NTT INDYCAR SERIES Notes:

• The Chevrolet Detroit Grand Prix presented by Lear will be the third INDYCAR SERIES race held on the nine-turn, 1.645-mile downtown Detroit street circuit and the 35th INDYCAR SERIES race held in the Motor City. A 2.5-mile street circuit in downtown Detroit hosted CART events from 1989-91 before the event moved to Belle Isle Park in 1992.
• Scott Dixon has four wins in Detroit, the most wins by an INDYCAR SERIES driver in the Detroit Grand Prix. Dixon won three times at the Raceway at Belle Isle Park and on the streets of downtown Detroit last year. In addition to Dixon, other previous Detroit Grand Prix race winners entered include Alex Palou (2023), Will Power (2014 Race #1, 2016 Race #2, 2022), Pato O’Ward (2021 Race #2), Marcus Ericsson (2021 Race #1), Josef Newgarden (2019 Race #1) and Graham Rahal (2017 Race #1 and Race #2).

• The driver who has gone on to win the championship has won at Detroit eight times. Alex Palou won on the streets of downtown Detroit in 2023, Josef Newgarden won Race #1 on Belle Isle in 2019, Scott Dixon won Race #1 on Belle Isle in 2018, Will Power won on Belle Isle in 2022 and won Race #2 on Belle Isle in 2014, Alex Zanardi won on Belle Isle in 1998, Bobby Rahal won at Belle Isle in 1992, and Emerson Fittipaldi won in downtown Detroit in 1989.
• Milestones: Scott Dixon will attempt to make his 346th consecutive start, extending his record streak…Dixon passed Mario Andretti for the all-time in INDYCAR SERIES starts with his 408th start May 25 at Indianapolis and will extend his record with a start Sunday.

INDY NXT by Firestone Notes:

• The ultra-competitive INDY NXT by Firestone season resumes with a downtown Detroit street circuit event. Dennis Hauger leads the point standings on the strength of three wins in the first four races, but the other race winner this season, Hauger’s Andretti Global teammate Lochie Hughes, is hot on the Norwegian’s heels for the title and the financial benefits to advance to the NTT INDYCAR SERIES.
• Group qualifying will decide the starting grid on road and street circuits. Based on the best lap times from the practice session immediately preceding qualifying, the fastest driver in that session will choose which group will compete in the first of the two qualifying sessions. With 12 minutes allotted for each group (with a guarantee of one timed lap), the fastest driver between the two sessions will be awarded pole position with the drivers who finished behind that driver, in order and in that group, occupying the odd-numbered starting positions (3, 5, 7, etc.) for the race and the drivers who finished in order from the other group occupying the even-numbered starting positions (2, 4, 6, etc.). One driver and entrant championship point will be awarded to the fastest car in each qualifying group.
