The 2025 Pacific Office Automation 147 was the 25th stock car race of the 2025 NASCAR Xfinity Series, and the fourth and final iteration of the event. The race was held on Saturday, August 30, 2025, at Portland International Raceway in Portland, Oregon , a 1.967 miles (3.166 km) permanent road course. The race was contested over 78 laps, extended from 75 laps due to a green-white-checkered finish. In an action-packed race, Connor Zilisch, driving for JR Motorsports, would survive a chaotic overtime restart, and continued to dominant on the road courses, winning both stages and led all but 8 laps to earn his ninth career NASCAR Xfinity Series win, his eighth of the season, and his third consecutive win. He also became the highest winning rookie driver in Xfinity Series history.[9] To fill out the podium, William Sawalich, driving for Joe Gibbs Racing, and Nick Sanchez, driving for Big Machine Racing, would finish 2nd and 3rd, respectively.

Qualifying

Perspective

Qualifying was held on Saturday, August 30, at 1:05 PM PST. Since Portland International Raceway is a road course, the qualifying procedure used is a two-group system, with one round. Drivers will be separated into two groups, A and B. Each driver will have multiple laps to set a time. Whoever sets the fastest time between both groups will win the pole.[10]

Under a 2021 rule change, the timing line in road course qualifying is "not" the start-finish line. Instead, the timing line for qualifying will be set at the exit of Turn 11. Connor Zilisch, driving for JR Motorsports, would score the pole for the race, with a lap of 1:13.380, and a speed of 96.648 mph (155.540 km/h).[12]

No drivers would fail to qualify.
