Thermal management systems for a vehicle powered by internal combustion engines (ICEs) are provided. Systems include a coolant circuit configured to circulate a coolant and transfer heat between the coolant and a heat consumer appurtenant to the vehicle, and a refrigerant circuit configured to circulate a refrigerant such that the refrigerant is capable of extracting heat from exhaust gas generated by the ICE and subsequently transferring heat to the coolant. The refrigerant circuit can include one or more of an exhaust gas heat exchanger, a compressor, a coolant heat exchanger, a condenser, and an evaporator. Heat transferred to the coolant via the coolant heat exchanger can be transferred to one or more heat consumers, including the ICE, a turbocharger, an oil heater, a heater core, an exhaust gas recirculation cooler, an axle, a differential, an exhaust gas treatment device, and a reductant reservoir for an SCR or SCRF device.
