We've known for some time now that Porsche was reviving the classic Targa top style of past 911s in favor of the sliding glass roof option that was offered in more recent years. The 2015 Porsche 911 Targa is basically a carry-over of the current car, complete with the same engine options and other specs. The obvious main difference being the new retro style roof and silver-painted B-pillars. The official reveal is expected imminently. In the meantime these leaked images will have to suffice.
