Owned by Chip Ganassi Racing, the Dallara is powered by the Honda Indy V-6 double-overhead camshaft all-aluminum engine which displaces 134 cubic inches fitted with twin BorgWarner EFR (Engineered for Racing) turbochargers. Boost pressure is regulated at 18 PSI (pounds per square inch) on super speedways except for 20 PSI boost is allowed for Indianapolis 500 qualifying. 21 ½ PSI is allowed on short ovals and road or street courses, and the push to pass feature temporarily increases boost pressure to   24 PSI for 15 to 20 seconds depending on the road or street course.
