Most of the IndyCar grid drivers participated in a testing session at Iowa Speedway on Thursday, which focused on evaluating the newly resurfaced track surface and testing the hybrid power unit.
During the test, the drivers completed laps both in the afternoon and at night, mimicking the time period of the races in July. Overall, the drivers had positive opinions about the new track surface, noting that the resurfaced areas were very smooth. This smoothness resulted in minimal tire degradation and faster lap times.
A notable observation was that racing on the lower part of the curve seemed to offer an advantage, although there were differing opinions on whether this would affect overtaking during the actual race.
Graham Rahal expressed his enthusiasm for the resurfaced track, stating that the turns were incredibly smooth and lap times were faster compared to last year. He believed that the new surface could open up a second racing line, making the event exciting.
The hybrid system performed well during the test, with no reported issues with the electrified power system. However, the overall impact on performance seemed minimal at the current power levels established by the series.
To ensure a smooth transition, IndyCar is taking a cautious approach, initially limiting the power of the hybrid units. This conservative strategy aims to minimize any potential issues during the debut of the hybrid system at the next race at Mid-Ohio Sports Car Course.
Teams have an adequate number of units to complete the race weekend, and spare components are available at Honda and Chevy if needed.
The full debut of the hybrid systems will take place during the Friday afternoon practice session, followed by the Honda Indy 200 on Sunday, July 7th, at 1:45 PM. Subsequently, the paddock will return to Iowa Speedway for a double race weekend on July 13th and 14th.
