IndyCar’s hybrid unit passed its first in-weekend test with a relatively successful debut at Mid-Ohio, but now a completely different challenge awaits on the Iowa oval. Jack Benyon takes a look at all the factors in play
After a successful debut at Mid-Ohio, IndyCar’s new hybrid unit faces rapid testing at the Iowa oval, where a recently repaved surface is expected to pose challenges. This race weekend could be the most unpredictable of the season, offering a welcome change from past dominant performances. Pato O’Ward, fresh off a victory at Mid-Ohio, stands out as the lone non-Penske winner in recent Iowa races. The resurfacing of Iowa Speedway brings high speeds and physical challenges for drivers, with the effects of reduced downforce still unknown. The lack of a higher-line grip compound like NASCAR’s PJ1 resin adds to the uncertainty of overtaking possibilities. The success of a dedicated practice session to rubber in the higher line at Iowa will likely determine the quality of overtakes in the upcoming race. The new hybrid unit and harder tires raise questions about the potential impact of speed increases on tire wear and overall race dynamics.
