TALLADEGA, Ala. (AP) — When rain stopped NASCAR’s playoff race at Talladega Superspeedway, a gaggle of Chevrolet drivers headed into a private room for a meeting about alliances.

That strategy session was a Sunday bonus in the battle of the manufacturers. NASCAR was able to get in 57 laps, all the way until the end of the first stage, before the rain began and teams were given a break.

The race was ultimately postponed and will resume today. In completing the entire first stage Sunday, teams got a preview of who is fast, who works well together, and if the battle of the manufacturers will dictate the outcome.
