The racing realms were created by the Accelerons a long time ago. Highway 35 was just a test, but the realms were more dangerous and more prominent of a specific category of driving, like foggy weather driving or knowing what is not the right path for your car.
The racing realms were accessed through the Wheel of Power. Each realm was represented by a symbol. When a realm is about to open, the wheel's 3 rings will rotate in all directions: First the center ring will stop and make a single symbol glow. Then the next ring will have the same symbol match on top of it and the same goes for the third ring. Once that is complete the portal will open and anything going 300 mph can go in and try to complete the realm. However, the portal is only open for one hour. Anything that doesn't make it out will be trapped in the realm. If the realm is not completed then it will open again letting anything out. It is also shown if the portal is closed and a car is in between dimensions anything on the other side will be cut off leaving behind glowing hot metal, to add on further these realms suppress all powers even Silencerz or Drones can't escape.
Every realm has many hazards (such as traps and monsters) that try to prevent anyone or anything from leaving the realm. This is most explained in the Swamp Realm when giant mosquitoes, slugs, gorillas and the swamp beast were capturing drivers and guarding the portal. However, when a driver gets out first, the obstacles will be deactivated and the creatures will quit trying to capture drivers.
Each realm has a specific skill that drivers need to master if they want an easier time getting out which is the whole point the Accelerons created them. At the end of each realm, when the portal hasn't been crossed yet the symbol of the realm is shown. Whoever gets out first will have an Accelecharger appear in their car. The Accelecharger gives abilities to a car allow it to perform the skill for the corresponding realm perfectly. When all the Accelechargers are collected they combine their energy and the Wheel of Power will rotate faster and create the Ultimate Race. In the Ultimate Race the realms are brought together and the drivers will have to race through each of them starting at the first realm. The Wheel of Power will randomly go through each realm until they reach the Sphere.

Realms featured in the series
- Storm Realm: The Storm Realm is a Racing Realm with tracks that loop and curve around the sides of clouds, as if they were clinging to colossal mountainsides. The Storm Realm is an electrically charged world of flickering lightning and booming thunder. This realm tests a driver's ability to focus and avoid distraction.
- Swamp Realm: The Swamp Realm features a winding track that curves through and around gigantic jungle trees growing from a fetid swamp below. Giant worms, giant mosquitoes, and hungry creatures lurk in the shadows and are ready to take out the drivers. The track itself is alive and continuously growing, forcing drivers to constantly choose the best terrain at any given moment.
- Cavern Realm: The dark and daunting Cavern Realm features sudden turns and stops, unexpected drops and dips, and sections of track that veer into total darkness as well as falling boulders and giant bats. The Accelerons designed the Cavern Realm to test a driver's ability to drive in the dark while avoiding obstacles. As such, stalactites and stalagmites appear throughout the course.
- Lava Realm: Huge flaming boulders, lava eruptions and magma geysers are just some of the dangers that drivers face in the Lava Realm. With flowing lava a constant threat, drivers will need to master tire dexterity if they hope to stay off the sidelines and stay alive.
- Water Realm: The track in the Water Realm runs above, on, and below the surface of the ocean. Sections of track that are completely submerged run through translucent tubes. Periods of breaks prevent flooding, but allow cars, sea creatures, and some water to pass through. Ravenous sea creatures wait for unsuspecting drivers in the darkness. The Water Realm will test a driver's ability to avoid hydroplaning and spinning out.
- Metro Realm: The Metro Realm offers a vast night-time cityscape to explore, eerily deserted and dotted with neon signage and streetlights. The interconnecting streets of this bizarre metropolis will force a driver to master the skills of braking, cornering and driving through traffic. To help complete this realm a driver must remember balance increases traction.
- Cliffside Realm: Drivers will need to navigate hairpin turns while avoiding rockslides, falling rocks and large flying vultures if they hope to make it to the end of the Cliffside Realm. Mastering the art of drifting (which means taking tight turns while minimizing loss of speed) will be essential.
- Ice Realm: With a track made of ice that can crack and collapse at any moment, the Ice Realm presents a chilling challenge for any driver with it being on a glacier. Competitors will need to be good at negotiating slick surfaces if they want to make it to the finish line.
- Neon Pipeline Realm: The Neon Pipeline Realm is a unique Racing Realm that features a track running inside and around the outside of a huge pipeline. Drivers will have to race at all angles (and even upside-down) on their way to a win. Mastering drafting will take them one step closer to success.
- Junk Realm: The Junk Realm is a Racing Realm that will take drivers through a junkyard filled with scrap metal and rusty old cars. Piles of junk fall down on the track, threatening to crush drivers underneath. There's also problems with piles of debris on the road, electromagnetic lifters, compactors, wrecking balls, and a big metal fire-breathing dinosaur. The Accelerons designed this realm to test a driver's ability to hit the apex of a turn.
- Ruins Realm: The Ruins Realm is a Racing Realm with an atmosphere that evokes Tikal, Easter Island and Stonehenge. The Ruins Realm is peppered with colossal statues and stone buildings. With an ancient marble track that threatens to collapse at any time, 4-headed stone creature, and collapsing pillars, drivers must hone their skills if they want to win.
- Cosmic Realm: The Cosmic Realm is a Racing Realm that features a track composed of colorful planetary rings that lie suspended in space. Meteor showers and a neighboring black hole are just a few of the hazards that this realm contains. This realm is designed to test a driver's skill in high-speed control since the low-gravity environment requires the driver to produce as much down force as possible in order to avoid floating off the track.
- The Wheel of Power's realm symbols are different from the ones in World Race.
- The Racing Drones completed the Warped, Fog, and Monument Realms by the time of Ignition.
- There are 4 Realm symbols shown on the Wheel of Power that aren’t shown in the movies or card game. It is unknown if they are undiscovered, or have been discovered already, off-screen.
