NASCAR competition officials postponed a two-day test of a potential new Cup Series rules configuration for short tracks and road courses for 2024 because of the threat of rain at New Hampshire Motor Speedway.

Six Cup Series teams were scheduled to participate in the test Monday and Tuesday, on the heels of the Crayon 301 that was moved to Monday (Noon ET, USA, NBC Sports App, PRN, SiriusXM) at the 1.058-mile track due to inclement weather. According to NASCAR communications representatives, the two-day test has been moved to Monday, July 31 and Tuesday, Aug. 1 after the weekend’s events at Richmond Raceway.
Teams were scheduled to try out aerodynamic changes to the front splitter and underbody at the New Hampshire test, also working with a pair of softer-compound tires from Goodyear. Competition officials have recently conducted wind-tunnel tests and Computational Fluid Dynamics (CFD) computer modeling with the new splitter in an effort to mitigate the turbulence or “dirty air” that affects cars in traffic.
Goodyear officials tested April 25-26 at New Hampshire, with three drivers — Christopher Bell, Chase Elliott and Brad Keselowski — participating to determine the tire compound for Sunday’s Cup Series race.
