The name Interestingly, the car that we today know as the 911 was initially named the 901 (901 being its internal project number). However, the rival company Peugeot objected to the name on the ground that they had an exclusive right to name cars with three digits and the middle digit being 0. Although these rights were only valid in France, Porsche renamed the line of cars to 911 to avoid any complications. Thus was the name for one of the most popular automobiles in history selected; as a compromise.
