Scott McLaughlin’s No. 3 Team Penske Chevy, Scott Dixon’s No. 9 and Takuma Sato’s No. 11 Chip Ganassi Racing Hondas, Kyle Kirkwood’s No. 27 Andretti Autosport Honda and No. Agustin Canapino’s No. 78 Juncos Hollinger Racing Chevy all installed their fifth engines of the season, and per IndyCar’s rules, only the four engines included in each annual lease are permitted for use without consequence.
