ARCA Menards Series West races at 4 p.m. PT Friday
PORTLAND, Ore. (August 27, 2025) – The fourth annual Pacific Office Automation 147 at Portland International Raceway (PIR) will feature star-studded lineups for both the ARCA Menards Series West race Friday at 4 p.m. PT and then NASCAR Xfinity Series starting field Saturday at 4:30 p.m. PT.
On Friday, fans can enjoy PRO3 BMW E30 racing plus an ARCA Menards Series West autograph session, practice, qualifying and a 57-lap race. When the green flag drops on the race, former NASCAR Cup Series driver and Vancouver, Wash. native Greg Biffle, La Center, Wash. resident Eric Johnson, Jr. and the rest of the ARCA Menards Series West drivers, featuring an entry list of 19 cars, will battle for 112.29 miles on the 1.97-mile, 12-turn PIR track.
Saturday the NASCAR Xfinity Series takes the track for practice and qualifying, and the final 75-lap race on the weekend schedule, plus a driver autograph session is set for 2:30 p.m. PT in the Fan Zone. The 2025 Pacific Office Automation 147 will boast a competitive field of 37 cars with a number of notable drivers including 2024 NASCAR Xfinity Series Champion Justin Allgaier (JR Motorsports), Sheldon Creed (Haas Factory Team), Jesse Love (Richard Childress Racing), William Sawalich (Joe Gibbs Racing) and Connor Zilisch (JR Motorsports). The field will also have an international flavor again with entries from Australian Supercars aces Jack Perkins (Joe Gibbs Racing) and Will Brown (Kaulig Racing).
The 19-year-old Zilisch, a rising star of the sport, currently ranks second in the season point standings and was recently announced to race full-time in the NASCAR Cup Series in 2026. Allgaier, the current series points leader, won two of the three stages in the 2024 Pacific Office Automation 147 and finished second behind last year’s race winner Shane van Gisbergen. He also finished second in the 2023 race at PIR.
“As a driver, I think the race track is just a lot of fun. It’s a great facility. It’s somewhere that I think the racing is just phenomenal,” said Allgaier. “The racetrack is laid out in a way that is super fun to drive but also can be challenging and tricky, and you have to be on your A-game.”
Also on Saturday, fans can enjoy live music from the bands Hit Machine and Wrangler. Wrangler, a country spin off band which infuses a modern twist and energetic approach to country music, will be performing at 2 p.m. PT. The Northwest’s premier and longest-running band in the region, Hit Machine, will be performing at 11 a.m. PT and 6:30 p.m. PT with a setlist of musical chart toppers for all ages.
