NASCAR Reduces Downforce At Short Tracks, Road Courses For 2020 Cup Series

Officials from NASCAR have announced a reduced-downforce package for the 2020 Cup Series season. The new rules are designed to enhance competition on road courses and the circuit’s shorter oval tracks.

Smaller spoilers, splitters, and other aerodynamic devices are among the changes, which will put more emphasis on handling and driver input.

“Our first and foremost core goal is to deliver great racing, and I think that we constantly evaluate the things that we do on the race track, however, and wherever we need to, to improve that situation for them,” NASCAR Senior Vice President, Innovation and Racing Development John Probst said to NASCAR.com. “And as part of our normal ongoing critique of ourselves and how we’re doing, we just felt like this was a good opportunity for us to improve the on-track product at the short tracks and road courses.”

Among the changes for those specific tracks:
    •    A significantly smaller rear spoiler, which shrinks from an 8-inch height to 2.75 inches.
    •    The front splitter’s overhang will now measure a quarter-inch (down from 2 inches), with approximately 2-inch wings (reduced from 10.5 inches).
    •    Alterations to the radiator pan, removing its vertical fencing in an effort to reduce front-end downforce. The dimensions of the pan remain the same.

The changes will be in effect for nine of the 24 layouts—three road courses and six ovals—that the NASCAR Cup Series will visit in 2020.

The six oval tracks that will use the new rules this season:
    •    Bristol Motor Speedway (.533 miles)
    •    Dover International Speedway (1 mile)
    •    Martinsville Speedway (.526 miles)
    •    New Hampshire Motor Speedway (1.058 miles)
    •    Phoenix Raceway (1 mile)
    •    Richmond Raceway (.75 miles)

All three road courses on the Cup Series schedule will have the new rules in place:
    •    Charlotte Motor Speedway Roval (2.28 miles)
    •    Sonoma Raceway (2.52 miles)
    •    Watkins Glen International (2.45 miles)
