Regional brands
Badge engineering often occurs when an individual manufacturer (such as the regional Big Threes of the United States, Europe, and Japan) owns a portfolio of different brands and markets the same car under different brands and nameplates. The practice is used for multiple reasons. In one example, a company may do so to expand its range of different brands in a market without the cost of developing completely new models. In the United States, General Motors may sell a car through each brand; for example, the Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade each share a common body.
