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.
