ABSTRACT:
An automobile powertrain has at least an engine placed in an engine room and oriented so that its crankshaft is directed transversely, and a transmission placed in the engine room behind the engine. The transmission has input and output shafts arranged coaxially with each other and directed parallel to the crankshaft of the engine. An engine clutch is directly connected to the crankshaft, and a power transfer arrangement is disposed oppositely to the engine with respect to the engine clutch and operationally couples the engine clutch to the input shaft so as to transmit engine output to the transmission. The transmission, engine clutch and power transfer arrangement are independently accommodated in separate chambers of a single unit powertrain case. The transmission chamber and the power transfer chamber are connected to each other by an oil passage through which the input shaft extends from the transmission to the power transfer.
