When the Panamera was introduced in 2009 it had everything you would expect in a four-door sedan from Porsche (even if you never expected the legendary performance car company to build a four-door sedan). For 2017, everything but the concept and the Porsche badge have been updated. In the turbo model, you get an all-new turbo-charged V8 that makes 550 horsepower with only minimal boost. Make no mistake, this is a luxury sedan that can remove all but the nastiest road failings from your driving experience. And once you engage the Sport settings, it becomes a formidable sports car. This is a true evolution of the Panamera that represents a new definition of what a super-sedan can be.
