NASCAR Cup Series outfit RFK Racing has revealed three stunning throwback tributes to honor the late Greg Biffle at Darlington (March 22).

In recent history, Darlington Raceway has played host to the sport's annual throwback weekend, with teams running historic paint schemes and paying homage to some of the best NASCAR drivers to ever do it.

This year, NASCAR is not officially promoting throwback weekend, but teams will still be able to run throwback paint schemes if they wish to.

RFK Racing has chosen to do exactly that, honoring their former driver, who tragically lost his life in a plane crash in December, along with his wife Cristina, and two children, Emma and Ryder.

RFK Racing Greg Biffle throwback tributes

RFK Racing will run three different paint schemes on its three cars at Darlington, inspired by some of the most iconic cars that Biffle drove during his career.

The No. 6 Ford's throwback scheme incorporates fluorescent accent colors, much like many of the cars Biffle used during his career. Meanwhile, the No. 17 Ford throwback scheme pays homage to Biffle taking Cup Series pole at Texas in 2011.

Last but certainly not least, the No. 60 Ford scheme takes its inspiration from Biffle's primary paint scheme from 2009, including the Daytona 500 that year.

All three cars will also feature the distinctive No. 16 number style that Biffle used, just as they did at the Daytona 500 last month.

RFK President: We'll forever remember Biffle

"The memory of Greg Biffle's adventurous spirit, his fun-loving personality, and his endearing appreciation for his fans will forever be remembered and embraced by the NASCAR community,” said Team President of RFK Racing, Chip Bowers in an official statement.

“The three selected throwback color schemes showcased humbly by the No. 6, No. 17, and No. 60, represent incredible moments in Greg's storied career and offer fans, friends, and family alike an opportunity to reflect on the man and the competitor that we'll forever remember with fondness and reverence.

"Darlington Raceway, one of Greg's favorite track, serves as the perfect backdrop for all to relive his indelible impact on sport."
