Preseason Thunder, the traditional preseason testing event for NASCAR teams, will not return to Daytona International Speedway in 2027, according to a report published November 6, 2026.
The announcement marks a change in the preparation schedule for the 2027 NASCAR season. Preseason Thunder has historically provided teams with valuable track time at the 2.5-mile superspeedway ahead of the season-opening Daytona 500.
No immediate reason was given for the decision, and NASCAR has not yet announced alternative preseason testing arrangements for 2027.
