It’s clear that Porsche didn’t want to mess with success, so the new third-generation Cayenne looks a lot like previous Cayennes. Softly rounded front fenders, gaping air intakes, a bulging hood, and the shape of the greenhouse are all clear Cayenne traits that have carried through. It’s slightly lower and narrower, but Porsche didn’t radically alter the formula. It could have, as the 2019 model is entirely new. No sheetmetal carries over, and the Cayenne is now on a new platform. At this point, though, changing the model into something completely different would make about as much sense as replacing the 911 with a front-engine sports car. (You laugh, but that almost happened—see 928.)
