The
United Rentals 300 is the first race of the
NASCAR O'Reilly Auto Parts Series season, held at
Daytona International Speedway. It is held the day before the
Daytona 500, and is considered the most prestigious event of the O'Reilly Series. Until 2002, it was the only event of the O'Reilly Series to be annually held at Daytona International Speedway.
Austin Hill is the defending winner of the event.
History In 1959, the new 2.5-mile
Daytona International Speedway hosted its first O'Reilly Series event. It was scheduled the day before the Daytona 500, and ran a distance of either 200 or 250 miles. In 1966, the race became known as the
Permatex 300, making it only the second race on the NASCAR schedule to be named for a corporate sponsor. In 1968, the Permatex 300 was shifted from the Modifieds division to the newly organized NASCAR Late Model Sportsman Division. In 1982, the Late Model Sportsman Division was reorganized into the modern day NASCAR O'Reilly Auto Parts Series, and the race was sponsored by
Goody's for several years.
Incidents In the 1970s and early 1980s, the race was often ridiculed and exploited by local media for its frequent crashes and massive pileups. Several major accidents and fires over the years were blamed on the low level of experience by several of the drivers, and the older equipment used. The level of prestige held by the event, along with the relatively large purses, attracted numerous independent and one-off entries, contributing to the inexperience of drivers in the field. By the time the race had become part of a NASCAR touring series race, NASCAR tightened driver eligibility requirements, and the number of incidents has drastically been reduced. Under current NASCAR rules, drivers must be cleared to race at Daytona,
Talladega (added to the second tier series in 1992), and
Atlanta (after the 2022 redesign) requiring enough experience at intermediate tracks to be cleared by NASCAR to participate at Daytona. Drivers who intend to run the 300 or the
Truck Series Fresh From Florida 250 are required to participate in other lower-tier shorter support races, whether it was the former Dash Series race (which ended after 2004—it used less powerful cars) or until 2020, the
ARCA race the week prior to gain NASCAR clearance, especially if a driver has turned 18 after the preceding October
Talladega Craftsman Truck Series race (the ARCA race was moved to the Xfinity race day in 2021). NASCAR will also mandate the driver to participate in the January ARCA test at Daytona prior to the ARCA race or any national series race they intend to enter at Daytona, Talladega, or Atlanta during a season before they are allowed to participate in an ARCA or national series race at those circuits and there are no intermediate tracks beforehand. The 1960 race is notable for having the
largest pileup in NASCAR history. On the first lap, 37 cars crashed in turn four (out of a starting field of 68). In 1981 and 2004, the race started on Saturday, but was halted by rain, and finished Monday, the day after the Daytona 500. The 1969 race was red flagged three times for rain and also saw the fatal crash involving
Don MacTavish, which his whole front of the car ripped off. The 1979 running was shortened by rain and won by
Darrell Waltrip. A brutal crash erupted off Turn Two where fire exploded from the
Marion Cox Mercury of
Joe Frasson; driver
Don Williams was gravely injured in the crash and would die ten years later from the incident. The
2013 race featured two large accidents. With five laps remaining,
Michael Annett and
Austin Dillon collided and a multi-car crash erupted in the first turn. The race was halted as a red flag was given to clean up the debris. Annett was hospitalized overnight after sustaining bruises on his chest, but was released the following day in time for the Daytona 500, but was ruled out for the following race at
Phoenix because of a sternum injury. Following the red flag the race had two laps remaining.
Regan Smith and
Brad Keselowski moved into the lead on the final lap, but off the fourth turn, Keselowski turned Smith into the wall head on, causing the field to pile in.
Kyle Larson had the most significant impact, as his No.32 Chevrolet flew into the tri-oval
catch fence, causing its nose to snag a crossover gate, which tore open. The force of the collision dug the engine in, ripping it out of the car. The car's entire front half disintegrated and one front wheel lodged onto the engine and another flew approximately ten rows into the grandstand, injuring 30 spectators (two in critical condition). A total of twelve cars were involved in the crash, but all were unharmed. The two spectators that were seriously injured by the debris from Larson's crash were treated at the nearby
Halifax Medical Center and were later released. In 2015, two cautions in the final forty laps were caused by separate collisions that included eleven cars. In the first collision,
Regan Smith's car flipped over once in the tri-oval, while in the second collision,
Kyle Busch collided into a concrete wall head on, suffering a fracture in his leg and foot.
Ryan Reed would win the race, the first race under the Xfinity banner. As a result of his injuries, Busch was forced to miss the first 11 races of the Sprint Cup Series season however he would still manage to win the
season championship. The 2018 race produced the closest finish in any of NASCAR's top three series, when
Tyler Reddick edged
Elliott Sadler by 0.0004 seconds, making it the closest finish in NASCAR history. Since NASCAR scoring and timing does not measure beyond thousands of a second, the margin of victory was officially listed as 0.000 seconds (with video review which declared Reddick the winner by less than three inches). Analysis after the race by NASCAR timing and scoring officials placed Reddick's margin of victory at 0.0004 seconds. This race also had a record five overtime finishes, extending the race length to 143 laps. From 2019–2020, the race was known as the
NASCAR Racing Experience 300. On the final lap of the
2022 Beef. It's What's for Dinner. 300 (under the National Livestock and Meat Board sponsorship, the event was also alternatively known as "Beef 300" in NASCAR media),
Myatt Snider flipped into the catchfence coming into turn 3 at
Daytona International Speedway on February 19, 2022. The driver of the 31 TaxSlayer Chevy walked away from the crash. This gave former
NASCAR Camping World Truck Series driver
Austin Hill his first career
NASCAR Xfinity Series win. Hill would win the race again in 2023 and 2024, before his teammate
Jesse Love ended Hill's streak in 2025.
