Less power, bigger passing chances: NASCAR's Daytona upgrade targets superspeedway drama

Motorsport.com argues NASCAR’s Daytona rules package—reducing superspeedway horsepower from 510 to 465 hp, cutting the spoiler, tweaking underbody aero, and changing drop gear ratios—will recreate earlier aero conditions and keep cars in the power band longer, promoting more passing and exciting racing rather than fuel-saving strategies, and narrowing the gap between pack and single-car runs to about 10–11 mph.
