Jonny Lieberman explores the aspects of the all-new, second-generation four-door from Porsche. The facts of the car are (of course) impressive: 550 hp from a 4.0L, twin-turbo V-8, coupled with a new eight-speed PDK transmission that powers all four wheels, and all-wheel steering, which means the big Porsche is a serious performer. Since the Executive model gets a near–6-inch stretch, it’s easy to declare the Panamera the world’s ultimate factory limousine. However, is this the sedan Porsche should be building? To answer this question, Lieberman travels 89 years into the past and has a look at what might have been. What does he discover? Watch and find out!
