For each of its seven generations the engineers in Zuffenhausen and Weissach have reinvented it, time and time again demonstrating to the world the innovative power of the Porsche brand. Like no other vehicle, the 911 reconciles apparent contradictions such as sportiness and everyday practicality, tradition and innovation, exclusivity and social acceptance, design and functionality. It is no wonder that each generation has written its own personal success story. Ferry Porsche best described its unique qualities: "The 911 is the only car you could drive on an African safari or at Le Mans, to the theater or through New York City traffic." In addition to its classic yet unique lines, the Porsche 911 has always been distinguished by its advanced technology. Many of the ideas and technologies that made their debut in the Porsche 911 were conceived on the race track. The 911 was committed to the performance principle from the start, and motor racing is its most important test lab. From the very beginning it has been at home on circuits all over the world, earning a reputation as a versatile and dependable winner. Indeed, a good two thirds of Porsche's 30,000 race victories to date were notched up by the 911.
