Kyle Sieg Bio
Kyle Christian Sieg (born April 16, 2001) is an American professional stock car racing driver. He competes full-time in the NASCAR O’Reilly Auto Parts Series, driving the No. 28 Chevrolet SS for RSS Racing, the family team owned by his father Rod Sieg. He is the youngest son of Rod and the younger brother of current driver Ryan Sieg and the late Shane Sieg.
A Georgia native, Sieg has built his career through the ARCA Menards Series ladder before stepping into NASCAR’s national spotlight. Racing out of a multi-car family operation has given him a steady development path and a long-term home in the second-tier stock car ranks.
Early Life and Background
Kyle Christian Sieg was born on April 16, 2001, in Tucker, Georgia, United States. He grew up in a household shaped by stock car racing, with his father Rod Sieg owning RSS Racing, a team that fields multiple entries across NASCAR’s development and national series. From an early age, Kyle was surrounded by the rhythms of a working race shop, and his brothers Ryan and Shane were already pursuing driving careers of their own.
The Sieg family has long been part of the Southeast’s short-track and stock car culture, and that environment shaped Kyle’s introduction to the sport. He began his own climb through the sport’s grassroots ranks while still a teenager, leaning on family guidance and the resources of his father’s team. That early grounding gave him a clear sense of the business side of racing alongside the on-track craft.
Path to NASCAR
Sieg’s path to NASCAR followed the ARCA Menards Series, a traditional development ladder for young American stock car talent. In 2020, he made his ARCA Menards Series debut with Cook-Finley Racing in the No. 42 Chevrolet at Lucas Oil Raceway, finishing tenth in his first start. That same year he added an ARCA Menards Series East start at Dover and ran the combined Bristol event, gaining valuable seat time in stock cars at a variety of track types.
In 2021, RSS Racing confirmed plans for Kyle to run the first four ARCA races of the season in the family’s No. 28, with hopes of stretching the schedule into a full year. He responded with top-ten runs in all four starts, including top-fives at Phoenix and Talladega. On May 12, 2021, the team announced his NASCAR Xfinity Series debut at Dover with DGM Racing in the No. 90 through an RSS partnership, formally launching his national-series career.
Kyle Sieg Career
Early Career (2020–2021)
Sieg’s first two seasons served as a structured apprenticeship. Driving for Cook-Finley Racing in 2020 and then the family team in 2021, he focused on consistency and finishing races on lead laps. Across his ARCA Menards Series East and main ARCA appearances, he regularly placed inside the top twenty while learning the rhythms of superspeedways, short tracks, and intermediates alike.
By the end of 2021, Sieg had recorded nine top-ten finishes in the ARCA Menards Series without a victory, establishing himself as a steady, developing talent. His Xfinity Series debut at Dover in May 2021, where he finished thirty-fourth after a late tire failure, was a learning moment that connected his development path to NASCAR’s national level.
NASCAR O’Reilly Auto Parts Series Breakthrough (2022–2023)
In 2022, Sieg moved into a part-time Xfinity Series schedule with RSS Racing, rotating through the team’s Nos. 28, 38, and 39 Ford Mustangs. He campaigned for Sunoco Rookie of the Year honors, and his tenth-place run in the Wawa 250 at Daytona International Speedway became his best finish of the season. Those results convinced the team to expand his role.
On February 1, 2023, RSS Racing announced Kyle would drive the No. 28 full-time for the 2023 Xfinity Series season. Over 31 starts he produced one top-ten, a seventh-place run at Atlanta Motor Speedway in the summer, and an average finish of 23.5, ending the year twenty-second in the championship standings. The schedule gave him a full season of seat time and exposure to every track on the circuit.
RSS Racing Era (2024–Present)
Sieg’s 2024 campaign featured both adversity and a memorable moment. After failing to qualify at Daytona, he battled through the year with the No. 28 team and was running near the top ten at Michigan late in the race when contact from Chandler Smith sent his car airborne. The No. 28 flipped, landed on its roof, slid along the inside wall, and somehow returned to all four wheels; Kyle climbed out uninjured. His race team sent the damaged car to NASCAR’s Research and Development Center to study the roof-flap performance, underscoring the seriousness of the wreck.
For the final five races of 2024, Kyle and his brother Ryan swapped numbers, with Kyle moving to the No. 39 and Ryan taking the 28 to help build owners points. The team confirmed Kyle would return to the No. 28 for 2025, keeping him in the seat as RSS Racing’s primary driver.
Driving Style and Strengths
Sieg’s strongest work has come at superspeedways and high-speed intermediates, where pack racing and positioning reward patience and timing. He has shown a willingness to race near the front in closing laps, as seen in his late-race run at Talladega in 2023. Working closely with the RSS Racing crew chief group, he continues to refine his race craft, fuel-mileage strategy, and restarts as his Xfinity Series tenure lengthens.
Notable Races and Milestones
His 2021 Xfinity Series debut at Dover, his top-ten run in the 2022 Wawa 250 at Daytona, and his seventh-place finish at Atlanta in 2023 each marked clear steps forward. The 2024 Michigan race, dramatic as it was, became one of the season’s most discussed moments because of the multi-flip sequence and the safety review that followed.
Kyle Sieg Career Wins
Kyle Sieg has not yet recorded a victory in the NASCAR O’Reilly Auto Parts Series or the ARCA Menards Series across his career. His results to this point are built around consistency, top-ten finishes, and steady seat time rather than trips to Victory Lane.
NASCAR O’Reilly Auto Parts Series Highlights
In 81 Xfinity Series starts through 2024, Sieg has recorded four top-ten finishes without a win or a pole. His first Xfinity race came in the 2021 Drydene 200 at Dover Motor Speedway, and his best championship result remains twenty-second in 2023. He has shown steady improvement in average finish and has put himself in position for late-race top-fives at drafting tracks.
Other Wins and Performances
In the ARCA Menards Series, Sieg posted nine top-ten finishes without a win, with a best series result of ninth in 2021. He added one top-ten in the ARCA Menards Series West across two starts, while his ARCA Menards Series East appearances produced a best finish of twenty-fifth in 2021. Across every stock car series he has entered, his résumé reads as a developmental success story still in progress.
Kyle Sieg Family
Family Background and Racing Lineage
Kyle is the youngest son of RSS Racing owner Rod Sieg, whose multi-car team fields entries across the ARCA Menards Series and the NASCAR O’Reilly Auto Parts Series. His older brother Ryan Sieg is a long-time Xfinity Series driver and a teammate within the family operation, while his late brother Shane Sieg also pursued a stock car racing career. The Sieg brothers represent one of the more active family-run programs in NASCAR’s second tier.
Personal Life
Sieg continues to live and work out of the family’s racing base in Georgia, close to the RSS Racing shop. Much of his daily life centers on the team, his brothers, and the demands of a full-time national touring schedule.
2025 Season Performance
The 2025 NASCAR O’Reilly Auto Parts Series season marks Kyle Sieg’s third full year in the No. 28 for RSS Racing and his second consecutive season with Chevrolet power after the team’s manufacturer switch. Building on a 2023 season that ended twenty-second in points and a 2024 campaign interrupted by the dramatic Michigan airborne crash, he entered 2025 focused on turning consistency into top-fifteen and top-ten runs on a weekly basis.
Through the early portion of the season, Sieg has worked to raise his average finish and return to the top of the midfield, leaning on the chemistry between the No. 28 team and the RSS Racing crew chief group. Track types that reward experience, including drafting venues like Daytona and Talladega and intermediates like Atlanta and Texas, remain priorities as he searches for his first career top-five.
Looking ahead, the goals for Sieg and RSS Racing are clear: contend for stage points, log clean finishes, and position the No. 28 team to make a run at his best career championship result. With family ownership, a familiar crew, and a full season of support behind him, 2025 offers Sieg his most complete platform yet to take the next step in NASCAR’s second tier.
