Rainbow Road (Mario Kart 8)

Rainbow Road is the fourth and final course of the Special Cup in Mario Kart 8. Different from its predecessors, this incarnation takes place in a space station, with Mario Kart TV satellites floating, satellite-formed bleachers with audience cheering, andthe road itself has given a new, reflective look. It is located above the Earth's atmosphere, similar to that of Rainbow Road from Mario Kart Wii. One noticeable feature of the track is a space shuttle that resembles a Blooper, that circles around the track, similar to how the train circles around the Lightning Cup's N64 Rainbow Road. The track, similar to Rainbow Road in Super Mario Kart, is made of color square tiles but it change colors like the Rainbow Roads from Mario Kart Wii and Mario Kart 7. The rainbow colors are a similar pattern from the Mario Kart: Double Dash!! version, which is mainly consist of light pink.

Unlike all previous renditions, this one is technology-themed and has a vast futuristic design which appears more like a stadium floating in the atmosphere. The game's producer, Hideki Konno, describes it as "spectacular."

Course layout
The course starts with the rainbow-colored tiles. After a turn the drivers find the first anti-gravity section, that is 8-shaped. A gliding pad is found after the anti-gravity section and leads to the central space station. It contains conveyor belts with opposite directions that changes each lap, like Toad's Factory from Mario Kart Wii. At the end of the conveyor belts there is a slope with alternate Boosts (that turn on and off through time) and at the end of it are two gliding pads. Afterwards, the drivers are launched up through three Launch Stars that lead to two different anti-gravity paths, which are twisting and inclined downwards.

These paths alter in height, so if the player falls from the highest one, they can simply land on the other one. The lower path offers drivers a shortcut if they stay to the right of the spin boost obstacle and go off the edge. The player can see a Blooper-like spaceship orbiting around. Then the paths reunite each other and the antigravity section ends. A 180° turn with some Boosts Pad at the outermost part, like in Mario Kart Stadium, and another turn make the track loop end. At the final 180° turn the player can see a hologram projection of the Special Cup Trophy as it appears in Mario Kart 8, but only in single-player mode. The racers then start the next lap.
