Opening racing ("Run That Race")/Entering Jackson Storm/Chick's Picks and introducing Natalie Certain
The film begins with Lightning McQueen prepares for the biggest race, just then Mater, Thomas and the rest of the team showed up. Lightning tells them that he was preparing for the biggest race and he needs very quiet. Then, Mater, Thomas and the team agreed and get out of Lightning's trailer. Mater announces everyone that Lightning needs quiet by saying "Hey, Everybody, listen up! My best friend, Lightning McQueen, needs quiet! Perfect quiet!" and honks his horn very loudly. Back inside Lightning's trailer, Lightning chuckled and gone back to his preparing. Then, he remembers Doc Hudson, aka The Fabulous Hudson Hornet. In the flashback, Doc tells Lightning about racing. Back in present, Mack knocks on the door and tells Lightning that is her ready. Lightning was ready, opens his trailer's door and sees the picture of Doc and tells it, "This one's for you, Doc." as the song "Run that Race" begins to play.
In the Dinoco Light 350 race, Lightning was racing with the other racecars, including his long-time friends, Cal Weathers (a Dinoco racer #42 and Strip "The King" Weathers' nephew) and Bobby Swift (an Octane-Gain racer #19), as the opening titles "Ryan's, Thomas' and Crash's Adventures of Cars 3" appears. The Freeman team, Mater (wears a Lightning bolt hat), Sally Carrera, Luigi and Guido, Sarge, Fillmore, Sheriff, Ramone, Flo and the fans (including Maddy McGear) cheers Lightning on. Lightning teases Cal that his blinkers on and he passed him, Cal tells Lightning that his blinkers on and Bobby says "Good comeback, Cal!". Lightning, Cal and Bobby goes to the pit stop to refuel and tire changing while Bob Cutlass and Darrell Cartrip looked at them. After Lightning got his tires changed, he tells Cal that he is getting a car wash but he tells that he is getting a car wash and Cal's crew chief and uncle, Strip Weathers aka "The King", tells his nephew, "Good comeback, Cal.". Rainbow Dash and Human Rainbow Dash laugh at the comment. Even, Lightning won the race. While Shannon Spokes interviews with Lightning, Bobby Swift and a pitty splash Lightning with fire-extinguisher foam. In another race, Lightning and Cal were racing to the finish line and Cal wins. Shannon interviews him and as she does, Cal sees his tires blowing up like balloons. Guido appears behind Cal and
