Ninth in Detroit Grand Prix Simpson finished ninth in Sunday's NTT IndyCar Series Chevrolet Detroit Grand Prix. Impact Sunday's ninth-place result would be the best finish of Simpson's season and his third Top-10 finish of 2026. The result was especially impressive because Simpson had to serve a drive-through penalty early on after spinning out Graham Rahal. Next on the schedule is a trip to Gateway, where Simpson finished 15th in 2025 after crashing out of his first race at the track in 2024.
