For a brief moment, the Porsche 911 GT3 RS was one of the quickest cars to ever lap the Nurburgring thanks to a time of 6:56.4. But around The Grand Tour test track, the Porsche wasn’t nearly as quick. At 1:20.4, the GT3 RS is the eighth fastest car on this list. The 520-horsepower coupe was piloted by American driver Mike Skinner.
