Cup Series aero package, rule changes debut at Atlanta
Many will say NASCAR’s regular season doesn’t start until this weekend.
In the Cup Series, this also applies to the cars teams are taking to the track. With the Folds of Honor Quik Trip 500 at Atlanta Motor Speedway, teams are debuting the lower-downforce aero package. This is the second season in a row NASCAR has reduced downforce on Cup cars.
Teams use a different package when they visit the two superspeedways, Daytona International Speedway and Talladega Superspeedway.
The new package has lower downforce, shorter spoilers and more adjustments. On top of the body changes, teams must start races with the tires they qualified on.
The below graphic shows off the adjustments made to Cup cars compared to the 2016 car.
