Because Shanghai Volkswagen obtained the exclusive production and sales rights of the B5, Passat's name was directly translated from the original name "passat", and then North Volkswagen, that is, FAW-Volkswagen obtained the production rights of the B6. In order to distinguish and separate the two without having to pay trademark fees, it was named "Maotan". In fact, there are too many such examples in China, especially some Volkswagen cars from the north and the south. They are actually the same car, but they are of different ages and have different technologies.
