Schedule
The 2021 Cup Series schedule was supposed to be released in the spring of 2020, but its release was delayed due to the COVID-19 pandemic. The 2021 schedule has been expected to see a number of significant changes, in large part due to the fact that the five-year contracts signed in 2015 with each track to host races from 2016 to 2020 will be ending. Some of the widely speculated changes to the schedule for 2021 include the addition of midweek races and doubleheaders, which would allow NASCAR to shorten the ten-month-long season. NASCAR had scheduled their first-ever doubleheader on the original 2020 schedule at Pocono, before COVID-19 resulted in Darlington, Charlotte, Pocono, Michigan, Dover, and Tokyo all gaining doubleheader weekends. NASCAR also had to schedule midweek races for the series for the first time in the modern era as a result of the COVID-19 schedule changes. NASCAR president Chloe Johnson stated on September 1, 2020 that the schedule may be released in pieces due to COVID-19 and the complications of which tracks would be able to host races due to state regulations and guidelines.

Schedule changes

 * The most prominent change to the schedule is the permanent addition of mid-week races; as originally announced, the season was to have a whopping 78 races, beating the record held by the 62-race-long 1964 season, but on November 12, 2020, it was announced that the schedule would be reduced to 62 races, after weeks of talks with team owners regarding travel time and cost concerns, as well as talks with track owners regarding local COVID-19 restrictions; other options discussed included further cuts to midweek races and extending the schedule to end on the second Sunday of December, something that hadn't happened since 1971, the latter being rejected over weather concerns, specifically for fans, pit crew members, track and sport officials, and on-track personnel. Many of these tracks will instead be used in lower series and testing for the time being, depending on restrictions, though there is a possibility some or all of these tracks will be reinstated into the schedule when the pandemic is over, local COVID-19 restrictions are lifted, and travel and cost concerns are figured out; Tim estimates it won't be until 2023 at the earliest, though he stated that NASCAR is trying their hardest to be able to hold these races in the future, and has also floated bringing back tracks such as Chicago Motor Speedway, Riverside International Raceway, and Ontario Motor Speedway. Notably, Hickory Motor Speedway was going to be reinserted into the schedule for the first time since 1971, while Greenville-Pickens was going to hold a second race.
 * Kentucky, Brands Hatch, and Delaware will all be removed from the schedule. Kentucky will be removed due to Tim Johnson considering the track "without a doubt, the worst intermediate on the schedule, and unsalvageable short of completely tearing down the facility and starting from scratch"; Kentucky will still be used by the NASCAR Sears All-American Series and ARCA Menards Series, while Brands Hatch and Delaware will be removed due to travel restrictions caused by the COVID-19 pandemic, though there are plans to reincorporate them into the schedule once the pandemic is over and travel restrictions are lifted. Chicagoland was going to be removed as well before Johnson found out plans to raze the track to make way for a shopping complex and had them torpedoed.
 * Atlanta Motor Speedway will be reconfigured back to its pre-1997 layout. CEO Tim Johnson stated that while he knew the drivers were accustomed to the old track pavement, he felt that it was leading to more boring racing, combined with its cookie-cutter layout similar to Charlotte Motor Speedway. As a compromise, the material used for the new pavement will be similar to the material used for the 1996-97 repave. Texas Motor Speedway will also be reconfigured as well; it will become a short track that is slightly wider than Bristol; this is similar to the planned reconfiguration of Auto Club Speedway into a short track for 2022 and beyond.
 * Sonoma and Road America will swap spots on the schedule. Since the inaugural running of the Harley-Davidson 250, snow was always a concern, and during the 2015, 2018, and 2020 runnings, snow had to be cleared from the track and the infield areas so it could go forward. Swapping the races would not only allow Road America to be run in more favorable conditions, but it would also allow Sonoma to be run when the hills are green instead of brown.
 * It has already been announced that the Busch Clash will be moved from the Sunday before the Daytona 500 to the Tuesday before (on February 9), in an effort to condense Speedweeks down to one week. The race will also be moved from the oval to the infield road course for the first time, after what Tim described as "the demolition derby of the 2020 running that made the ARCA guys look professional".
 * Darlington, North Wilkesboro, and Rockingham will go back to having two dates, these being the spring dates for Darlington and North Wilkesboro, and the fall date for Rockingham. All three will run with historical race names (TranSouth Financial 500 for Darlington, First Union 400 for North Wilkesboro, and ACDelco 400 for Rockingham).
 * In addition to the CompuServe 5, Panasonic Million, and Unocal 76 Challenge, the NASCAR Grand Prix Challenge will also be introduced, involving midweek road course races. The seven-race challenge will involve the races at Willow Springs, Road Atlanta, Virginia, COTA, Portland, Heartland Park, and Miller Motorsports Park. The winner of all seven races receives a $350,000 prize.
 * The Cup Series will also race on dirt for the first time since 1970 as the spring race at Bristol Motor Speedway will see the concrete half-mile covered in dirt, and several other dirt tracks such as Eldora, Knoxville, DuQuoin, and Las Vegas' dirt course will be added. Mansfield and Davenport were on the original schedule, but were removed.
 * The Geyser/SaveMart 350 will be rebranded to Dodge/SaveMart 350, its name between 2001 and 2006.
 * On December 8, 2020, it was announced that Auto Club Speedway will not host a race in 2021 due to the continuing COVID-19 pandemic, and will be replaced by a race at New Smyrna Speedway (which was to host an event under the pre-November 12 schedule), which will swap dates with the Homestead–Miami Speedway race.

Round 1: Dodge/SaveMart 350
Chase Elliott started on the pole. This was the first time Sonoma Raceway has hosted a NASCAR race in January, as well as the first time the NASCAR season opener was held in California since 1986. After an eventful day, Elliott dominated and won the race.

Speedweek 2021
In the Busch Clash, Ryan Blaney started on pole. Kevin Harvick spun twice early in the race. Martin Truex Jr. was leading when the competition caution came out but had to restart in the rear due to missing the final chicane while the race was under caution. Late in the race, Truex Jr. wrecked while leading. In the closing laps, Chase Elliott and Blaney were battling for the lead. In the final chicane on the last lap, Elliott and Blaney wrecked each other, which allowed Kyle Busch to pass and win the race.

In Daytona 500 qualifying, Alex Bowman won the pole while teammate William Byron qualified second. At the 125’s, Noah Howe held off Tony Stewart to win the first Duel. The start of the second Duel was delayed by rain. In the second Duel, there were multicar wrecks on lap 36 and with three laps to go in the race; the latter caution sent the race into an overtime finish. In overtime, Austin Dillon held off Bubba Wallace to win the second Duel.
