William Byron Profile, News and Results

William McComas Byron Jr. drives the No. 24 Chevrolet for the all-powerful Hendrick Motorsports team in NASCAR Cup Series racing.

Byron finished the 2025 season ranked fourth after a campaign which saw him grab three race wins and finish the regular season atop the standings.

William started the year in terrific fashion with a second consecutive Daytona 500 victory, and his win at Martinsville in October clinched a third straight Championship-4 berth. He is hanging around the rim right now, so close to clinching that elusive first title.

Byron’s task of course is made harder by the fact he races on the team as two-time champion Kyle Larson. It is tough at the top…

William announced himself on the Cup Series scene in style in 2018 as he claimed Rookie of the Year honors, having won the Xfinity Series title a year earlier in 2017. Just for good measure he also set a rookie Truck Series record of seven wins in 2016.
