Source-derived summary

The Coke Zero Sugar 400 is an annual NASCAR Cup Series stock car race at Daytona International Speedway. First held in 1959, the event consists of 160 laps, 400-mile (640 km), and is the second of two major stock car events held at Daytona on the oval, the other being the Daytona 500. From its inception in 1959, it was traditionally held on or around the United States' Independence Day until 2019. In 2020, the race was moved to late August and has been the last race of the NASCAR regular season.

Since 2002, the NASCAR O'Reilly Auto Parts Series Winn-Dixie 250 race is held on Friday night. Ryan Preece is the defending winner of the race, having won it in 2026.

History

1959–1969

Prior to the opening of the track, and prior to the inaugural Daytona 500, tentative plans were made to host a 300-mile USAC Championship (Indycar) race on Independence Day weekend of 1959. However, following two separate fatal accidents to drivers Marshall Teague (testing) and George Amick (Daytona 100), speedway officials canceled the race, citing dangerously high speeds, as well as a low turnout. Bill France Sr. announced plans to hold a 100-lap/250-mile NASCAR stock car race instead, scheduled for July 4.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as auto race held in Daytona, United States. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q1094440. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1959, 2019, 2020 and 2002.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
