Zusammenfassung:	A connecting rod and methods for making the same are disclosed. A method of making a connecting rod may include joining a first connecting rod blank and a second connecting rod blank together. The first connecting rod blank includes a first material, while the second connecting rod blank includes a second material different from the first material. The first and second connecting rod blanks have an interface between the piston pin and crankshaft ends. The method further includes narrowing a cross-section of the blanks at the interface, forming a piston pin aperture in the first connecting rod blank, and forming a crankshaft pin aperture in the second connecting rod blank. At least one of the narrowing and forming steps works a perimeter of the interface, thereby forming a generally smooth connecting rod surface about the perimeter of the interface.
