Kyle Busch’s death continues to rock the NASCAR world
Busch was a two-time Cup champion and undoubtedly a future Hall of Famer. He had been in the Cup Series since 2004 and had 762 career starts with 63 wins.
The 41-year-old won the championship in 2015 and 2019 and had 234 wins across all three NASCAR national series.
Busch holds the all-time record for wins in both the NASCAR O’Reilly Auto Parts Series (102) and the NASCAR Craftsman Truck Series (69).

Busch’s 234th and final NASCAR victory came at Dover a week before his death, when he led 147 laps in a dominating Truck Series win.
“You never know when the last one is,” Busch said after the win.
Busch made his mark in NASCAR during his time with Joe Gibbs Racing, where he spent the majority of his career and won the two championships. He left JGR for Richard Childress Racing after the 2022 season and won three times during his first season.
Busch’s last Cup Series victory came in June 2023. While he struggled for most of this season, he started on the pole in February’s Daytona 500 and was coming off a season-best eighth-place finish four weeks ago at Watkins Glen.

Kyle’s 11-year-old son, Brexton, returned to the racetrack earlier this week for the first time since his father’s death.
Richard Childress Racing announced last month that Busch’s No. 8 would be permanently suspended unless Brexton would use it should he enter the series.
