There are a few cool aspects about this video. Firstly, this impressive lap time (7:37,9) is set by a stock Porsche Carrera S (imagine what the forthcoming 911 Turbo might do). Secondly, the usually busy Nordschleife has no other traffic on it for the purposes of this timed run. Thirdly, Porsche has been kind enough to include all the telemetry, including G-meter and circuit map. And fourthly, we get to watch the driver, Timo Kluck, in action during the lap.
To put this lap into perspective, in 2008 Porsche managed a 7:38 in its 997 911 Turbo. Timo Kluck was also behind the wheel of the 911 GT2 RS that did a 7:18 in April 2008.
