• The Folds of Honor QuikTrip 500 at Atlanta Motor Speedway moved from the second race to the fifth race of the season behind the West Coast swing to March 15, 2020, returning to its pre-2010 date of mid-March.
• The Dixie Vodka 400 at Homestead–Miami Speedway moved to March 22, 2020, no longer serving as the season finale.
• After 21 years of being held in proximity to Independence Day weekend, the Coke Zero Sugar 400 at Daytona International Speedway moved to August to become the final race of NASCAR's "regular season". The Brickyard 400, run at Indianapolis Motor Speedway, moved to the Independence Day weekend scheduling.
• The Blue-Emu Maximum Pain Relief 500 at Martinsville Speedway was switched to a Saturday night race on May 9.
• Kansas Speedway's spring race, the Digital Ally 400 moved to a Sunday afternoon race on May 31 (vacating the Mother's Day weekend scheduling now held by Martinsville), following the Coca-Cola 600.
• Pocono Raceway's two races were consolidated into a doubleheader weekend, with the Pocono Organics 325 and Pocono 350 held across two consecutive days. The starting order for the second race would be determined by reversing the order of the lead lap finishers from the first race.[154]
• Dover International Speedway's second date moves to late August, marking the first time the race has not been in NASCAR's postseason.
• The Toyota/Save Mart 350 will move one week earlier than 2018.
• The Southern 500 at Darlington Raceway will be held as the first race of the Playoffs, as the South Point 400 at Las Vegas Motor Speedway will move to the first race of the Round of 12.[155]
• The Bass Pro Shops NRA Night Race at Bristol Motor Speedway will move from mid-August to mid-September, replacing Charlotte and becoming the final race of the Round of 16.
• The Championship Round of the Playoffs will be conducted at Phoenix Raceway on November 8. This will be the first Phoenix race to close out the season. Due to this and the consolidation of the Pocono doubleheader, the 2020 season will end one week earlier than in the past. Usually, the season finale had been held on the third weekend in November, falling sometime between November 16–22.
• The Bank of America Roval 400 at Charlotte Motor Speedway will become the final race of the Round of 12, replacing Kansas.
• The Hollywood Casino 400 at Kansas Speedway will be held one week later than 2019, replacing Martinsville and becoming the first race of the Round of 8.
• The Toyota Owners 400 at Richmond will move back to Sunday afternoon, similar to 2015–2017 when it was run on a Sunday afternoon. This was done because the two Martinsville Speedway races will be night races in 2020, as both races will start in the day and end at night.
• Two off-weeks between Loudon and Michigan were scheduled to accommodate the (now-postponed) 2020 Summer Olympics (which are broadcast by NBCUniversal networks).

• The Folds of Honor QuikTrip 500 at Atlanta Motor Speedway and the Dixie Vodka 400 at Homestead–Miami Speedway were originally announced on March 12, 2020 due to the coronavirus (COVID-19) pandemic to take place without fans in attendance, but one day later on March 13, 2020, NASCAR announced that the two Cup races (including support races) would be postponed.[156]
• On March 16, 2020, NASCAR announced all race events through May 3 have been postponed due to the coronavirus (COVID-19) pandemic.[157]
• On April 17, 2020, NASCAR announced that Martinsville Speedway race weekend on May 8–9 had been postponed, although the sanctioning body affirmed its commitment to running a full 36-race schedule.[158]
• On April 30, 2020, NASCAR announced a revised schedule for the month of May, with two Cup races at Darlington Raceway and two points-paying races at Charlotte Motor Speedway, including the Coca-Cola 600 that will be run with no fans in the stands.[159]
• On May 8, 2020, NASCAR announced that Sonoma Raceway and Chicagoland Speedway would not host Cup races in 2020, and that Richmond Raceway's postponed spring date would not be rescheduled.[160]
• On May 14, 2020, NASCAR announced another revised schedule, this time to show the races planned for the end of May through June 21. These tracks include Bristol Motor Speedway, Atlanta Motor Speedway, Martinsville Speedway, Homestead-Miami Speedway, and Talladega Superspeedway. NASCAR also announced a continuation of its empty stands policy for those races.[161] Homestead would eventually end up inviting 1,000 Military Members, their families, and First Responders to watch the race live in person and Talladega would eventually allow 5,000 fans and limited camping for the GEICO 500 race on Monday.
• With the exception of the Coca-Cola 600, all races starting with NASCAR's return at Darlington through the Homestead race at minimum will feature no practice or qualifying. Teams will unload, have cars inspected, and race. The Coca-Cola 600 will feature qualifying only a few hours before the race but no practice.[162]
• On June 15, NASCAR announced due to the state of North Carolina not able to allow sporting events with fans, that they would move the NASCAR All-Star Race to Bristol Motor Speedway with the rescheduled date being intact and the format to be announced at a later date with up to 30,000 fans being allowed in the stands.[163]

Kyle Larson got into the wall after contact with Denny Hamlin, but was able to keep going. Ryan Blaney won the second stage. Hamlin made contact with the wall.

Joey Logano held off Harvick for his second win of the season.[171] Kyle Larson finished 4th but unbeknownst to all at the time, this would be his final race with Chip Ganassi Racing.

Season paused for two months due to the COVID-19 pandemic

The fifth race of the season was supposed to be the 2020 Folds of Honor QuikTrip 500, the first race at Atlanta since its rescheduling from being the second race of the season (in late February or early March, which it was for 5 years) to mid-March immediately after the west coast swing (the races at Las Vegas, Fontana, and Phoenix) as part of the 2020 schedule changes.

Prior to the Atlanta race, NASCAR announced that no fans would be permitted to attend it due to the COVID-19 pandemic.[172] However, it was announced the following day that the race would instead be outright postponed to sometime later in the season. The same restrictions applied to the following race, the 2020 Dixie Vodka 400, at Homestead-Miami Speedway.[173] It was supposed to be the first Homestead race since its rescheduling from being the season-finale in November (which it was for 18 years) to March as the sixth race of the season as part of the 2020 schedule changes.

Round 5: The Real Heroes 400

This was NASCAR's first race back since the pandemic hit. It was run on May 17 as a one day show, with no fans in attendance. This additional race at Darlington replaced the race at Chicago in June on the schedule. NASCAR announced that there would be no practice or qualifying held so that teams would not need to bring additional crew members to the track and would not need to bring backup cars.[159][160]

Brad Keselowski was awarded the pole position by a random draw, which was done on the Thursday before the race and televised on NASCAR Race Hub.[174] Ricky Stenhouse Jr. wrecked on the first lap of the race. Jimmie Johnson was leading at the end of the first stage but wrecked after contact with Chris Buescher on the last lap of the stage, with William Byron winning the stage. Keselowski won the second stage of the race. Kevin Harvick led the most laps and won the race, his second win at Darlington and 50th career win.[175]

Round 6: Toyota 500

The second race to air during prime time this season[176] also saw no fans in the stands much like the previous race. Positions 1 through 20 from Sunday’s race were inverted, which meant Ryan Preece started on pole by virtue of his 20th place finish on Sunday.[159][160] Positions 21 through 40 made up the remaining half of the grid. The Tommy Baldwin racing entry driven by Josh Bilicki did not enter this race which meant only 39 cars started. J. J. Yeley and Gray Gaulding started in the rear due to them not participating in Sunday’s race. The race saw Preece, the pole sitter, blow a motor during the first stage and fail to finish. Clint Bowyer led the most laps and won the first and second stages, but got into the wall and spun late in the race. Denny Hamlin was leading when the final caution came out with 28 laps to go when Chase Elliott made contact with Kyle Busch and spun into the inside wall. During the caution period rain started to fall which caused NASCAR to red flag the race. With 20 laps remaining NASCAR declared Hamlin the winner. This was Hamlin’s second victory of the season.[177]

Round 7: Coca-Cola 600

This race occurred on its originally scheduled date of May 24 but was the first race since the COVID-19 pandemic to feature qualifying as part of a one day show. Kurt Busch started on pole for the race. At the beginning of the race, Denny Hamlin lost ballast from his car and was forced to pit, resulting in him starting the race multiple laps down. The race was red-flagged due to rain during the first stage. Alex Bowman won the first stage of the race under caution after Clint Bowyer got into the wall. Bowman also won the second stage of the race. Joey Logano won the third stage of the race. Chase Elliott was leading late in the race when William Byron spun with two laps to go, setting up an overtime finish. Elliott and several cars came to pit road while other drivers stayed out. Brad Keselowski took the lead and won the race in overtime. Jimmie Johnson crossed the finish line 2nd but failed post-race inspection, resulting in him being disqualified and finishing the race in last place meaning he will start in last place in the next race.[178]

Round 8: Alsco Uniforms 500

The race was postponed from Wednesday to Thursday due to rain. The top 20 from the Coca-Cola 600 was inverted, which meant that William Byron started on pole. Joey Gase and Garrett Smithley got into the wall on the first lap and collected Tyler Reddick and Ty Dillon. Byron had to pit after making contact with Corey LaJoie on pit road. Kyle Busch cut a tire after making contact with Aric Almirola. Brad Keselowski cut a tire and got into the wall along with Matt Kenseth. The race was red flagged due to rain. When the race resumed, Joey Logano won the first stage. Alex Bowman won the second stage and led the start of the final stage until he got into the wall and had to pit. Kevin Harvick took the lead, but Chase Elliott passed Harvick for the lead and held off Denny Hamlin for his seventh career win.[179]

Round 9: Food City presents the Supermarket Heroes 500

A random draw determined the starting lineup with Brad Keselowski starting on pole. After two competition cautions, Chase Elliott won the first stage. Ryan Blaney spun while second and collected Ty Dillon. Ricky Stenhouse Jr. spun and collected several cars including Alex Bowman, Cole Custer, Tyler Reddick, Ryan Preece, and Matt DiBenedetto, which brought out the red flag. Elliott won the second stage as Kevin Harvick made contact with Erik Jones and got into the wall. Bubba Wallace made little contact with Aric Almirola and collected Martin Truex Jr. Denny Hamlin spun after battling Joey Logano for the lead. Elliott got loose and put himself and Logano into the wall, which allowed Keselowski to take the lead and hold off Clint Bowyer for his second win of the season.[180]

Round 10: Folds of Honor QuikTrip 500

Chase Elliott won pole from random draw. Kurt Busch had to serve a drive-thru penalty in the first laps due to failing pre-race inspection multiple times. Martin Truex, Jr. won both stages as Michael McDowell and John Hunter Nemechek both had spin outs that brought the only incidents of the day. Kevin Harvick will go on to lead the most laps and grab his second win of the season.[181]

Round 11: Blue-Emu Maximum Pain Relief 500

The first night race to take place at Martinsville since the implementation of the lights in 2017, and the first race to ban all confederate flags from sports events in response of the death of George Floyd. Ryan Blaney won pole from random draw as a quick caution on lap 5 came out for debris from Austin Dilion's car. He would eventually retire from the race on the final stage due to overheating inside the car. Many noticeable drivers, including Kyle Busch, Denny Hamlin, Erik Jones, Brad Keselowski, Blaney, and Matt Kenseth would struggle in the first stage and would already be a lap or two down until the competition caution came out at lap 60. Another caution would come out with 10 to go in stage 1 from Timmy Hill stalling on pit road. Most drivers who were a lap down opted to take the wave around, but Corey Lajoie opted not to pit while on the lead lap, thus trapping all the wave arounds stuck a lap down. Joey Logano will go on to win stage 1 while Jimmie Johnson would win stage 2. Martin Truex, Jr. was busted from going over the commitment box while pitting and had to restart at the tail-end. Two more cautions would come out for incidents involving David Starr and Quin Houff. Truex would assume the lead in the latter portion of the race and would win for the second consecutive time at Martinsville, beating second place Ryan Blaney by 4.232 seconds.[182]

Round 12: Dixie Vodka 400

Denny Hamlin won pole as the start of the race was delayed due to lightning in the area, and again on lap 5. Ryan Newman would spin out in the first stage as Hamlin would go on to win both stages. Chase Elliott led late in the race, but was blocked by lapped car Joey Logano due to their incident that happened at Bristol several weeks prior, allowing Hamlin to regain the lead and score his third win of the season.

Round 13: GEICO 500

The race was pushed from Sunday to Monday afternoon due to rain and lightning that washed out the track. Martin Truex, Jr. started on pole from random draw. Denny Hamlin would hit the wall late in stage 1 and would have to repair under green. 5 laps before the end of stage 1, a shower damped the track forcing the red flag for almost an hour. Tyler Reddick would win stage 1 under yellow following race resumption. John Hunter Nemechek would spin out in turn four to bring the only incident in stage 2 as Ricky Stenhouse, Jr. would win stage 2. Stage 3 would see two minor crashes involving Chase Elliott and Austin Dillon with 50 to go, and Brennan Poole and Joey Gase would crash with 46 to go. This caution would ultimately turn into a fuel mileage race as many would either barely make it while others would be a few laps short. The race would run green until 3 laps to go when Jimmie Johnson got turned by Kevin Harvick at the start/finish line forcing the race into overtime. Drivers up front like Ryan Blaney, Stenhouse, and Harvick would opt not to pit in order to keep track position and save fuel. On the overtime restart, Harvick would get a push from Chris Buescher to the lead. On the final lap, several drivers would crash in turn 3 involving Clint Bowyer, Matt Dibenedetto, and Truex, allowing Blaney to pass Harvick and score his 4th career win in the Cup Series, beating out Stenhouse by 0.007 seconds as Erik Jones, Aric Almirola, and Nemechek crash coming to the finish.
