Thing is, they don't make "those sports cars" anymore. The closest they came in recent history is limited edition 911 R. Cayman is now comes with a 4 cylinder engine. They are now faking engine noises in all cars they make. They switched to electric steering. 

So no, they are not just making these minivans on a side to make money. They also turned 911s into boulevard cruisers. No wonder old 911s now fetch as much as brand new ones. Only suburban moms buying what they are making these days.
