It's been nothing but bad news for the Nürburgring lately, but a small bright spot would be the addition of a two-lap Nordschleife race for the World Touring Car Championship. Still just an idea, but an awesome one.
They normally run approximately 50-52 miles based on their calendar. [www.fiawtcc.com] That translates to roughly 82km. They would need to run a 4 lap race to get in that kind of a window. I do agree with the commenters who are saying it needs to be longer, but 10 laps would be 2.5 times normal race distance for this series.
