What it takes to win at Charlotte

Charlotte Motor Speedway's surface is rough and bumpy. Sunday's Bank of America 500 opens the Round of 12 in the NASCAR Playoffs. Combine the challenging surface and aggressive post-season driving, and you have a situation where a win is difficult to come by. In this video, a few former winners at the track -- Austin Dillon, Kasey Kahne and Kevin Harvick -- tell all about the skill that's needed to navigate the 1.5-mile track that opens the second round of the Monster Energy NASCAR Cup Series Playoffs. "Charlotte's a challenge, but it's one of my favorite challenges we go to," Dillon said.
