2019 Coke Zero Sugar 400

Daytona International Speedway, the site of the race.

The race was held at Daytona International Speedway, a race track located in Daytona Beach, Florida, United States. Since opening in 1959, the track is the home of the Daytona 500, the most prestigious race in NASCAR. In addition to NASCAR, the track also hosts races of ARCA, AMA Superbike, USCC, SCCA, and Motocross. It features multiple layouts including the primary 2.5 miles (4.0 km) high speed tri-oval, a 3.56 miles (5.73 km) sports car course, a 2.95 miles (4.75 km) motorcycle course, and a .25 miles (0.40 km) karting and motorcycle flat-track. The track's 180-acre (73 ha) infield includes the 29-acre (12 ha) Lake Lloyd, which has hosted powerboat racing. The speedway is owned and operated by International Speedway Corporation.

The track was built in 1959 by NASCAR founder William "Bill" France, Sr. to host racing held at the former Daytona Beach Road Course. His banked design permitted higher speeds and gave fans a better view of the cars. Lights were installed around the track in 1998 and today, it is the third-largest single lit outdoor sports facility. The speedway has been renovated three times, with the infield renovated in 2004 and the track repaved twice — in 1978 and in 2010.

On January 22, 2013, the track unveiled artist depictions of a renovated speedway. On July 5 of that year, ground was broken for a project that would remove the backstretch seating and completely redevelop the frontstretch seating. The renovation to the speedway is being worked on by Rossetti Architects. The project, named "Daytona Rising", was completed in January 2016, and it costed US $400 million, placing emphasis on improving fan experience with five expanded and redesigned fan entrances (called "injectors") as well as wider and more comfortable seating with more restrooms and concession stands. After the renovations, the track's grandstands include 101,000 permanent seats with the ability to increase permanent seating to 125,000.[10][11] The project was completed before the start of Speedweeks 2016.

Stage One Laps: 50

Stage Two Laps: 50

Stage Three Laps: 60 (only 27 were completed before red flag)

The Big One occurred on lap 119 when Clint Bowyer and Austin Dillon battled for the lead in intense drafting packs, leading to a 17-car crash. Kurt Busch was the leader when most leaders pitted, but when at the end of Lap 127, officials gave the signal the race would restart on the ensuing lap, Busch pitted. Justin Haley took the lead, and when lightning was detected while the cars were on the backstretch working Lap 128, the safety truck turned on its lights after lightning was detected and immediately sent the cars to pit lane before the start-finish line. After two attempts to restart the race were aborted because of lightning, further rain ended all activity. Haley was declared the winner. NASCAR then spent considerable time to score all penalties assessed for pitting before pit lane was opened before an official result was declared. Also, NASCAR does not use a countback rule as in other series where they revert to two laps prior to the lap where the red flag (which would have meant the race results would have been based on Lap 126, where Kurt Busch was the leader) was called.

NBC Sports covered the race on the television side. Rick Allen, 2000 Coke Zero 400 winner Jeff Burton and two-time Coke Zero 400 winner Dale Earnhardt Jr. called in the booth for the race. Steve Letarte called from the NBC Peacock Pit Box on pit road. Dave Burns, Marty Snider and Kelli Stavast reported from pit lane during the race. During the lengthy red flag for lightning, television coverage eventually switched over to NBCSN, where the official announcement of the end of the race was made.

MRN had the radio call for the race which was also simulcast on Sirius XM NASCAR Radio.
