Excerpt from the Panamera press release:
Clockwise from top left: the 2017 and 2014 Panameras with the 2016 911 Carrera 4S, bottom, provided as a comparison.
As evident from the images above, Porsche's press release is spot on. The new Panamera gets rid of the old model's ungainly hunchback shape, with the rear LED light bar, together with the sharply creased tail and upper bumper, developing a clear link to the 911. As per Porsche's press release, the new model creates a clearly defined identity as a sports-oriented GT, improving significantly upon the elephantine, confusing oddity that was the previous model.
