Rebranding is also known as "rebadging" and "badge engineering"; the latter is an intentionally ironic misnomer, in that little or no actual engineering takes place. The term originated with the practice of replacing an automobile's emblems to create an ostensibly new model sold by a different maker. Changes may be confined to swapping badges and emblems, or may encompass minor styling differences, as with cosmetic changes to headlights, taillights, front and rear fascias and outer body skins. More extreme examples involve differing engines and drivetrains. The objective is "to spread the huge development costs of a new vehicle over as many cars as possible." An example is General Motors' rebadging of the Camaro as the Firebird, a successful model from the 1970s through to the 2000s. In most cases, consumers are interested on each brand's focus "on the unique elements of styling and driving characteristics." Some cars would not be marketed without the cost savings that are obtained from this practice and carmakers can develop many "different models — all wearing different badges — off the one platform."
