“We did some testing with IndyCar late last year and tried this change,” Simmons added. “IndyCar did some CFD work to find why it wasn’t easy to follow other cars, and one of the studies found the air separated at the edge of the wing next to the end plate, where it stalls, and the solution they came up with was to shorten the chord at the ends of the wing by cutting out the notches, which reduces the stall, cleans up the air and makes the front wing more efficient and consistent for the drivers in traffic.”
