Apple, as I mentioned earlier, has always been clear about what can be included in its brand family and why its sub-brands (iPhone, Apple Air, and Apple TV) communicate strong family values of creativity, individuality, and elegant design. Some feel that Porsche has undermined its brand position as the ultimate sports car with the brand extensions of Cayenne SUV and Panamera luxury sedan, but it took this highly analyzed step after studying existing users and realizing that sports car buyers don’t buy a new model very often, yet luxury SUV and luxury sedan customers buy a new model every 2-3 years. Porsche made the sound business decision to reposition from sports cars to luxury cars and is now the number one luxury brand in the world. They gave up a little to gain a lot, but they were fully aware of the consequences on their brand positioning each step of the way. It didn’t take this major step on a whim, but by looking closely at who was buying their brand and who was not…and why for each. Brands aren’t religions, their tools to help you sell more stuff, to more people, more often, for more money as my old boss at Coca-Cola, Sergio Zyman, used to remind us. Porsche did exactly that and is a more powerful brand a more profitable company by doing so. Imagine where Apple, the most valuable company in the world would be if they would have strictly kept their brand only in personal computers.
