Background

The track, Daytona International Speedway, is one of six superspeedways to hold NASCAR races, the others being Michigan International Speedway, Auto Club Speedway, Indianapolis Motor Speedway, Pocono Raceway and Talladega Superspeedway. The standard track at Daytona International Speedway is a four–turn superspeedway that is 2.5-mile (4.0 km) The track's turns are banked at 31 degrees, while the front stretch, the location of the finish line, is banked at 18 degrees.

Format and eligibility

The race is 75 laps in length, and is divided into two segments; the first is 25 laps and the second is 50 laps. The race is open to those drivers who won a pole in the 2016 season or had won "The Clash" previously.

The 2017 Clash at Daytona will not be a predetermined number of cars; rather, the field is limited to drivers who meet more exclusive criteria. Only drivers who were 2016 Pole Award winners, former Clash race winners, former Daytona 500 pole winners who competed full–time in 2016 and drivers who qualified for the 2016 Chase are eligible. Daniel Suarez was also allowed to race, as Joe Gibbs Racing already had a car prepared for Carl Edwards who surprisingly retired less than a month before the race.

Brad Keselowski was the fastest in the first practice session with a time of 46.972 and a speed of 191.604 mph (308.357 km/h).^[8]

Final practice

Denny Hamlin was the fastest in the final practice session with a time of 45.795 and a speed of 196.528 mph (316.281 km/h).^[9]

Segment 1

Brad Keselowski led the field to the green flag at 11:35 a.m. under mostly sunny skies, after it was postponed from the night before.^[10] The field wasted little time packing together to form multiple lines of three-wide racing. Chris Buescher found himself out to dry as he lost the draft early on. Denny Hamlin drove to the outside of Keselowski in Turn 1 to challenge for the lead on the eighth lap. Keselowski powered back ahead, but Hamlin worked his way to the lead on lap 10. Martin Truex Jr. brushed the wall exiting Turn 4 on lap 11. The first caution of the race flew on lap 17 for a single-car wreck on the frontstretch. Exiting Turn 4, Jimmie Johnson's car broke loose, turned down and hooked the right-rear of Kurt Busch's car into the outside wall and the tri-oval grass.^[11] Busch said he was keeping to his "own business in the low groove and we got tagged in the right-rear. It's kind of a shame — all of the hard work and the effort everybody puts into the off-season — Doug Yates and his engines and everybody from Ford and everybody at Stewart-Haas, all of the effort put towards building a car and we didn't even make it to the first pit stop, so it's kind of a bummer.”^[12] He was credited with finishing last.^[13] Kyle Busch exited pit road with the race lead. Alex Bowman (speeding) and Keselowski (too many pit boxes) restarted from the tail-end of the field.

The race restarted on lap 23. Coming to the end of the segment, a few cars – including race leader (Kyle) Busch – short-pitted the end of the segment. This handed the lead to Joey Logano as the second caution flew on lap 26 for the end of the first segment. When Logano pitted under the caution, the lead cycled to Hamlin. Busch restarted the race from the tail-end of the field for speeding.

Segment 2

The race restarted on lap 30. Contrary to the two runs in the first segment, this run featured a three-car breakaway in the lead (Hamlin, Daniel Suárez and Matt Kenseth) that became a seven-car breakaway (joined by Logano, Jamie McMurray, Truex and Austin Dillon). The third caution flew on lap 50 for a single-car wreck on the frontstretch. Exiting Turn 4, Johnson broke loose a second time, slid down the track and slammed the inside wall head-on.^[14] He described both incidents as "bizarre because it drove really good everywhere else, then off of (Turn) 4 the first time I had a handling problem was when it broke free and I got into the No. 41 (Kurt Busch) and then after that, it was really loose. After that caution and the last long stretch before I crashed again, just off of Turn 4, the Sun certainly sits on that edge of the track a little bit harder than anywhere else."^[15]

The race restarted with 21 laps to go. The first five cars – consisting of Hamlin, Suárez, Kenseth, Busch and Dillon – broke away from the field. Heading down the backstretch with 17 to go, Truex was drafting with Kevin Harvick until Truex cut down across Kyle Larson, got turned and collected the wall in Turn 3, bringing out the fourth caution.

The race restarted with 11 to go. The Gibbs Toyotas controlled the lead, a viable outside line wasn't forming and the field was virtually single-file with five to go. With five to go, however, Keselowski, Logano and Harvick pulled out of line and made their way to the front. Busch split Harvick from the Penske teammates, but found himself split from his teammates as well. Using side-drafting, Keselowski and Logano split Kenseth and Suárez from Hamlin in the closing laps.^[16] With one lap to go, Hamlin was a sitting duck and the Penske teammates made their final push. Rounding Turn 1, Keselowski dove to the bottom line to pass Hamlin.^[17] Hamlin made a poorly-timed move down to block, caught himself on Keselowski's nose and got turned sideways.^[18] Logano drove to the high-side of the spin in Turn 2 and drove on to score the victory.^[19]
