Scott McLaughlin will have a new strategist and engineer for the Indianapolis 500 because of a rules infraction that concerned a part on Team Penske cars other than his own, and that has left him both angrily defensive and utterly motivated.

Team Penske's IndyCar team will enter Sunday's Indy 500 without its three most senior leaders and each of its cars' strategists in the wake of the program's Indy 500 qualifying scandal.

The 109th running of the Indianapolis 500 is this Sunday at Indianapolis Motor Speedway. See who the experts and oddsmakers predict to win.

The 109th running Sunday is loaded with storylines, from Team Penske firings to cars failing inspections, Shwartzman making history and Newgarden’s 3-peat bid.

He won the pole with Italian team Prema Racing, a dominant European organization that this season expanded to IndyCar. Shwartzman has never before raced on an oval and will start alongside two-time winner Takuma Sato and Pato O’Ward, who lost to Newgarden on the last lap year.
