The Portland ePrix (known as the Southwire Portland ePrix then Hankook Portland ePrix for sponsorship reasons) was an annual race of the FIA Formula E World Championship, an all-electric single-seater racing series. The race was held on a very slightly modified version of the Portland International Raceway (PIR) for the first time in 2023, and again in 2024.[1] Nick Cassidy won the inaugural race for Envision Racing,[2] while António Félix da Costa and Porsche swept both races the following year.
After construction in the Red Hook area of Brooklyn caused the New York City ePrix to be taken off the calendar for 2023, Formula E signed a deal with the City of Portland and PIR in order to keep the American interest in Formula E alive over the stop-gap period in New York. FE co-founder Alberto Longo said that the Portland motorsports fanbase and the city's "ecological credentials" were vital in choosing the city to play host to Formula E.[3] The ePrix was the first of its kind in the Pacific Northwest, the first ePrix on the US West Coast since the 2015 Long Beach ePrix, and the fourth United States ePrix following Long Beach, NYC, and the Miami ePrix.
The Portland International Raceway was home to the event,[4] and unlike other FE races at permanent circuits such as Valencia, there were no major changes to the circuit layout (although the barrier at the entrance to the Shelton Chicane was extended to tighten Turn 1). With the ePrix debuting in 2023, this marked the third auto race held at PIR alongside IndyCar's Grand Prix of Portland and the NASCAR Xfinity Series Pacific Office Automation 147.
