Changes to Improve Iowa Speedway Races
After the least exciting races at Iowa Speedway since IndyCar began racing on the 0.875-mile track in 2007, the series has implemented a variety of modifications to the technical specifications of the Dallara DW12s to enhance this weekend’s event.
Doubleheader Details
The upcoming doubleheader will feature two 275-lap races, one on Saturday night and the other on Sunday afternoon. Teams will utilize a revised version of the technical specifications that were tested during a recent session at the short oval, which was repaved in 2024.
Aim for Improved Racing
Last year, cars predominantly ran single-file along the lower lane due to a lack of grip in the second lane. To address this issue, IndyCar is working to create more overtaking opportunities by modifying the cars’ downforce through the aerodynamic setup designed for road courses and short ovals.
Changes in Downforce Strategy
During the 2024 doubleheader, teams were permitted to use barge boards and strakes to enhance downforce efficiency. However, these features are banned for 2025, leading to a stronger dependence on top-side downforce generated by the less efficient front and rear wings to make up for lost downforce.
Enhancements and Tire Changes
By adjusting downforce to the wings, IndyCar hopes the increase in drag will assist trailing cars in overtaking. A modification from the test concerning rear wing adjustments has reduced overall downforce by around 275 pounds. Additionally, teams will use the lowest turbocharger boost setting similar to that used in the Indy 500 to optimize performance.
Safety Improvements Following Crashes
During recent tests, Ed Carpenter Racing’s Christian Rasmussen experienced a significant crash due to a burst right-front tire. Consequently, a more robust right-front tire is being introduced for the doubleheader, along with a differentiated tire plan to enhance durability.
Driver Insights and Predictions
Kyle Kirkwood from Andretti Global, who won the latest oval race, expressed cautious optimism but highlighted concerns that the racing dynamics may mirror those of 2024. Josef Newgarden from Team Penske, a multiple-time winner at Iowa, echoed similar sentiments, suggesting that limiting downforce could allow for better racing. Both drivers stress the need to encourage the use of the second lane for an enhanced racing experience.
