The '''Grand Prix of Portland''' (known as the '''BitNile.com Grand Prix of Portland''' for sponsorship reasons) is a race in the [[IndyCar Series]] held at the [[Portland International Raceway]] in [[Portland, Oregon]]. The race was an annual event from 1984 to 2007, initially as a race in the [[Championship Auto Racing Teams|CART]] series, and later as part of the [[Champ Car World Series]]. After a ten-year hiatus, the race made its return to the IndyCar Series in the [[2018 IndyCar Series|2018 season]].<ref>{{cite news|title=IndyCar racing will return to Portland International Raceway on Labor Day weekend 2018|url=http://www.oregonlive.com/sports/index.ssf/2017/10/indycar_racing_returns_to_port.html|first=Molly|last=Blue|work=[[The Oregonian]]|publisher=[[Advance Publications]]|date=October 12, 2017|access-date=October 12, 2017}}</ref>

[[American open-wheel car racing|Championship car racing]] first appeared in the Portland area in June of 1909, at the 14.6-mile Portland Road Race Course. Two 3-lap races were held, followed by a 7-lap main event titled the Wemme Cup, which was won by [[Bert Dingley]]. 

Portland is best-remembered as being the site of two of the closest finishes on a [[Road racing|road course]] in [[American Championship car racing|Indy car racing]] history. In 1986, [[Michael Andretti]] lost fuel pressure on the final turn of the final lap, which allowed his father [[Mario Andretti|Mario]] to catch up and beat him to the finish line by 0.070 seconds. At the time, it was the closest finish of any race in Indy car history. In 1997, in a three-wide finish, [[Mark Blundell]] beat second place [[Gil de Ferran]] by 0.027 seconds, and beat third place [[Raul Boesel]] by 0.055 seconds. For a road course race, it was the all-time closest finish in CART series history, as well as the closest three-car finish in series history.

For nearly its entire existence, the title sponsor of the race was sporting goods retailer [[G.I. Joe's]] and took place in June, during or around the [[Portland Rose Festival]]. Numerous times, the race was held on [[Father's Day (United States)|Father's Day]]. From 2018-2024, the race was held in September (late August in 2024) on or around [[Labor Day]] weekend. Since returning to the calendar, the race has been promoted by [[Kim Green (racing driver)|Green Savoree Racing Promotions]].

*'''1985''': [[Mario Andretti]] passed [[Al Unser Jr.]] for the lead with 19 laps to go, and pulled out to a 25-second victory. Unser Jr. led 49 laps, but after his final pit stop, a bad set of tires and fuel concerns forced him to slow his pace. Andretti was trailing by nearly 15 seconds, but a fast final pit stop, and handling adjustments allowed him to quickly close the gap and drive to victory. It was his second win in a row, and his third victory of the 1985 season. Indy 500 winner [[Danny Sullivan]] started on the pole position, but dropped out on lap 6 due to steering failure.<ref name="Star06-17-1985pg17">{{cite news|title=Mario overhauls Unser at Portland|url=https://www.newspapers.com/clip/17207950/1985_cart_portland/|newspaper=The Indianapolis Star|page=17|via=[[Newspapers.com]]|date=June 17, 1995|access-date=February 6, 2018}}{{Open access}}</ref>
*'''1986''': In one of the most dramatic finishes in [[Championship Auto Racing Teams|CART]] history, [[Mario Andretti]] beat his son [[Michael Andretti]] to the finish line by 0.07 seconds. It was the closest finish in Indy car racing history at the time. With ten laps to go, Michael led Mario by over eight seconds, and looked to be on his way to a dominating victory. [[Al Unser Jr.]] was in third position right on the back bumper of Mario. In the closing laps, however, Michael began experiencing fuel pickup problems. Mario and Unser Jr. were charging, and began trimming the lead. At the white flag, Michael still led by three seconds, but his engine was sputtering. As the cars came off the final corner, Michael's engine quit and he began to coast down the inside of the frontstretch. Mario and Unser Jr. raced to the finish line, and Mario nipped Michael at the line by about two feet. Unser came home a close third. In victory lane, a dejected Michael Andretti declared the win a [[Father's Day (United States)|Father's Day]] gift for Mario.<ref name="Star06-15-1986pg21">{{cite news|title=Mario gets gift, title from Michael (Part 1)|url=https://www.newspapers.com/clip/17208233/1986_cart_portland/|first=Robin|last=Miller|author-link=Robin Miller (journalist)|newspaper=The Indianapolis Star|page=21|via=[[Newspapers.com]]|date=June 15, 1986|access-date=February 6, 2018}}{{Open access}}</ref><ref name="Star06-15-1986pg22">{{cite news|title=Mario gets gift, title from Michael (Part 2)|url=https://www.newspapers.com/clip/17208275/1986_cart_portland/|first=Robin|last=Miller|author-link=Robin Miller (journalist)|newspaper=The Indianapolis Star|page=22|via=[[Newspapers.com]]|date=June 15, 1986|access-date=February 6, 2018}}{{Open access}}</ref>
*'''1987''': [[Roberto Guerrero]] started on the pole position, but [[Emerson Fittipaldi]] got the jump at the start and took the lead on the first lap. Fittipaldi led 45 of the first 46 laps until a blown engine ended his day. Guerrero also dropped out early with engine failure. [[Bobby Rahal]] took the lead, and led 56 of the final 58 laps to score his first victory of the 1987 season. Rahal built up a lead of over 23 seconds, and lapped all but second place [[Michael Andretti]].

*'''1988''': [[Danny Sullivan]] started the race on the pole position, and led the first 13 laps. But as Sullivan was making his way through traffic on lap 14, he nearly clipped wheels with [[Rocky Moran]] and did a half spin to the infield grass. [[Arie Luyendyk]] slipped by to take the lead, and [[Al Unser Jr.]] took over second. Sullivan dropped to third, but the car was undamaged. Luyendyk led 53 laps and appeared poised to win his first Indy car race. With Luyendyk, Unser, and Sullivan running 1st-2nd-3rd, the leaders prepared for their final pit stop. Luyendyk pitted on lap 69, and Unser pitted on lap 70. Unser's pit stop lasted 32 seconds due to a problem with the left rear wheel, and he dropped out of contention. Sullivan pitted on lap 71. The Penske Team's lightning-fast pit stop put Sullivan out ahead of Luyendyk, and Sullivan drove to victory. Luyendyk finished second, his best career finish at the time, but his pace was slowed at the end after he lost third gear.<ref name="Star06-20-1988pg18">{{cite news|title=Sullivan captures CART race in pits|url=https://www.newspapers.com/clip/17266492/1988_cart_portland/|newspaper=The Indianapolis Star|page=18|via=[[Newspapers.com]]|date=June 20, 1988|access-date=February 8, 2018}}{{Open access}}</ref>
*'''1989''': [[Teo Fabi]] scored the first pole position for the [[Porsche in motorsport#Indycars|Porsche Indy Car team]], and led 17 laps, en route to a fourth-place finish. [[Emerson Fittipaldi]] won the race, crossing the finish line just seconds before his car ran out of fuel. [[Bobby Rahal]] finished second, and gave Fittipaldi a ride back to the pits on his sidepod. Minor mishaps made for a wild afternoon, including the asphalt pavement breaking up in the chicane, and a water main break that threatened to flood some of the pit stalls. [[Scott Pruett]] tangled with [[Al Unser Jr.]] in the chicane on lap 65, sending Unser into the tire barrier with a broken rear wing. Later, Pruett spun out on his own, right in front of Unser, prompting Unser to clap in celebration. [[Geoff Brabham]] was driving in substitute for [[Danny Sullivan]] who was still recovering from a broken arm at Indianapolis. Brabham was running second with 14 laps to go when radiator problems put him out.<ref name="Star06-26-1989pg13">{{cite news|title=Fittipaldi (again) wins at Portland (Part 1)|url=https://www.newspapers.com/clip/17266659/1989_cart_portland/|newspaper=The Indianapolis Star|page=13|via=[[Newspapers.com]]|date=June 26, 1989|access-date=February 8, 2018}}{{Open access}}</ref><ref name="Star06-26-1989pg14">{{cite news|title=Fittipaldi (again) wins at Portland (Part 2)|url=https://www.newspapers.com/clip/17266777/1989_cart_portland/|newspaper=The Indianapolis Star|page=14|via=[[Newspapers.com]]|date=June 26, 1989|access-date=February 8, 2018}}{{Open access}}</ref>

*'''1990''': [[Michael Andretti|Michael]] and [[Mario Andretti]], now teammates at [[Newman Haas Racing]], finished 1st-2nd for the second time in an Indy car race. It was the second time it occurred at Portland (after 1986), though this time Michael finished on top.

*'''1991''': [[Michael Andretti]] made a daring pass at the start of the race, and grabbed the lead from the fourth starting position. Andretti would go on to lead all but two laps, and won at Portland for the second consecutive year. As the field came down the frontstretch to take the green flag, Michael Andretti darted to the middle to pass [[Scott Pruett]], then the field fanned out five-wide. Andretti narrowly squeezed between [[Rick Mears]] and pole-sitter [[Emerson Fittipaldi]] and emerged with the lead in the chicane. [[Emerson Fittipaldi]] finished second. Andretti's only tense moment of the day came around the halfway point. He became mired behind the lapped car of [[Truesports]] driver [[Scott Pruett]], which allowed Fittipaldi to close within a few seconds. Pruett, who qualified third and finished eight, had a decent run in the [[Rahal-Hogan RH-001|Truesports 91C]] chassis, holding off Andretti for many laps, but was noticeably down on power with the [[Judd (engine)|Judd AV]] engine.<ref name="Star06-24-1991pg9">{{cite news|title=Michael Andretti wows 'em for Portland win (Part 1)|url=https://www.newspapers.com/clip/17388869/1991_cart_portland/|first=Bob|last=Baum|newspaper=The Indianapolis Star|page=9|via=[[Newspapers.com]]|date=June 24, 1991|access-date=February 12, 2018}}{{Open access}}</ref><ref name="Star06-24-1991pg10">{{cite news|title=Michael Andretti wows 'em for Portland win (Part 2)|url=https://www.newspapers.com/clip/17389113/1991_cart_portland/|first=Bob|last=Baum|newspaper=The Indianapolis Star|page=10|via=[[Newspapers.com]]|date=June 24, 1991|access-date=February 12, 2018}}{{Open access}}</ref>
*'''1992''': For the third year in a row, [[Michael Andretti]] won in dominating fashion. Andretti took the lead at the start and led 100 of 102 laps.

*'''1993''': [[Nigel Mansell]] started from the pole, and led the first 27 laps. In fierce battle with [[Emerson Fittipaldi]], Mansell locked up the brakes on lap 28 going into the Festival Curves, and slid off-course into a row of cones and into the runoff area. Mansell kept the engine running, and re-joined the race, but Fittipaldi was now the leader. The skies opened up on lap 45, soaking the course, and forced the teams to switch to rain tires for the next 25-30 laps. Fittipaldi led 70 of the final 75 laps, and won for the second time at Portland.

*'''1996''': Rookie [[Alex Zanardi]] won his first CART series race, leading 88 of the 102 laps. About 30 laps into the race, a rain shower swept over the track, but Zanardi elected not to switch to rain tires. His 17-second lead evaporated, and [[Al Unser Jr.]] passed Zanardi for the lead on lap 39. The lead was short-lived, as Unser's rain tires began to fall off. Two laps later, Zanardi was back in the lead, and the rain soon stopped.

===CART Fedex Championship Series===
[[File:Mark Blundell portrait 2011.jpg|thumb|[[Mark Blundell]]'s dramatic victory in 1997 was the closest 1-2-3 finish in CART series history at the time.]]
*'''1997''': The race was the closest finish in the history of the CART series on a [[Road racing|road course]], as well as the closest three-car finish of any Indy car race at the time. Rain fell most of the day, making for a slick track, resulting in several spins and numerous off-course excursions. Late in the race, [[Gil de Ferran]] led with [[Christian Fittipaldi]] close behind in second, but the race was approaching the two-hour time limit. With the track slowly starting to dry, some teams elected gamble and change to [[Racing slick|slick tires]]. [[Paul Tracy]], [[Maurício Gugelmin]], [[Alex Zanardi]], and others all came out on slicks and proceeded to spin off course. On lap 68 [[Mark Blundell]] also switched to slicks, and he too attempted to chase down the leaders. The race was set to end early at the completion of lap 78. With two laps to go, Blundell had caught up to de Ferran and Fittipaldi, but was carefully trying to maneuver around traffic and stay on course. Blundell passed Fittipaldi for second in turn ten. Meanwhile, [[Raul Boesel]] was closing in on the leaders as well. The white flag was raised by Gil de Ferran as Mark Blundell pursued him. On the last lap, de Ferran struggled mightily to keep Blundell at bay as they were nose-to-tail and side by side. Boesel slipped by Fittipaldi for third place in turn nine, and quickly closed in behind the two leaders. Coming off the final turn of the final lap, the finish became a three-wide drag race between de Ferran, Blundell, and Boesel. Mark Blundell nosed ahead at the finish line and beat Gil de Ferran by 0.027 seconds. Boesel crossed the finish line third, only 0.055 seconds behind. it was Blundell's first CART series victory, and first professional win since the [[1992 24 Hours of Le Mans]].<ref name="Star06-23-1997pg13">{{cite news|title=Blundell slips to his first CART victory (Part 1)|url=https://www.newspapers.com/clip/17474571/1997_cart_portland/|first=Dick|last=Mittman|newspaper=The Indianapolis Star|page=13|via=[[Newspapers.com]]|date=June 23, 1997|access-date=February 15, 2018}}{{Open access}}</ref><ref name="Star06-23-1997pg15">{{cite news|title=Blundell slips to his first CART victory (Part 2)|url=https://www.newspapers.com/clip/17474647/1997_cart_portland/|first=Dick|last=Mittman|newspaper=The Indianapolis Star|page=15|via=[[Newspapers.com]]|date=June 23, 1997|access-date=February 15, 2018}}{{Open access}}</ref>
*'''1998''': At the start, [[Greg Moore (racing driver)|Greg Moore]]'s car veered to the inside, then wildly hopped the curbing going into the Festival Curves. Moore crashed out himself along with [[Paul Tracy]] and [[Christian Fittipaldi]]. At least four other cars were involved, including [[Michael Andretti]] who was hit and stalled in the gravel trap. Polesitter [[Bryan Herta]] led the first 13 laps, but his [[Rahal Letterman Lanigan Racing|Team Rahal]] crew decided to pit during a caution on lap 14 and make it a three-stop race. The pit strategy backfired, however, and Herta spent most of the day trying to catch back up to the lead. [[Alex Zanardi]], utilizing a two-stop strategy, was leading the race when [[Dario Franchitti]] had a frightening crash on lap 73. Franchitti clipped wheels with [[P. J. Jones]], and slammed into the outside barrier near turn ten. Herta immediately ducked into the pits during the resulting caution, and bunched up behind Zanardi for the subsequent restart. Zanardi got the jump on the restart, while Herta was held up behind the lapped car [[Richie Hearn]]. [[Gil de Ferran]] pounced on Herta, but the two cars tangled in the Festival Curves. [[Scott Pruett]] slipped by to take second, while Zanardi went on to win. Herta recovered to finish third.<ref name="Star06-22-1998pg20">{{cite news|title=Strategy in pits helps Zanardi win 4th race this year|url=https://www.newspapers.com/clip/17591977/1998_cart_portland/|first=Bob|last=Baum|newspaper=The Indianapolis Star|page=20|via=[[Newspapers.com]]|date=June 22, 1998|access-date=February 19, 2018}}{{Open access}}</ref>
*'''1999''': With most teams employing a two-stop, fuel conservation strategy, [[Gil de Ferran]] of [[Walker Racing]] decided to scuttle the fuel conservation and drive all-out for the lead. He would need three pit stops, and would have to hope for no full-course caution periods during his final stint. With less than ten laps to go, de Ferran had built up a 29-second lead over second place [[Juan Pablo Montoya]], but needed one final pit stop for fuel. On lap 90, de Ferran came in for a splash-and-go stop for fuel, and remarkably came out on the track still seven seconds ahead of Montoya. Gil de Ferran held on over the final 8 laps and scored his first CART series victory in three years, and the first win for [[Walker Racing]] since [[Robby Gordon]] at [[Detroit Grand Prix (IndyCar)|Detroit]] in [[1995 PPG Indy Car World Series|1995]].<ref name="Star06-21-1999pg10">{{cite news|title=Risky strategy in pits plays off for de Ferran|url=https://www.newspapers.com/clip/17592100/1999_cart_portland/|first=Mike|last=Harris|newspaper=The Indianapolis Star|page=10|via=[[Newspapers.com]]|date=June 21, 1999|access-date=February 19, 2018}}{{Open access}}</ref>
*'''2000''': In an effort to take fuel strategy off the table, the race was lengthened from 98 to 112 laps. One driver, however, [[Roberto Moreno]], still attempted to finish the race with only two pit stops. [[Gil de Ferran]], now with [[Penske Racing]], mimicked his strategy from the previous year, and raced all-out, all along planning three pit stops. In the closing laps, the leaders started cycling through a series of splash-and-go pit stops. Gil de Ferran pitted on lap 89, while race leader [[Hélio Castroneves]] pitted on lap 105. The lead went to Gil de Ferran, while Moreno stayed out and moved up to second. The victory went to de Ferran, his second consecutive win at Portland. After leading 85 laps, Castroneves ran out of fuel on the final lap and finished a distant 7th place.<ref name="Star06-26-2000pg25">{{cite news|title=De Ferran strategy pays off in victory (Part 1)|url=https://www.newspapers.com/clip/17625924/2000_cart_portland/|first=Robin|last=Miller|author-link=Robin Miller (journalist)|newspaper=The Indianapolis Star|page=25|via=[[Newspapers.com]]|date=June 26, 2000|access-date=February 20, 2018}}{{Open access}}</ref><ref name="Star06-26-2000pg26">{{cite news|title=De Ferran strategy pays off in victory (Part 2)|url=https://www.newspapers.com/clip/17625952/2000_cart_portland/|first=Robin|last=Miller|author-link=Robin Miller (journalist)|newspaper=The Indianapolis Star|page=26|via=[[Newspapers.com]]|date=June 26, 2000|access-date=February 20, 2018}}{{Open access}}</ref>
*'''2001''': Steady rain made for a slippery course, resulting in several spins and crashes, and nine caution periods. The race was shortened from 98 to 76 laps due to the two-hour time limit, and [[Max Papis]] emerged as the winner. Papis started on the pole position and avoided all the melees, and made only one pit stop en route to victory. Papis held off [[Roberto Moreno]], who finished second at Portland for the second year in a row.<ref name="Star06-25-2001pg20">{{cite news|title=Papis starts up front and finishes there|url=https://www.newspapers.com/clip/17626187/2001_cart_portland/|first=Landon|last=Hall|newspaper=The Indianapolis Star|page=20|via=[[Newspapers.com]]|date=June 25, 2001|access-date=February 20, 2018}}{{Open access}}</ref>
*'''2002''': [[Cristiano da Matta]] started from the pole, but [[Kenny Bräck]] grabbed the lead at the start. Brack controversially caused the start to be waved off three times for not being properly in line. Then on the fourth start attempt, a collision deep in the field sent three cars spinning and three to the escape road. Brack led 55 of the first 59 laps. On lap 60, Brack, [[Cristiano da Matta]], and [[Bruno Junqueira]] all came in the pits, running 1-2-3. Brack came out first, but while accelerating into the Festival Curves, lost the left rear wheel which was not properly fastened. Cristiano de Matta led the rest of the way, holding of Junquiera by 0.625 seconds for the victory.<ref name="Star06-17-2002pg28">{{cite news|title=Da matta goes to battle with Junqueira for win|url=https://www.newspapers.com/clip/17659364/2002_cart_portland/|newspaper=The Indianapolis Star|page=28|via=[[Newspapers.com]]|date=June 17, 2002|access-date=February 21, 2018}}{{Open access}}</ref>
*'''2003''': [[Adrián Fernández]] passed [[Paul Tracy]] going into the Festival Curves on lap 86, and drove to victory, the first CART series win by an owner/driver since 1992. The pass came one lap after a restart, and Tracy came home second. Tracy started on the pole position and led 42 laps, but he was penalized on lap 44 for a pit exit infraction. In a battle for the lead with [[Michel Jourdain Jr.]], Tracy cut off Jourdain in the pit lane, swinging out of his pit box directly to the outside fast lane, which was against the rules. One lap later, Jourdain and Tracy went side by side into the Festival Curves, and locked wheels, sending Jourdain spinning and out of contention.<ref name="Star06-23-2003pg21">{{cite news|title=Fernandez helps his cause (Part 1)|url=https://www.newspapers.com/clip/17685176/2003_cart_portland/|first=Andrew|last=Hinkleman|newspaper=The Indianapolis Star|page=21|via=[[Newspapers.com]]|date=June 23, 2003|access-date=February 22, 2018}}{{Open access}}</ref><ref name="Star06-23-2003pg26">{{cite news|title=Fernandez helps his cause (Part 2)|url=https://www.newspapers.com/clip/17685229/2003_cart_portland/|first=Andrew|last=Hinkleman|newspaper=The Indianapolis Star|page=26|via=[[Newspapers.com]]|date=June 23, 2003|access-date=February 22, 2018}}{{Open access}}</ref>

===IndyCar Series===
*'''2018''': After a ten-year absence, Portland returned to the Indy car calendar. Will Power won the pole for the return race, breaking [[Justin Wilson (racing driver)|Justin Wilson]]'s track record from 2005. On the first corner, [[Zach Veach]] gave [[James Hinchcliffe]] no room and spun him out into traffic including drivers [[Ed Jones (racing driver)|Ed Jones]], [[Graham Rahal]], [[Scott Dixon]], and [[Marco Andretti]] who went up on the wheels of Hinchcliffe and went over him and Ed Jones and landing on his top. Scott Dixon stopped and hit nothing and continued on, amazingly he finished the race fifth. In the end after [[Alexander Rossi]] and [[Josef Newgarden]] dominated the race, an untimely caution came out and shuffled the field around. [[Max Chilton]] stayed out and led a few laps before pitting late, giving the lead to [[Takuma Sato]], he led the final laps while conserving push to pass seconds and holding off [[Ryan Hunter-Reay]] who was charging at the end. It was Sato's first win on a permanent road course and first since his [[2017 Indianapolis 500]] win.
*'''2019''': Colton Herta started on pole but the race was won by Will Power with Felix Rosenqvist finishing second and Alexander Rossi third.
