Walter Röhrl drives new Porsche 911 GT3, but…

…not at the Nürburgring.

Details of the the new 997.5 Porsche 911 GT3 were released the other day (see AUSmotive for more), and now a promotional video of the car in action has surfaced. As with other similar videos Porsche’s most famous test driver Walter Röhrl is at the wheel. However, perhaps crucially, the footage was not filmed showing the car in action on the Nordschleife.

Is this a sign the battle with Nissan has started to take its toll on Porsche?
