When you think of Porsche, you immediately think of the 911. If some folks had a choice, you would go to a Porsche dealer and all they would say to you is "what color 911 would you like?" and give you no other options. The 911 is Porsche's most recognizable and legendary car, but it isn't nearly their most important. That honor goes to the new Panamera E-Hybrid. And that's because I think it's the first car to fire a shot at the Tesla Model S.
