Portland International Raceway Circuit

Portland International Raceway spans 1.964 miles with 12 turns carved into natural terrain. The circuit remains relatively flat compared to other road courses. Drivers navigate the Shelton Chicane at the end of the front straight, which creates one of several key passing zones. Turn 7 provides another hard-braking opportunity leading onto the sweeping backstretch. A three-turn complex returns cars to the main straight. The City of Portland owns this FIA Grade 2 facility, and the main straight doubles as a drag racing venue.

The NTT IndyCar Series features competitive teams and talented drivers. Team Penske, Chip Ganassi Racing, Arrow McLaren, and Andretti Global field multiple entries among the established organizations. Chevrolet and Honda supply engines to the series, continuing their multi-year commitments. The spec Dallara DW12 chassis provides the foundation for competition. Katherine Legge will compete with A. J. Foyt Racing in partnership with HMD Motorsports, while Jacob Abel returns with Abel Motorsports. The INDY NXT by Firestone series showcases developing talent moving up the racing ladder.

Technical Updates for 2026

Tire Regulations

Teams must use Firestone's alternate tire compounds twice during every street course race. The primary compound requires one use per race. Drivers must complete two green-flag laps on each alternate set and the primary set. This rule adds strategic elements to race planning.

Safety Developments

New superspeedway flaps have been developed for rear tire ramps. These flaps deploy during spins or rearward movement to reduce the chance of cars becoming airborne. The Indianapolis 500 requires these safety devices.

Practice Session Format

Road and street courses now use a revised practice format. The second practice session mirrors the group format of the first practice. The field splits by odd and even numbered pit boxes. An initial 40-minute segment leads into two 12-minute group segments.

Race Officiating Structure

IndyCar Officiating, a new independent, not-for-profit organization, oversees all competition officiating. A three-person Independent Officiating Board governs this organization. This structure aims to standardize race control decisions.

Event History and Legacy

The Grand Prix of Portland first ran in 1984 as a CART series race. Al Unser Jr. won that inaugural event. The race continued until 2007, then took a hiatus until returning to the IndyCar Series calendar in 2018. Green Savoree Racing Promotions serves as the current event promoter. Michael Andretti holds three victories at Portland International Raceway. Team Penske leads all teams with nine wins. Chevrolet engines and Lola chassis have earned the most manufacturer victories.

Track Records and Notable Moments

Portland International Raceway has produced some of the closest finishes in IndyCar road course history. In 1986, Mario Andretti beat his son Michael by just 0.070 seconds. The 1997 race delivered a three-wide finish, with Mark Blundell defeating Gil de Ferran by 0.027 seconds and Raul Boesel by 0.055 seconds. This remains the record for the closest two-car and three-car finish in CART/IndyCar road course competition.

The Vanport Story

Portland International Raceway sits on the former site of Vanport, Oregon. This city was built quickly in 1942 to house World War II shipyard workers. Vanport became Oregon's second-largest city at its peak. A flood destroyed the entire city on May 30, 1948. The first races on the abandoned Vanport roads took place in 1961. The Portland Parks and Recreation Department operates the track as a designated city park.

Economic Impact

Portland International Raceway generates approximately 700 jobs and contributes an estimated $45 million to the local economy each year. The facility operates as a self-sufficient entity without public funding for operations. This makes the venue a valuable asset for Portland, Oregon.
