Latest shots get an up-close look at the next 911's new adjustable rear spoiler and new rear end design.

Here are the latest spy shots of the next generation 2012 Porsche 911 code named 991.

This prototype has been spotted with little camouflage, something we've previously seen. But here we get a much better look at that new rear spoiler that the 911 is sporting.

We get to see the shape of the adjustable rear spoiler close up in this set of shots and how it relates to that new rear end design. The prototype comes with a green number tag between the taillights, still partly masking the rear design change. But the pics give us the best sense we've had so far as to the next 911's new rear end look.

This is Porsche and change is subtle.

We can expect the 2012 Porsche 911 to debut sometime next year.
