The reason behind the continued success of the Porsche brand lies in the name brand. Porsche vehicles were initially established as a sleek, beautiful, yet simple machine that performed exactly the way the consumer wanted it to. They combined innovation with tradition. Porsche has been so successful throughout its years because they were able to maintain that image throughout their new models. An example of this is the new Porsche Cayenne.
In the past Porsche has produced approximately 600,000 Cayennes, and each time they have reinvented their ideas of tradition and innovation within the SUV. Porsche started as a performance vehicle maker who had great success in motor-racing back in 1964, and built on that success to build performance street cars. This was their PoP(Point of Parity) that got the recognition in the automotive industry. Nowadays Porsche is know for it practical, yet fun vehicles that fit the needs of the wealthy family man. Porsche has many models, none being as practical as their Macans(SUV), Cayennes(SUV), and Panameras(Sedan); which can produce up to around 550 horsepower depending on the engine type. These PoD(Points of Difference) are what make Porsche stand out in their category and have made their brand so successful in past years.
