These images are from March 27 and April 11 2014, where a 991 Turbo and a 991 Turbo S can be seen testing thoroughly on the Nürburgring Nordschleife. It might be development work for a 991 facelift coming up, or maybe some technology development for the upcoming GT2. Anyways, enjoy the video! © Touriclips 2014 Follow us on Facebook and Twitter as well! FACEBOOK: / touriclips TWITTER: / touriclips
