Season 1

The five leaders for the World Race teams, Wave Rippers, Scorchers, Street Breed, Dune Ratz and Road Beasts, are chosen and are quickly sent into Highway 35 where their first challenge includes the lava-filled Volcano Track. But things heat up when Wave Ripper Lani Tam gets caught in the uncontrolable lava of the volcano.

Just as the teams get ready for the Greatest Challenge, a giant and deadly road blocking device, Kurt's younger brother Mark joins in on the adventure. But, as enthusiastic as Mark is, Kurt doesn't want his kid brother around. Fortunately, Vert is impressed by the driving ability of his rival's brother so he asks Mark to join the Wave Rippers.

Dune Ratz leader Kadeem nearly does the impossible and comes close to grabbing the Wheel of Power, which he hopes will let him win World Race and the prize that could help his people back home.

Mark Wylde faces off against his older brother Kurt Wylde through the very dangerous ice-covered mountains of Highway 35. It'll be a Wylde ride but which brother will come out on top?

Tezla finally gets his hands on the Wheel of Power but an invasion at the complex proves that someone else won't give it up with out a fight. Fortunately the World Race team leaders join forces to keep the Wheel of Power from falling into the wrong hands. A final showdown on Highway 35 ensues.
