Porsche's iconic vehicle remains the 911. It is so because it is a legend on the track. And one of the things that makes it fast on the track also makes the thing a bitch to drive if you don't know what you're doing - that is the rear engine and the need to stay on the gas or you'll spin the thing.
I understand the place in the lineup for a more affordable Porsche, even if that means putting the engine in the middle. The Boxster and the Cayman make sense because they're still fairly-no-nonsense sports cars without a lot of compromises. Having a mid-engine is a slight departure from history, but it's still a sports car, through and through.
Making a 4-door sedan with a front engine and slapping a Porsche badge on it is cynical, ostentatious, and stupid. I'm not saying that they should have put a rear engine in a sedan, I'm saying they shouldn't have made a sedan (or an SUV) at all. Porsche can do what they want and profit where they want to, but that doesn't mean that I won't think anyone driving down the road in one of these monstrosities isn't a giant douchebag.
