Richard Childress Racing announced today that Austin Hill and United Rentals, the world’s largest equipment rental company, will return to NASCAR Cup Series competition for a limited schedule in 2025. In the first of five starts, Hill will drive the No. 33 United Rentals Chevrolet at the historic Darlington Raceway on April 6. Andy Street will crew chief the part-time entry and make his debut calling the shots in the Cup Series.
“I’m excited to compete in the No. 33 United Rentals Chevrolet again this year,” said Hill. “United Rentals has been a longtime supporter of my career and to continue that relationship once again at the top level of our sport is special. I’ve enjoyed my starts in the Cup Series so far and the goal is to keep learning every time I climb into the car. We have been strategic with adding new tracks to the lineup each season, which allows me to gain valuable experience. Racing for Richard at any level is an honor, but especially in the Cup Series. The focus remains on winning the Xfinity Series championship in November, but any laps in the Cup car are important for the future.”
United Rentals has an integrated network of over 1,600 rental locations in North America, Europe, Australia, and New Zealand. Headquartered in Stamford, Connecticut, United Rentals offers general, aerial, and specialty rentals to a customer base that includes construction and industrial companies, utilities, municipalities, and homeowners.
The 2025 campaign marks United Rentals’ fourth year of partnership with RCR, but the relationship with Hill has been a constant for over eight seasons. United Rentals and Hill have found success and earned victories together in both the Truck Series and Xfinity Series.
In addition to the primary races on the No. 33 Chevrolet, United Rentals will serve as an associate partner on both Austin Dillon’s No. 3 Chevrolet and Kyle Busch’s No. 8 Chevrolet throughout the 2025 Cup Series season.
“We are looking forward to racing with Richard Childress Racing and Austin Hill in the NASCAR Cup Series,” said Craig Schmidt, senior vice president of national accounts, United Rentals. “We have a shared culture of team work that really cements the partnership. We are excited to continue our support and give our customers unique experiences and a great team to root for.”
Hill, who has competed in at least one Cup Series event the last three seasons, made his series debut at Michigan International Speedway in August 2022, earning an 18th-place result in the No. 33 Chevrolet. Hill is a 19-time NASCAR winner, the 2020 Truck Series regular season champion, and the 2023 Xfinity Series regular season champion. The 30-year-old made his inaugural Championship 4 appearance in 2024 and captured his first victory of the 2025 Xfinity Series season in February to secure another Playoff run.
“United Rentals is not only a long-time supporter of Austin, but of our sport,” said Mike Verlander, president of RCR. “They have consistently and strategically used their partnerships to showcase their position as a leader in the equipment rental industry. We are proud to represent their brand once again this season and to have Austin back in the No. 33 Chevrolet. Our Xfinity Series program is designed to develop talent among drivers and crew members, and we are showcasing that progress.”
Before being promoted to the Cup Series program, Street spent the last three seasons as crew chief of Hill and the No. 21 Chevrolet in the Xfinity Series. Together, the duo advanced to the Playoffs each year and earned a total of 10 victories, including three consecutive in the season-opener at Daytona International Speedway. Street, a 20-year veteran of the Welcome, North Carolina-based company, is the winningest crew chief at RCR in the past three years.
Hill will compete in a total of five races, all carrying the United Rentals colors.
