Racing career

Beginnings

Byron became interested in racing when he was six years old after seeing a stock car race on television, later attending a race at Martinsville Speedway in 2006. He began racing on the iRacing simulator as a teenager with over 100 wins and 298 top fives in online competition.

In 2012, he and his father explored how Byron could start racing offline, in real cars. He started racing Legends that year at the age of 15, relatively late for modern drivers. That year he won 33 races and became the Legend Car Young Lions Division champion.

For 2014, Byron signed with JR Motorsports late model program, in addition to continuing Legends competition. Byron competed in the No. 9 Liberty University Chevrolet at Hickory Motor Speedway in North Carolina for JRM. Byron scored a single victory and 11 top-five finishes, finishing second in points to teammate Josh Berry at Hickory.

K&N Pro Series

Byron was signed to drive in the NASCAR K&N Pro Series East for 2015 by HScott Motorsports with Justin Marks, with sponsorship from Liberty University. Byron also continued racing late models for JR Motorsports. In his debut K&N East in February at New Smyrna Speedway, Byron finished 7th. Byron won the second race of the season at Greenville-Pickens Speedway after starting second and leading all 152 laps (two laps past the scheduled distance). Byron made his ARCA Racing Series debut at Lucas Oil Raceway in July, driving the No. 55 Liberty University Toyota Camry for Venturini Motorsports. Byron finished second after leading 120 laps. He scored four K&N East wins en route to winning the series championship. Byron and his team also competed in the 2015 K&N Pro Series West races at Sonoma and Phoenix, finishing fifth and second respectively.

Craftsman Truck Series

On October 29, 2015, Kyle Busch Motorsports announced that Byron would run a full-time schedule in the team's No. 9 Toyota Tundra in the NASCAR Camping World Truck Series during the 2016 season. To prepare him for the run, KBM fielded the No. 9 for him in the 2015 Lucas Oil 150 at Phoenix International Raceway. Byron started the 2016 season on a low note crashing on the final lap at Daytona to finish 13th, and finishing 32nd at Atlanta after blowing an engine. Later, Byron would get his first top 3 and 10 in the Truck Series after finishing a strong 3rd at Martinsville. Byron won his first Truck Series race at Kansas in May, after avoiding Ben Rhodes and Johnny Sauter's crash on the last lap of the race, and took his second race win in Texas in June. He won the next race at Iowa, finished 17th at Gateway due to a crash, and won yet again at Kentucky, propelling him to first in points. He followed that up with his fifth win of the season at Pocono Raceway, breaking the Camping World Truck Series record for most wins by a rookie. The previous mark was held by Kurt Busch during the 2000 season with four wins.

During the playoffs, Byron won the first race of the Round of 8 at New Hampshire but suffered an engine failure at the last race of the Round of 6 at Phoenix, which cost him the chance to join the Championship 4. With a win at the final race at Homestead, he placed fifth in the overall standings, with a total of seven wins, eleven top 5s, and 16 top 10s in 23 races. In addition to clinching the owners' championship for the No. 9 team, Byron was named Rookie of the Year.

Byron returned to the Truck Series in June 2021, driving the No. 27 for Rackley WAR at Nashville Superspeedway.

On April 7, 2022, Byron drove the No. 7 for Spire Motorsports, giving the team its first Truck Series win at Martinsville.

On March 9, 2023, it was announced that Byron would return to Kyle Busch Motorsports for the first time in six years, driving the No. 51 at Bristol Dirt, Darlington, and North Wilkesboro.

Xfinity Series

On August 18, 2016, Byron and Hendrick Motorsports announced they had signed a multi-year driver contract, with Byron running full-time in the NASCAR Xfinity Series driving the No. 9 Chevrolet Camaro SS for JR Motorsports in 2017. Byron finished 2nd at Michigan, just losing out to Denny Hamlin. One week later, Byron won his first career race at Iowa after Christopher Bell wrecked late in the race, battling for a win with Ryan Sieg, who eventually placed second. He ended up winning again the week later in an overtime finish at Daytona. Byron also won at Indianapolis Motor Speedway for the third Xfinity victory of his career; he would add a fourth win when the series visited Phoenix for the penultimate race of the season. The Phoenix win also placed Byron among the four drivers eligible to race for the series championship at Homestead-Miami Speedway. At the final race in Homestead, Byron held off his Championship 4 teammate Elliott Sadler in the final laps to win the 2017 NASCAR Xfinity Series Championship.

In 2022, Byron returned to Xfinity series for the first time since 2017. He drove the JR Motorsports No. 88 to a second-place finish at Texas and 26th at New Hampshire. Driving the Hendrick Motorsports No. 17 at Watkins Glen, Byron fiercely battled Ty Gibbs for the lead throughout most of the race until they both spun off-course during the final restart, resulting in Byron finishing 25th.

In 2023, Byron returned to the No. 17 for a single race at COTA, finishing runner-up to A. J. Allmendinger.

On February 27, 2024, it was announced that Byron will drive the No. 17 in 4 races throughout 2024, with those races being at Phoenix, Darlington, Pocono, and Watkins Glen.

He was eliminated in the Round of 12 after the Kansas race.

Byron's victory started an eleven-race Top-10 streak, with Top 5 finishes at Martinsville, Talladega, Darlington and Dover. Byron's Top-10 streak would come at an end at the Circuit of the Americas road course, as he would finish 11th. Byron rebounded in the following race with a Top-5 finish at Charlotte in the Coca-Cola 600, finishing fourth. After finishing 35th at Sonoma Raceway following a wreck, Byron rebounded with back-to-back third-place finishes at Nashville Superspeedway and the first of a double-header at Pocono Raceway. Byron struggled the next four races finishing outside the Top 10, but would finish sixth at the 2021 Go Bowling at The Glen. During the playoffs, Byron made it to the Round of 12, but struggled with poor finishes at Las Vegas and Talladega. Following the Charlotte Roval race, he was eliminated from the Round of 8. He finished the season with a career-high 10th in the points standings.

During the 2022 season, Byron started with two DNFs at the 2022 Daytona 500 and Fontana, but rebounded with wins at Atlanta and Martinsville. On May 5, 2022, Byron received a contract extension to remain at Hendrick Motorsports through 2025. At Darlington, Byron was close to scoring his third win when Joey Logano punted him to the wall with two laps to go. On July 28, 2022, three days prior to the Indianapolis road race, the generator of the No. 24's hauler caught fire. The car was not damaged by the blaze. At the Texas playoff race, Byron spun Denny Hamlin towards the infield grass during a late-caution period; he was subsequently fined US$50,000 and the No. 24 was docked 25 driver and owner points. On October 6, 2022, the National Motorsports Appeals Panel rescinded the points penalty and instead amended the fine to US$100,000, placing Byron back to seventh in the playoff standings. Byron was eliminated following the Round of 8 after finishing eighth at Martinsville. He finished the season in a career-best sixth in the points standings.

2023: Breakout season

Byron started the 2023 season with a 34th place DNF at the 2023 Daytona 500. He later scored back-to-back wins at Las Vegas and Phoenix. On March 15, 2023, the No. 24 was served an L2 penalty after unapproved hood louvers were found installed on the car during pre-race inspection at Phoenix; as a result, the team was docked 100 driver and owner points and 10 playoff points. In addition, crew chief Rudy Fugle was suspended for four races and fined US$100,000. On March 29, the National Motorsports Appeals Panel amended the penalty, upholding the fine and Fugle's suspension but restoring the owner, driver, and playoff points. On April 6, the No. 24 was served an L1 penalty after alterations to the car's greenhouse were discovered during post-race inspection following the Richmond race; as a result, the team was docked 60 driver and owner points and five playoff points. In addition, interim crew chief Brian Campe was suspended for two races and fined US$75,000. At Darlington, Byron scored his seventh career win and the overall 100th win for the No. 24.

The win was the first Daytona 500 win for the No. 24 since 2005 by Jeff Gordon and the first Daytona 500 win for Hendrick Motorsports since 2014 by Dale Earnhardt Jr. It was also a special win because the win occurred 40 years to the date Hendrick Motorsports ran its first ever race as a team in the 1984 Daytona 500.
