The Portland International Raceway (PIR) is a motorsport complex located in the northern part of the City of Roses' metropolitan area, on a terrain lot that used to be a city, Vanport, designed for temporary wartime workers. When the city flooded in 1948, people went away, and the paved streets were left alone, capturing the attention of racers who took the streets immediately. The PIR complex includes an off-road field, a motocross track, and of course, the main raceway of 1.97 mi, almost entirely flat, an average lap time of 1:26.827, and an 82 mph speed average.
Portland's mild climate, with warm summers and high humidity during the rest of the year, makes it an ideal place to have racing competitions from spring to fall, hosting IndyCar, NASCAR, SCCA races, among others. Up to 85K spectators can watch their favorite motorsport in PIR, and with easy access from the city, a full-house is quite a possibility in every event. The circuit consists of 12 turns when using the chicane or nine turns when not. It also has several long straight segments where drivers tend to push their gas pedals to the end, making the final stretch runs very exciting to see.
See our Portland International Track Guide for more info on how to get the most out of this track.
When using the chicane, the Portland International Raceway consists of 12 turns for a total length of 1.945 miles (3.13 km). There are no significant elevation changes in the whole track, and thus the drivers have complete visibility to see competitors from long distances.
