Abstract
A power unit for an automotive vehicle includes an internal combustion engine, an electric machine electrically connected to electrical power storage arrangement, and a turbocharger comprising a first turbine located in an exhaust line of the engine. This power unit further includes a second turbine, located in an exhaust line of the engine and drivingly connected to the electric machine, and a transmission set. A first input/output of the transmission set is connected to the second turbine and a second input/output of the transmission set is connected to a crankshaft of the internal combustion engine. The transmission set has an adjustable speed reduction ratio between its first and second inputs/outputs.

A power unit for an automotive vehicle the unit comprising:
- an internal combustion engine,
- an electric machine electrically connected to an electrical power storage arrangement,
- a turbocharger comprising a first turbine located in an exhaust line of the engine,
- a second turbine located in an exhaust line of the engine, and drivingly connected to the electric machine, and
- a transmission set having a first input/output connected to the second turbine and a second input/output connected to a crankshaft of the internal combustion engine
- wherein the power transmission set is a triple input/output transmission set having a third input/output connected to the electric machine and has a speed reduction ratio between first and second inputs/outputs thereof that is adjustable by controlling the electric machine.
