An engine positioning structure is used for a rear wheel drive automobile, with an engine mounted in an engine compartment driving the rear wheels. In the automobile having a passenger compartment and the engine compartment, where the two compartments are separated by a dash panel, the engine is positioned so that a rotation axis of the engine is at a position higher than the height of a floor panel of the passenger compartment, and a rear end part of the engine is positioned behind a general plane defined by a position corresponding to the position of a passenger relative to a dash panel. The engine positioning structure enables a retreated layout of the engine to be obtained. It also reduces Yaw moment of inertia, and improves the steering stability.
