Electrodrome

Electrodrome is the third race course of the Star Cup in Mario Kart 8 and Mario Kart 8 Deluxe. It is set in a neon-lit filled with Koopa Troopas, Shy Guys, and Raving Piranha Plants. Banners with the Star Cup logo can be seen throughout the track, as well as some big screens displaying characters dancing, spectrum analyzers, and the MKTV logo. It is also the first (and so far only) course in the Mario Kart series to have a one-word name.

Course layout
The course starts directly in front of a Glide Ramp. After the racers glide down to the road below, there is a turn going left. Shortly after the turn, there is an anti-gravity area curving to a wall that soon splits into two roads, one pink and one green. In the area where the music changes, transparent squares of the road's color appear in the edge of the screen. The roads twist around each other before connecting. At the end of each road is a Glide Ramp leading to a large neon platform with the words "Star Cup" on it, as well as the cup’s logo. There is a small jump at the end of the platform and a left turn that leads to the finish line.

Many large screens throughout the whole course show two videos of dancing Koopa Troopas and Shy Guys, along with a silhouette of Larry as a disc jockey. During the countdown to the race, the large screen in the background shows a spectrum analyzer before switching to the dancing footage. The analyzer goes in that order during the countdown: blue, yellow, red, and rainbow. This also makes Electrodrome one of five courses with an opening animation during the countdown, with the others being Twisted Mansion, Mount Wario, Bowser's Castle, and Excitebike Arena. Stylized ? Blocks can be seen around the course below some of the giant screens.

Shortcuts

 * Players can cut off the turn before the anti-gravity section using a speed boost. This shortcut is best done with a Star.
 * At the final left turn, players can cut through the rough section with a speed boost instead of taking the turn.

Staff ghost
The staff ghost for this track is Larry on the Sport Bike, with a time of 2:24.747. In Mario Kart 8 Deluxe 200cc, the staff ghost is Roy with a time of 1:40.943.

Music
Like some courses from Mario Kart Wii and Mario Kart 7, the music has different layers depending on the location of the player. Driving on the parts of the course representing electronic instruments causes effects to be added to the music, and when racing through areas that feature a crowd of dancing Koopas and Shy Guys, hand claps become audible. This track has the most channels of music in the game, having eight different channels due to the base music, first place beats, electronic instruments, and the crowd of dancing Koopas and Shy Guys. This number of music channels is tied with other tracks, including 3DS Music Park.

Mario Kart 8 Original Soundtrack liner notes
"Unusually for the series, we used dance music here which fits the atmosphere of the shiny dancefloor featured on this track. Shy Guys and Koopa Troopas dance along to the rhythm while you're playing."

Trivia

 * In the Prima Guide for Mario Kart 8, "Electrodrome" is misspelled as "Electrodome". The book itself is not consistent, however, as starting from the Time Trials page the course's name is spelled correctly.
