CONCORD, N.C. — William Byron overcame a pit road speeding penalty and passed Justin Allgaier in overtime to win Saturday’s NASCAR Xfinity Series race at Charlotte Motor Speedway.
It is his fifth career Xfinity victory and first since Phoenix in November 2017 — a span of 10 starts for the Cup Series regular.
The victory comes a day after Hendrick Motorsports announced it had signed Byron to a contract extension through the 2029 season.
“It just felt awesome to win here,” Byron said of his first national series victory at Charlotte Motor Speedway, his hometown track.
