The Canyonero is a massive red SUV with deep blue tinted windows. It has a pair of cross bars on the roof and is adorned with chrome trimming along the bottom edges. A single side step accompanies each side to compensate for the car's huge lift. Finally, in the back portion of the vehicle there appears to be a large amount of groceries contained in the back. When accessed during Level 2, Level 5, Level 6, and Level 7, Marge appears in the driver's seat. The car bears a strong resemblance to the real life 1968 Jeep Wagoneer.
The Canyonero makes its first appearance in Level 1. Homer tells Marge about his theory that Mr. Burns is spying on Springfield. Marge dismisses him, and manages to pull Homer on board a scheme to destroy as many copies of Bonestorm II as she can. The two drive the Canyonero for this mission. In Level 3's circuit and checkpoint races, Marge is the top opponent Lisa must defeat. Marge can be seen in these races driving the Canyonero. Once the player reaches Level 4 and begin playing as Marge, they unlock the Canyonero, as it is her car of choice.
- The Canyonero is a car briefly owned by Homer and then Marge Simpson in the episode "Marge Simpson in: "Screaming Yellow Honkers"".
- Like with any vehicles with a roof, Marge default hairdo will bend back as it pushes against the ceiling whenver she drives the Canyonero.
