​Daytona International Speedway just got faster.Or at least that’s the hope.On July 15, NASCAR announced updates to the Cup Series’ superspeedway package for the Coke Zero Sugar 400.The rear spoiler will be shortened from 7 inches to 4, making it the same height as intermediate tracks, in an effort to reduce drag. The horsepower will also drop from 510 to 465 to account for reduced downforce.AdvertisementAdvertisementAdvertisementNASCAR hopes the changes will provide more opportunities for drivers to pass and less reliance on fuel-saving strategies to gain positions. It expects single-car runs to be 3 mph faster while speeds for cars in a pack won’t be affected much.Buy our Dale Earnhardt book here1 / 19HAMPTON, GEORGIA – JULY 12: Chase Elliott, driver of the #9 NAPA Auto Parts/CHOA Chevrolet, and Christopher Bell, driver of the #20 Rheem Toyota, race during the NASCAR Cup Series Quaker State 400 Available at Walmart at EchoPark Speedway on July 12, 2026 in Hampton, Georgia.

It remains undetermined whether the final superspeedway race of the season — at Talladega in October — will adopt the new practices.Denny Hamlin, who served on a committee for the updates, broke down the reasoning.“What we’re essentially trying to recreate is Atlanta at Daytona and Talladega,” he said on “Inside The Race.” “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. Guys are dicing it up the entire race.AdvertisementAdvertisementAdvertisement“So this is what we’re aspiring to get to at some point. And it’s going to take chunks here and there.
