William McComas Byron Jr. was born on November 29, 1997, in Charlotte, North Carolina. His interest in racing began at age six after watching a stock car race and attending an event at Martinsville Speedway in 2006. Byron initially honed his skills on the iRacing simulator, achieving over one hundred wins and 298 top-five finishes online before transitioning to real cars at the relatively late age of fifteen in 2012. That year, he quickly found success in Legends car racing, securing 33 wins and becoming the Legend Car Young Lions Division champion. This early success laid the groundwork for his rapid progression in NASCAR’s various touring series.
In 2014, Byron joined the JR Motorsports late model program, competing at Hickory Motor Speedway and finishing second in points to teammate Josh Berry. His breakthrough continued in 2015 when he signed with HScott Motorsports for the NASCAR K&N Pro Series East, winning four races and ultimately claiming the series championship and Rookie of the Year honors. The following year, Byron moved to the NASCAR Camping World Truck Series with Kyle Busch Motorsports, where he set a rookie record with seven wins and earned the series’ Rookie of the Year title in 2016. He further solidified his reputation by winning the 2017 NASCAR Xfinity Series Championship and Rookie of the Year award, driving for JR Motorsports, where he secured four victories.
Byron’s journey to the NASCAR Cup Series culminated in 2018, driving the No. 24 Chevrolet for Hendrick Motorsports, where he was named Rookie of the Year. He earned his first Cup Series victory at Daytona in August 2020 and has since accumulated 15 career victories. Notably, Byron achieved back-to-back Daytona 500 wins in 2024 and 2025, a rare feat in the sport’s history, and was crowned the 2025 NASCAR Cup Series Regular Season Champion. His career is characterized by consistent performance, rapid advancement through NASCAR’s developmental leagues, and significant achievements at the highest level of stock car racing.
