After yesterday's Porsche Boxster Spyder spy shots, the same WCF reader has sent us a batch of spy images with several 911 prototypes.

Porsche has been testing the facelifted 911 range for quite some time and now a crop of prototypes were spotted in South Africa ahead of what will likely be an official reveal in the second half of this year, possibly in September at the Frankfurt Motor Show. As you would expect from a 911 facelift, the changes will be very subtle and likely visible only to the trained eye but this shouldn’t come as a surprise since Porsche has a winning formula with the 911’s design so they won’t alter the recipe and risk losing loyal customers.

Aside from the minor visual tweaks, the facelifted 911 range could drop all the naturally aspirated engines, with the exception of the GT3 and GT3 RS models. Company’s product chief Wolfgang Hatz has already said this will eventually happen, but he didn’t specify an exact timetable so they might decide to wait until the next-gen likely due around 2018.

Chances are the 911 GT3 RS will be launched before the rest of the refreshed models and it will come with an all-new engine which will reportedly deliver somewhere in the region of 500 bhp (373 kW).

Special thanks go to Wood for sending us the pics!
