaft and the crankshaft of the internal combustion engine. The appliance includes at least one step-up gear and a controllable hydrodynamic coupling for torque transmission arranged between the crankshaft and the turbocharger shaft. In order to configure the internal combustion engine in a simple and compact constructional manner in such a way that a better increase in torque of the internal combustion engine can be achieved in the lower rotational speed range by the mechanical step-up drive of the exhaust gas turbocharger and to achieve substantially shorter response times during transient operation of the internal combustion engine, the hydrodynamic coupling can be locked up by a mechanical or electro-mechanical clutch and is arranged between the step-up gear and the crankshaft of the internal combustion engine.
