The Pennzoil 150 was a NASCAR Xfinity Series auto race held at the Indianapolis Motor Speedway road course from 2020 to 2023.

The IndyCar Series' Grand Prix of Indianapolis was also held on the same day as this race in all four years it was run.

The Xfinity and Cup Series races at the track were moved back to the oval in 2024, reviving the Pennzoil 250 and the Brickyard 400.

After longtime NASCAR and IndyCar team owner Roger Penske purchased Indianapolis Motor Speedway from the George family in 2019, it announced on January 15, 2020 that the Xfinity Series race at Indianapolis would move from the oval to the track's infield road course.

[2] On March 26, 2020, as part of changes to the 2020 IndyCar Series schedule due to the COVID-19 pandemic, it was announced that the series' GMR Grand Prix, an IMS road course race typically held as a prelude to the Indianapolis 500, would be postponed to July 4, 2020, and this would form an IndyCar/NASCAR double-header with the Pennzoil 150.
