A few months ago, there was a Porsche prototype caught testing that looked to be a Targa model disguised by a convertible top. At that point, we all though that Porsche was bringing back the famous fixed Targa roof option for the new generation 911. However, according to Autoevolution, this may not be the case after all. They are quoting a Porsche insider saying that "the car maker is considering selling the new glass roof model as a special Carrera rather than a Targa."
More than likely, Porsche took the public’s level of interest into account and decided that the Targa would be better off as an option as opposed to a full blown model. That would mean that this version would still get both rear-wheel drive or four-wheel drive configurations and the engines from both standard 911 Carrera and Carrera S models.
Previous rumors suggested that the 991 generation Targa would arrive in 2013 as a 2014 model, so we expect the new Targa option to have the same timeline.
