Could this be a form of concept car for Apple to test hardware/software on without any real intention of making their own car?
Maybe it's a demonstration platform to show partners what a well integrated system could feel like. Perhaps Apple wants to make the guts of the car control/infotainment system instead of just projecting an image over the OEM system.
Early reports on CarPlay from various vendors said that they varied widely in hardware speed/quality (I believe Ferrari's was said to be pretty bad). Apple doesn't like relying on third parties for their user experience (see: Moto ROKR).
This doesn't square with the report that says they are looking at manufacturing processes and materials. I agree with you though that this is the most likely explanation.
