Since the Cayman GT4s "official" introduction a few weeks ago, we've been learning more and more about its track capabilities. One of our best sources of information came from Chris Harris when he compiled his full, on-track review in this video. However, that's not to say there isn't more to learn or more to see. Today's video, while admiteddly a bit more dry than those of Harris' making, features none other that Porche's Walter Röhrl. Watch along as he plays with the GT4 on the track and gives his first person feedback on what makes it Porsche's newest track monster.
