How Greg Biffle's Family Is Honoring NASCAR Driver Kyle Busch After His Death
The family of late NASCAR driver Greg Bifle has offered its support to Kyle Busch's family, one day after Busch unexpectedly died at age 41.
Roush Fenway Keselowski Racing is in the midst of its annual Fan Day celebration in Charlotte, North Carolina. Part of that is a memorabilia sale, with a portion of proceeds meant to go to the Biffle Family Legacy Impact Fund. The fund, however, shared a statement via its Instagram Story, announcing a change in plans.
"All money raised today at RFK Fan Day will be donated to the Bundle of Joy Fund in honor of Kyle," the statement read. "He was dedicated and selfless in his support of Samantha and their dream to help other families. We want to honor their mission, which we know all too well, does not end here."
The Samantha and Kyle Busch Bundle of Joy Fund "is dedicated to advancing access to in vitro fertilization (IVF) care and coverage, increasing awareness and providing support," according to its website. Kyle and his widow, Samantha Busch, started the fund after struggling through their own fertility journey.
The couple shared son Brexton, 11, and daughter, Lennix, 4, both of whom were conceived via IVF.
Samantha, 39, opened up about her and Kyle's fertility struggles, which included a "very sudden miscarriage" in a July 2025 episode of the "Unlocked with Savannah Chrisley" podcast.
"We had a lot of marital struggles because we had never dealt with something so heavy and we didn't understand how each other were grieving and we didn't understand what each other needed in that time and place, so it was a struggle," she explained "So we worked on it. We worked really hard. We went to marriage counseling."
Samantha continued, "I just had this immense guilt and I was so mad at myself for it. Kyle, on the other hand, he was like, ‘You know, I'm not trying to sound cold, but it's done. There's nothing that you can do to change this outcome. We have to keep moving forward.'"
Kyle died on Thursday, May 21, after being hospitalized the day before with what his family called a "severe illness." The Associated Press later reported that the NASCAR Cup Series driver was found "unresponsive" in a racing simulator at Charlotte Motor Speedway.
It was the second unexpected death to rock the NASCAR world in the past six months, after Biffle died in a plane crash in December at age 55.
"The passing of Kyle Busch is incredibly difficult to comprehend," the Biffle family said in a statement shared via Facebook on Thursday. "First and foremost, we are praying for Sam, Brexton, Lennix, Gaye, Tom and Kurt. They stood with us through our own grieving just five months ago, holding our hand at the service and continuing to offer support and love. A loss like this is unimaginable for any family, and our hearts ache for them."
The statement continued, "Kyle was larger than life-iconic, fiercely competitive and an amazing friend to Greg. They leaned on each other often, not only through racing, but through life and personal challenges as well. Greg and Kyle spent time together in Glamis during the offseasons, enjoying watching their boys together and always looking ahead to the future with excitement and pride.
"It's hard to imagine our racing community without Kyle," the family concluded. "The impact of this loss will be felt far beyond the racetrack. We love the Busch family and will be here for them in any way they need."
