So many mistakes in so few words:
- The abbreviation VAG hasn't been used for over two decades.
- It only ever referred to a distribution subsidiary, not to the whole company.
- It's official spelling included dots: V.A.G
- The VW group itself hasn't been a 'GmbH' since 1960.
- GmbH is spelled with a capital H.
Sure, but those are different brands, you won't find the name Volkswagen on an Audi or even less so on a Lamborghini. These also aren't artificial brands, created by a PR department. They all used to be independent companies. And to use other examples from the auto industry, adding a higher-positioned brand worked out for Lexus, Infiniti, and Acura (at least in the U.S., much less so in Europe, Acura never even made it to Europe), it did not work out for Daimler with the Maybach brand, nor did introducing a higher-end model under the Volkswagen brand, the Phaeton, work out so great.
It's great that you think that there are zero risks involved with a change in strategy. Or maybe 'great' is not the right word and 'overbearing' describes your posture better.
