A hybrid drive unit (10) for a motor vehicle with an internal combustion engine (12) and at least one electric machine (14) optionally operable as a motor or as a generator, has a charge air compressor (22) for compression of combustion air supplied to the internal combustion engine (12) and a charge air cooler (32) for cooling the combustion air. The hybrid drive unit (10) has a low-temperature cooling circuit (38) carrying a liquid coolant and is designed separately from a high-temperature cooling circuit of the internal combustion engine (12) and has a heat exchanger (42) for cooling the coolant, whereby the low-temperature cooling circuit (38) includes the charge air cooler (32) and the electric machine (12) and/or electronic components (34, 36) allocated to the electric machine (14). |
