The AAA 400 Drive for Autism is a premier NASCAR Cup Series race run at Dover International Speedway in Dover, Delaware. Held in the spring portion of the Cup schedule, the event covers 400 miles around Dover's one‑mile oval — hence 400 laps — and is one of two annual Cup races at the facility. The race is closely associated with autism awareness through its title sponsorship and charitable initiatives.

Race characteristics

Dover is commonly known as "The Monster Mile" because of its fast, tight configuration and steep banking that challenge drivers and equipment. The 400‑mile distance produces a demanding test of tire and engine management; the race often features pit strategy, attrition, and late‑race restarts that can dramatically change the outcome. As a points race on the Cup calendar, it attracts top teams and plays a role in the championship season.

History and development

The spring Cup race at Dover has evolved in distance and sponsorship over the decades. Originally contested at a longer distance, organizers shortened the event from 500 miles to 400 miles in 1998 to improve on‑track competition and fan experience. In 2016 AAA became the event's title sponsor and added an autism awareness component, which is reflected in the race name and community programming.

Significance and notable aspects

  • One of two top‑level NASCAR races held at Dover each year, the spring race complements a fall date on the same track.
  • Known for memorable, edge‑of‑control finishes and last‑lap passes, the event has provided frequent dramatic highlights in Cup history.
  • The race's affiliation with autism charities brings fundraising, community outreach, and educational activities to the speedway and region.

Because of its short, intense laps and high speeds, the AAA 400 often produces high attrition and close battles among veterans and rising drivers alike. Teams emphasize pit timing, tire conservation and setup balance for both long runs and restarts. For fans, the combination of competitive racing and the event's charitable mission defines the AAA 400 Drive for Autism as a notable stop on the NASCAR Cup Series schedule.
