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.
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. [1] On September 25, Jordan Bianchi from The Athletic reported that Portland would likely be on the 2022 Xfinity Series schedule. [2] 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. [3]
The race was 147 miles and 75 laps long according to NASCAR.com. [4] Each of the stages will be 25 laps in length. [5]
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. [6]
The race was dropped from the schedule following the 2025 season. [7]
