The Pacific Office Automation 147 was a NASCAR Xfinity Series race that was held at the Portland International Raceway road course in Portland, Oregon. Connor Zilisch was the final winner of the event.
History A NASCAR Camping World Truck Series race was previously held at this track in 1999 and 2000. The Xfinity Series race at Portland marked the first time since then that a NASCAR national series has had a race in the Pacific Northwest.
On September 18, 2021, Elizabeth Blackstock from Jalopnik reported that there were rumors of the track hosting an Xfinity Series race and a Truck Series race in 2022. On September 25, Jordan Bianchi from The Athletic reported that Portland would likely be on the 2022 Xfinity Series schedule. The schedule was released on September 29 with Portland on Saturday, June 4. It replaced the race at the Mid-Ohio Sports Car Course. Both the Mid-Ohio and Portland races were promoted Green Savoree Racing Promotions. Mid-Ohio was given a Truck Series race after losing their Xfinity Series date.
The race was 147 miles and 75 laps long according to NASCAR.com. Each of the stages will be 25 laps in length.
On April 19, 2022, the track announced that Pacific Office Automation, a company located in nearby Beaverton, Oregon that makes technology for office space, would be the title sponsor of the race.
The race was dropped from the schedule following the 2025 season.
