The session was the only on-track activity for NASCAR Cup Series teams on Friday, and featured manufacturer teammates drafting together in separate packs.
Among those in the Chevrolet pack were Byron, Preece, Elliott, Bowman, Johnson, Ty Dillon, Reddick, Austin Dillon, Darrell Wallace Jr., Ross Chastain, Justin Haley, and Ricky Stenhouse Jr.
The Ford pack featured Brad Keselowski, Ryan Newman, Ryan Blaney (in his backup car), Matt DiBenedetto, Cole Custer, Joey Logano, David Ragan, John Hunter Nemechek, and Chris Buescher.
And the smallest drafting group was the manufacturer with the least teams, Toyota. Hamlin, Jones, Truex, Christopher Bell, and Kyle Busch took turns either pushing or pulling the pack.
Corey LaJoie also made in on track for practice in his backup car.
Only 32 of the 40 teams entered in the Daytona 500 participated in the session.
