'The World race' was a race organized by Dr.Tezla with the objective of claiming the Wheel of Power. Tezla. He aimed to do this utilizing his teams of drivers racing in 6 legs; the Volcano track, the rainforest, the desert, the Ice track, the Water track and finally, Hotwheels city. Gelorum and her Robot army are also in it to win the World race, hiring ZED-36 (Kurt Wylde) to sabotage Tezla's plans and win, but he turns on her. Vert Wheeler grabs the Wheel of Power, only to put it back later to keep it away from Clyp.
Highway 35 was built by the Accelerons eons ago as a place to race and prior to the events of the movie, Dr.Tezla found it and discovered the Wheel of Power. He theorized that it could solve many of the world's problems if he could harness the Wheel's power correctly.
