The Coca-Cola 600 (formerly the World 600), and also known as the "Coke 600" and "600" is a 600 miles (965.6 km) in length stock car race held annually at Lowe's Motor Speedway (formerly Charlotte Motor Speedway) in Concord, North Carolina on Memorial Day weekend. It is the longest NASCAR Sprint Cup Series race and, in fact, is the longest regularly-scheduled automobile race conducted on an oval track anywhere in the world.
The event was started as an attempt by NASCAR to stage a Memorial Day weekend event that would rival the open-wheel Indianapolis 500 in fan interest and it has succeeded, gaining larger TV ratings than the Indianapolis race from 2002-2004. It was not until 1974, however, that both races competed head-to-head on the same day. Prior to 1974, the two races were held on different days of the week, and on a few occasions, some drivers drove in both; this continued even after the 600 was moved to the same day, albeit to a smaller degree.
With the installation of lights in 1992, fans complained to circuit management to have the race start 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 5:30PM in 2001, to attempt to have the race finished by 10 p.m. 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 change at night make track conditions completely different.
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 participate in both the 600 and the Indianapolis 500 by flying from Indianapolis to Charlotte as soon as the Indianapolis race was over. Experts disagree over whether, for health and safety reasons, anyone should be allowed to race 1100 miles in one day, but no regulation has been passed yet by any governing body to prevent it. Beginning with the 2005 races, the issue became moot as the state of Indiana finally decided to go to daylight saving time. This resulted in only about a one hour span between the end of the Indianapolis race and the start of the Charlotte race.
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.
50th running of the Coca-Cola 600 at Lowe's Motor Speedway has been postponed due to inclement weather.
