A powertrain unit for motor-vehicle (1) comprises a supercharged internal-combustion engine (2) and a transmission (5), which can be actuated by the internal-combustion engine (2) by means of a clutch device (6) of the dry type. The powertrain unit (1) further comprises a cooling system for cooling the clutch device (6) with a flow of air. The cooling system makes use of the supercharging compressor (3) of the engine (2) as source of pressurized air for supply of the flow of cooling air into the housing (60) of the clutch device (6).
