History
The event began as an attempt by NASCAR to stage a Memorial Day weekend event to compete with the open-wheel Indianapolis 500. It was not until 1974, however, that both races competed head-to-head on the same day, due to Indianapolis' policy of not racing on Sundays prior to that.[5] Before 1974, the two races were held on different days of the week, and on a few occasions, some drivers drove in both. They continued even after the Coca-Cola 600 was moved to the same day, albeit to a lesser degree. The first World 600 was held on June 16 due to construction delays of the completion of Charlotte Motor Speedway. The 2009 race, postponed by rain from its original May 24 date, was the first race to occur on Memorial Day itself.
After the installation of lights in 1992, fans asked circuit management to start the race later in the day because of the notorious North Carolina heat and humidity. They wanted to follow The Winston's popularity the previous week and switch the race to a nighttime finish to create cooler temperatures for spectators. The start time was moved back several times throughout the 1990s and finally settled at 5:30 pm in 2001, to attempt to have the race finished by 10 pm ET, in time for local news on Fox affiliates. With the new starting time came new challenges. Not only do race teams have to deal with the blistering Carolina heat, but the considerable temperature drop at night affects track conditions.
The nighttime portion of the race is lit with a system that uses parabolic reflectors so that dangerous glare that would otherwise be in the drivers' eyes is minimized. The move of the race to the early evening made it possible for drivers to do Double Duty – run the Indianapolis 500, then immediately fly from Indianapolis to Charlotte, and participate in the Coca-Cola 600. Experts disagreed over whether, for health and safety reasons, anyone should be allowed to race 1100 miles in one day, but no regulation has been set by any governing body to prevent it. From 2005 to 2010, the issue became moot when the state of Indiana finally decided to implement daylight saving time. This resulted in only an approximately one-hour interval between the end of the Indianapolis 500 and the start of the Coca-Cola 600. The Indianapolis 500 start time was moved back to noon Eastern in 2011, since 2011, only 2 drivers have attempted the Double Duty, with the most recent being Kyle Larson in 2024, however, due to rain, he was unable to race in the Coca-Cola 600.
Until the Ferko lawsuit settlement took effect, the race was considered the third leg of the grand slam and was once part of the Winston Million. It is considered one of the top five annual NASCAR races.[6]
Beginning in 2017, NASCAR adopted the stage-racing format, dividing each of its top three division's races into three stages. Originally, the 600 was going to have stages 1 & 2 be 115 laps in length, with the third and final stage encompassing the remaining 170 laps. Just a few weeks before the race, the stage format for the race was changed with the addition of a fourth stage, and the race is divided into four uniform stages of 100 laps each. This makes it the only race on the schedule with four stages instead of three. If the weather interferes, NASCAR's rule that a race becomes official after the conclusion of the second stage still applies. It also makes the Coca-Cola 600 the highest scoring race in terms of points a driver can collect. Usually, if a driver sweeps all the stages and passes inspection they score 60 points (40 for winning, and 10 for the first two stages), but with 4 stages the maximum is 70 (which Kyle Busch accomplished in 2018 and Kyle Larson accomplished in 2021[7]).
As part of the race’s annual tribute to the United States military, "Amazing Grace" (performed by the Charlotte Fire Department Pipe Band) and "Taps" are played prior to the National Anthem (usually sung by a military ensemble or personnel) in memory of members of the Armed Forces who lost their life in the line of duty.
