Fourth at Road America Simpson finished fourth in Sunday's NTT IndyCar Series XPEL Grand Prix at Road America. Impact Simpson's fourth-place result on Sunday is his best of the 2026 season, and it came on a day where he started back in the 19th position. He just missed out on a podium, passing Scott Dixon just after the caution flew at the end of the race. Mid-Ohio is next on the IndyCar schedule, a track where Simpson ran well in 2025, qualifying third and finishing 10th.
