An engine system includes an internal combustion engine, an electrical power system configured to provide electrical power in the engine system, and an electrified air system powered by the electrical power system to selectively increase a flow of intake air and exhaust gas to the engine. The electrified air system further includes an EGR pump operable to recirculate a portion of exhaust gas output from the engine and an electric turbocharger including a turbine, a compressor driven by the turbine via a shaft coupled therebetween, and an electrical machine coupled to the shaft. The electrical machine is configured to operate in a motoring mode to drive the shaft and cause the compressor to output boosted intake air to the engine and operate in a generating mode to transform rotational power from the shaft into electrical power that is provided back into the electrical power system.
