Cup Series

Dale Earnhardt Jr. talked about racing at Charlotte after dark this week. “As late as it gets in the night, at this track,” he said, “The groove narrows up. It gets faster and faster on the bottom and there’s no time to be gained in trying to step up the race track or run the high line like you might during the afternoon. So, it’s a really fascinating race track in the middle of the day. But, as it gets darker and darker and cooler and cooler, the groove really shortens up. So you need to be in that top three, I think, to have a shot at it.”
