William Byron was the fourth driver to qualify for the Championship 4, and he was the only one to qualify based on points. The driver No. 24 Chevrolet Camaro ZL1 for Hendrick Motorsports endured some really tough conditions to qualify.
Byron finished 13th in the Xfinity 500 at Martinsville Speedway on Sunday. That was enough for him to finish eight points ahead of Denny Hamlin for the final spot in the Championship 4. Kyle Larson, Christopher Bell and Ryan Blaney all qualified by winning races.
Temperatures were hot at Martinsville over the weekend, and Byron had lots of difficulty keeping his helmet cool during the 500-lap race. Byron battled poor vision over the last 60 laps on Sunday because he was struggling to keep cool.
