The NASCAR Xfinity Series is where future NASCAR Sprint Cup stars are born.
In honor of the four drivers remaining with a shot at the Xfinity championship -- points leader Chris Buescher, defending series champ Chase Elliott, Ty Dillon and Regan Smith -- Xfinity has released a video that reflects back on some of the series’ past champions: Carl Edwards, Brad Keselowski, Martin Truex Jr., Ricky Stenhouse Jr. and Clint Bowyer.
