NASCAR makes major rule changes ahead of Daytona summer race

NASCAR on Wednesday announced rule changes to the Cup Series superspeedway package ahead of the Aug. 29 Coke Zero Sugar 400 at Daytona International Speedway.
NASCAR Cup Series cars will have their rear spoilers shortened from seven to four inches and a horsepower reduction from 510 to 465. Those changes are an effort to decrease drag, which has plagued Cup Series superspeedway racing since the advent of the Next-Gen car in 2022 and made it very difficult to pass at Daytona and Talladega, creating stagnant two-wide racing.
The changes are an effort to make the racing product at Daytona more similar to Atlanta, according to Cup Series driver Denny Hamlin.
“It happens organically at Atlanta, the space between the cars, because the cars themselves are grip-limited, and the fuel-mileage (racing) really doesn’t happen because you have to be on offense constantly. If you watch the pack, there is no saving,” Hamlin said, per NASCAR.com. “Guys are dicing it up the entire race. So this is what we’re aspiring to get to at some point.”
Can rule changes make speedway racing better?
Less drag should give drivers more ability to pull out of line and make moves without the fear of losing the draft. The changes will also make runs quicker and force drivers to be more decisive, just as they have to be at Atlanta.
NASCAR previously tried adjusting stage lengths at Talladega on April 26 in an effort to reduce fuel-mileage racing and create more opportunities for drivers to race hard. But in the closing laps, with every driver standing on the gas, the result was more of the same two-wide gridlock that didn’t allow drivers to pull out of line.
The rule changes implemented for Daytona could be a fix to a problem NASCAR has had for five seasons, or at least the beginning stages of a solution.
The Coke Zero Sugar 400 serves as NASCAR’s regular-season finale and is the second-to-last drafting race of the 2026 season. No rule changes have been announced for the Oct. 25 Chase race at Talladega, though they could come at a later date.
