ENASCAR iRacing Pro Invitational Series

The eNASCAR iRacing Pro Invitational Series is a series of iRacing events that were organized for NASCAR drivers to compete in after its 2020 seasons were put on hold due to the coronavirus pandemic. Drivers from all of NASCAR's series competed in races each weekend on virtual versions of the racetracks the NASCAR Cup Series would have raced at that weekend had the real races not been postponed. The series began at March 21 with a race at the virtual Homestead-Miami Speedway.

Originally supposed to be a one-time event, it quickly became a weekly series, and later included the Saturday Night Thunder series of races for drivers in all NASCAR series.

Main event
Two heat races determined the starting lineup for the main event. William Byron won heat race #1, while John Hunter Nemechek won heat race #2 in a photo finish over Ryan Preece, so they started 1-2 in the race, which they coincidentally also finished 1-2 in. This was Byron's first win in the Pro Invitational Series after having strong runs in the previous two races.

Saturday Night Thunder
Similar to the Bristol race, this was the undercard event of the weekend, with drivers from all NASCAR series racing in the event. After the three heat races were held, which in order were won by Landon Cassill (No. 89), Ty Majeski (No. 45), and Josh Berry (No. 88), and Justin Allgaier (No. 7) won the last-chance qualifier. In the race itself, Berry won again. This was his first iRacing Pro Invitational Series start.

Main event
Ryan Preece won the pole and led the race for 59 laps. William Byron dominated again, leading the most laps, and holding off Timmy Hill and Parker Kligerman on the last lap to win his second Pro Invitational race in a row.

Rule changes
After cars were allowed two resets if they became damaged during the race at Homestead, it was decreased to only one reset allowed for the Texas race.

Not all Cup Series drivers were locked into the main event at Texas, as Joey Gase, Brennan Poole, and J. J. Yeley were placed in the qualifying race and had to attempt to race their way in.

The Saturday Night Thunder race from Bristol used gen-4 (old style) ARCA cars. This changed for the next one of those races at Richmond, where Xfinity Series cars were used.

Media
It was announced that Fox NASCAR, which normally carries this part of the NASCAR's racing season, would broadcast all iRacing Pro Invitational Series events, which fall in a portion of the timeslots where the actual races would have been at. Fox's booth announcers Mike Joy and Jeff Gordon broadcast from Fox NASCAR's studio in Charlotte with other FOX NASCAR personalities serving in various roles on the broadcasts.

Lower-division races were not televised on FOX.

Television viewership
903,000 viewers watched the first race at Homestead, while 1,339,000 watched the second race at Texas. These races became the most-watched eSports broadcasts ever.
