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

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.

Kulwicki won the NASCAR Winston Cup title by a then-record margin of only 10 points.

This would mark a springboard of sorts at finishing delayed races at night by utilizing a track's permanent lighting system.

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.

Smith's offer to have Atlanta as the Labor Day weekend race was accepted and was officially announced by NASCAR on August 19, 2008.

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[4] On July 10, 2022, the track announced that Ambetter would be the title sponsor of the race starting in 2023.
