Background
Daytona International Speedway is one of six superspeedways to hold NASCAR races; the others are Michigan International Speedway, Auto Club Speedway, Indianapolis Motor Speedway, Pocono Raceway and Talladega Superspeedway. Its standard track is a four-turn, superspeedway. Daytona's turns are banked at 31 degrees and the front stretch (the location of the finish line) is banked at 18 degrees. The defending winners of the races were Jimmie Johnson and Kasey Kahne.
In the early years, qualifying for the Daytona 500 had varying formats: from one timed lap, to the average of two laps, to the better of two laps. The idea of having two individual races to establish the starting lineup of the Daytona 500 dates back to the first race in 1959. The first of the 100-mile (160 km) qualifying races consisted of Convertible division cars and the second of Grand National cars. Between 1960 and 1967, the races were and were increased to in 1969. Prior to 1971, the races yielded points to the Drivers' Championship. Large well-established teams approach the races as practice sessions for the Daytona 500 while a successful qualification into the Daytona 500 for smaller less-established teams would allow them to enter future NASCAR events during the season. An unsuccessful qualification meant the team would risk closing down until sponsorship was found. Corporate sponsors purchased naming rights to qualifying races; between 1981 and 1984, Uno cards was the title sponsor for the "Uno Twin 125’s" qualifying events. In 1985 they became known as "7-Eleven Twin 125's"; no sponsors funded the 1988, 1989 and 1990 qualifying events and the races were called "Daytona Twin Qualifiers". Gatorade became the sponsor of the dual qualifying events in 1991 and the races were increased to as it became known as the "Gatorade Duels" in 2005. The races were rebranded as the "Budweiser Duels" in 2013 and became known as the "Can-Am Duels" in 2016.
The top 35 drivers were assigned to Gatorade Duel races based upon their qualifying positions in the previous year's Daytona 500. Drivers who qualified in odd-number positions competed in the first Duel along with the winner of the 2011 Daytona 500 pole. Competitors who qualified in even-numbered places took part in the second Duel. The drivers' finishing positions in both Duels determined their starting positions in the Daytona 500. Positions 40 to 42 were filled with the quickest drivers who did not qualify in the top 35. 43rd place was occupied by an eligible past champion. In the event a past champion was not available, the 43rd position would be filled by the next-fastest driver. Two drivers outside the top 35 qualifying positions were eligible for two transfer spots in each Duel which allowed them to qualify for the Daytona 500.
