Methods and systems are proposed for controlling a temperature of exhaust gases generated by the engine by operating an E-Turbo of the vehicle. In one embodiment, a method is provided, comprising increasing a power generated by an electric machine mechanically coupled with an exhaust turbine of an E-Turbo of a vehicle or adjusting an engine power based on a speed of the exhaust turbine and an air-fuel ratio (AFR) of an engine of the vehicle of the engine responsive to the speed of the exhaust turbine increasing above a threshold turbine speed. By increasing or decreasing the power generated by the electric machine and/or adjusting the engine power, the temperature of the exhaust gas may be maintained within a threshold temperature range where an efficiency of an aftertreatment system may be maximized, thereby reducing an emissions of the vehicle.
