NASCAR is bringing more horsepower to North Wilkesboro Speedway’s five-eighths-mile oval in its marquee Cup Series in 2026, the stock car sanctioning body announced Wednesday, Oct. 8.

NASCAR President Steve O’Donnell broke the news on the popular Dale Jr Download on Dirty Mo Media that the horsepower level for NASCAR Cup Series cars at ovals and short tracks that are less than 1.5-miles and road courses will increase to 750 hp starting in the 2026 season.

Including the July 17-19 Window World 400 at North Wilkesboro, the rule change will affect 17 of the current Cup Series tracks. Speedway Motorsports sister tracks Circuit of the Americas, Dover Motor Speedway, Nashville Superspeedway, Sonoma Raceway, Bristol Motor Speedway, New Hampshire Motor Speedway and the ROVAL at Charlotte Motor Speedway also will see the power boost.
