A suspension system includes an engine and transmission assembly mounted transversely in a vehicle and having a main axis of moment of inertia extending in a left and right direction of the vehicle, a single first mount located at a first end of the engine and transmission assembly and at least one additional mount located in the vicinity of an opposite second end of the assembly. The center of gravity of the assembly is located on a main axis of moment of inertia of the assembly extending between the first and second ends and is closer to the first end than to the second end. The mount is a bushing-type mount and is oriented so that the central axis of the mount extends parallel to the main axis of moment of inertia of the assembly so that the mount supports the assembly in a front and rear direction of the vehicle to suppress rocking of the assembly during acceleration and deceleration. The mount has a soft spring characteristic in an up and down direction so that high frequency engine vibrations are prevented from being transmitted to the vehicle body.
