Abstract
Abstract A mounting arrangement for an automotive vehicle includes a transverse engine having a crankshaft with an axis of rotation extending transversely to a longitudinal axis of the vehicle, a gear train of a transmission having an axis which extends in parallel with the axis of the engine crankshaft, and a differential gear unit having an axis which extends in parallel to the axes of the engine crankshaft and the transmission gear train. The axis of the engine crankshaft is located rearward of the axis of the transmission gear train and over the axis of the differential gear unit, and the axis of the differential gear unit is located rearward of the axis of the transmission gear train. Further, the engine to lower the engine hood line inclined forward.
