NASCAR is fighting the aerodynamic advantages with new aerodynamic disadvantages
Ahead of the 2022 season, NASCAR launched a spec chassis, making cars identical from team to team. The level playing field has bunched up the field but there’s still bugs to work out.
On Monday and Tuesday, NASCAR is testing a new short track and road course package at Richmond Raceway. Several new aerodynamic parts are being tested.
A key part of this test is a new front splitter. The sanction has brought a new splitter that packs air under it, when leading. But, if trailing a car, that air is no longer packed, thus becoming an advantage.
Currently, when drivers get behind another car, they lose downforce, dramatically. That’s made passing difficult on all tracks but it’s far more clear on single lane short tracks and road courses.
