The Ambetter Health 400 is a NASCAR Cup Series stock car race held at Atlanta Motor Speedway in Hampton, Georgia. Daniel Suárez is the defending race winner.

This race was originally Atlanta's second race of the season and was run as a late-season event for much of its history. From 1987 until 2001, the race was scheduled in November as the final race of the NASCAR season. From 2002 until 2008, the race was moved to October in favor of awarding the final race weekend to Homestead-Miami Speedway and became part of what is now the NASCAR Chase for the Championship in 2004. In 2009, Atlanta swapped fall race dates with Auto Club Speedway and the race was moved to Labor Day weekend. From 2011 to 2020, this was Atlanta's only Cup Series race date as its spring race was moved to Kentucky Speedway and run later in the year.

In 2015, the race lost its place as the Labor Day weekend race for the Cup Series and became the second race of the season (after the season-opening Daytona 500). In 2020, it was moved from being the second race of the season to being the first race after the west coast swing (the races at Las Vegas, Phoenix and Fontana), making it the fifth race of the Cup Series season. However, the race would end up being run in June that year due to the COVID-19 pandemic (and it was the first Cup Series race to be postponed due to the pandemic). In 2021, the race was held as scheduled in March as the fifth race of the season.

History

From 1987 until 2001, the race was scheduled as the final race of the NASCAR season, and thus was typically the event in which the champion was decided. Several times, however, the championship had already been clinched prior to this race, rendering the race anticlimactic. In some cases, the championship would be decided the moment the points leader took the green flag to start the race – effectively clinching enough championship points by finishing last or better. Other times the championship might be decided early or mid-race, well before the checkered flag. For instance, in the 1993 race, Dale Earnhardt needed to finish 34th or better to mathematically clinch the championship. On lap 117 of 328, eight cars had dropped out of the race (including teammate Neil Bonnett in an intentional start and park). That meant Earnhardt could finish no worse than 34th and had effectively clinched the title before the race had reached the halfway point.

The 1992 race marked the final race for Richard Petty, and coincidentally, the debut for Jeff Gordon. With six drivers eligible for the Winston Cup Championship, the race is widely regarded as one of the greatest NASCAR races of all time. Alan Kulwicki, who finished second in the race, edged out Bill Elliott, the race winner, by leading one more lap in the race. Kulwicki won the NASCAR Winston Cup title by a then-record margin of only 10 points.

The 1998 race was run mostly at night after a long rain delay; despite the inexperience with the lights, newly installed for an Indy Racing League race, NASCAR and the teams agreed to attempt finishing the race at night. It was shortened to 221 laps because it was after 11:00 p.m. EST and NASCAR wanted to "get the fans out at a decent hour". The 1999 Cracker Barrel 500 also ended at night. This would mark a springboard of sorts at finishing delayed races at night by utilizing a track's permanent lighting system.

In 2001, the race was scheduled as the season finale, however, it ended up being the second-to-last race. The New Hampshire 300 was postponed from September 16 to the Friday after Thanksgiving, due to 9/11. Beginning in 2002 the race was moved to mid-October as NASCAR elected to hold its final race at Homestead-Miami Speedway instead of Atlanta. The 2003 race started a tradition of night qualifying at Atlanta, which has carried over to the spring race as well.

In 2006, the race start time was changed from 12:40 pm. EDT to 2:55 pm. EDT to finish the race at night. Driver complaints erupted because of the track's troublesome situation where the sun can get into the driver's eyes in Turn 1, including leading to a crash during the time the sun sets in that area of the track between Jeff Gordon and Jamie McMurray, led to the abandonment of the 3 pm start after this race.

During the race's history as the second in Atlanta, it had been rumored to be either eliminated or moved several times in recent years. On February 29, 2008, it was reported that Bruton Smith, the president of the track's owner, Speedway Motorsports, was talking with International Speedway Corporation (the owner of numerous other NASCAR tracks) about a possible date switch for 2009 with one of its tracks. He proposed a move that involved the fall Atlanta race and the Pepsi 500, the Labor Day weekend race held at Auto Club Speedway.[1] Doing so would give the Fontana, California track a race in the Chase for the Championship and also make the three races that precede the beginning of the Chase closer to each other geographically. Prior to the realignment, the teams raced in the Sharpie 500 at Bristol the week before Labor Day, then traveled cross country to California for the Pepsi 500, and then came back across the country to run the Chevy Rock & Roll 400 at Richmond the following Saturday. Smith's offer to have Atlanta as the Labor Day weekend race was accepted and was officially announced by NASCAR on August 19, 2008.[2] However, instead of moving the race at Auto Club Speedway (previously on Labor Day weekend) to Atlanta's spot on the schedule at the end of October, the AMP Energy 500 at Talladega Superspeedway was moved to that spot after previously being at the beginning of October, and the aforementioned Pepsi 500 was moved to the beginning of October in Talladega's old spot.

In 2015, Atlanta's lone race date moved to the second week of the season in early March, with the Bojangles' Southern 500 at Darlington Raceway returning to its traditional Labor Day weekend date. Atlanta will be run on a Sunday afternoon. This event used to be called the Oral-B USA 500, and this event used to be aired on ESPN for 6 years preceding the Irwin Tools Night Race at Bristol Motor Speedway and the Federated Auto Parts 400 at Richmond International Raceway[3]

On July 10, 2022, the track announced that Ambetter would be the title sponsor of the race starting in 2023. The company, owned by Centene Corporation, was the title sponsor of the Xfinity Series race at New Hampshire (another Speedway Motorsports-owned track) in 2021 and the Cup Series race at New Hampshire in 2022.[4] QuikTrip, one of the two title sponsors of the race since 2015, announced prior to the 2022 race that it would be their last year as title sponsor. Folds of Honor, the other title sponsor of the race, also did not return in 2023 as their title sponsorship was as a result of a partnership they have with QuikTrip.[5]
