The test served as a hybrid systems test and an evaluation of the newly repaved track surface, with drivers providing positive feedback on the smooth sections and low tire degradation. Running in the lower groove showed an advantage but raised concerns about passing during the event. Feedback from drivers like Graham Rahal was enthusiastic about the faster and smoother track that could potentially improve racing dynamics. The hybrid system functioned well with no reported issues during the test, although its effects on performance seem minimal at current power levels. The system will have its full debut at the upcoming Mid-Ohio Sports Car Course race weekend, with teams equipped with spare components for any potential issues. The debut of the hybrid system will kick off with a Friday afternoon practice session followed by the main race on Sunday, July 7, before moving to Iowa Speedway for a double-header race on July 13-14.
