Two Sedans with some similarities, but otherwise different in most aspects such as the starting price, horsepower, fuel economy, and maximum occupancy.

Also, although the 2017 Panamera has a more powerful engine than the 2017 Quattroporte, it gets 4.6 more mpg. And finally, you'll seat one more passenger in the Quattroporte than in the Panamera. Among similarities are the body structure, market segment, ground shadow size, and height.
