Following the sudden death of NASCAR star Kyle Busch at the age of 41, the racing community has been flooded with tributes — including a deeply emotional message from the family of late driver Greg Biffle, who said Busch once played a crucial role in supporting them during their own tragedy.

Biffle’s family released a statement expressing shock and heartbreak over Busch’s passing, while also reflecting on the bond the two families shared through years in the NASCAR world.

“The passing of Kyle Busch is incredibly difficult to comprehend,” the statement read. “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 family went on to describe Busch as “larger than life,” emphasizing both his competitive nature and the close friendship he shared with Greg Biffle over the years.

“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,” they said.

Greg Biffle, 55, along with his wife Cristina, 35, their five-year-old son Ryder, his 14-year-old daughter Emma, and three others, died in a plane crash on December 18, 2025. Their Cessna Citation 550 went down while attempting to return to Statesville Regional Airport in North Carolina.

Since that tragedy, the Biffle family said Busch and his loved ones remained close, spending time together in the off-season and watching their children grow while continuing to support one another through grief and life changes.

Now, they say they are returning that same support to Busch’s family in the wake of his sudden death.

“It’s hard to imagine our racing community without Kyle,” the statement continued. “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.”

Busch’s death came after what reports described as a period of respiratory issues. According to 911 call audio, a man assisting him said Busch was coughing up blood and struggling to breathe before he was taken to hospital on Wednesday night.

On Thursday evening, Busch’s family, Richard Childress Racing, and NASCAR confirmed his death in a joint statement.

“Kyle was fierce, he was passionate, he was immensely skilled and he cared deeply about the sport and fans,” the statement read. “Throughout a career that spanned more than two decades, Kyle set records in national series wins, won championships at NASCAR’s highest level and fostered the next generation of drivers as an owner in the Truck Series.”

As the NASCAR world continues to mourn, the connection between the Busch and Biffle families has become a powerful reminder of the close-knit relationships within the racing community — and how deeply one loss can ripple through it all.
