Why does everyone seem to assume this is specific to VW in particular. They nay have been the most egregious but I would be surprised if this was isolated. Just look a those EPA mpg estimates, everybody seems to game the system and "tune" their cars to get highest ratings. Does anybody still hope to get anywhere near the estimate when buying a new car, especially city mpg? I would argue this sort of manipulation is done widely and was pretty well known and accepted but VW must have overdone it. Of course Diesel cars have potential for worse emssisons than gas but I bet this happens across the board, except the Germans are screwed because they are pushing Diesels.
