NASCAR has announced a new rule package for its upcoming season-ending race at the International Speedway in Daytona, scheduled for August 29. This race is particularly relevant as it will determine the 16 drivers who will compete in the Chase for the Championship in 2026.
The updates include the use of a 4-inch spoiler and width splits similar to those used at intermediate tracks. Additionally, the engine taper spacer has been reduced to 27/32 for the Cup race, which will result in Next Gen cars having only 465 hp, a decrease from the previous 510-520 hp.
New support structures for the spoiler will also be implemented, as well as a deflection device designed for the new 4-inch spoiler. Series officials anticipate that single vehicle speeds during qualifying will be 2 to 3 mph faster with this updated package, while group speed will be similar to the previous version.
One of the main points of criticism regarding the previous rule package was how stagnation was observed in the final laps of races, with vehicles lined up in pairs without the option for significant maneuvers. Forming a third lane was difficult, which resulted in races that did not provide overtaking opportunities. The updates aim to facilitate these maneuvers.
This modification has been in the works for some time and is not guaranteed for races following Daytona. After this race, there will only be one more chance to compete on a superspeedway, which will take place at Talladega during the Chase on October 25.
Despite the changes, new safety features, such as the A-post flap, will remain unaltered. Drivers will not have the opportunity to practice before the race, so they will experience this rule package in the draft once the green flag is given.
