UPDATE: Among the other changes and updates announced at the R&D briefing:
- Xfinity Series director Wayne Auton said a 2.41-mile, 14-turn layout will be used at Indianapolis for the series’ first race on the Brickyard’s road course.
- Officials also settled on a tire combination that’s also used at Road America and Mid-Ohio Sports Car Course. No organizational test is planned on the Indy road-course layout, but teams will get an extended practice session on race weekend.
- NASCAR officials will meet with current manufacturers and prospective new ones Wednesday to discuss a timeline for a new engine in Cup Series competition. The earliest timetable for the advent of electrification is 2022. The arrival of any new engine could not come until 2023.
- The Triple Truck Challenge for the Gander RV & Outdoors Truck Series will return for 2020 but with a new schedule: Richmond Raceway (April 18), Dover International Speedway (May 1) and Charlotte Motor Speedway (May 15). Last year’s bonus program raced at Texas Motor Speedway, Iowa Speedway and World Wide Technology Raceway at Gateway last June. The entry deadline restriction that determined eligibility for last year’s debut of "The Trip" has been lifted.
- Cup Series director Jay Fabian said more cars would likely come back to the R&D Center for post-race evaluation in 2020. With a parts freeze in place, Fabian said inspectors would take a closer look at trends and components on a given week.
- There are no changes to Xfinity Series aero package for the 2020 campaign. Auton said 37 full-time teams are expected to participate this season.

ORIGINAL POST: NASCAR has changed the length of stages for 16 Cup races this season, primarily shortening the final stage in those events.
The overall length of those races did not change, except for the Pocono doubleheader events. NASCAR also announced that with the stages changing, the end of Stage 2 will go beyond the halfway point of the race. NASCAR stated that a Cup race would be official at the halfway point should it have to end early, a change from last year.
… stage lengths had yet to be set this season for the races at Watkins Glen, Sonoma and the Charlotte Roval.
Miller also said that NASCAR explored the notion of four stages for every event – only the Coca-Cola 600 has four stages – but that was dropped.
