Mario Kart 8

Mario Kart 8 is an upcoming Mario Kart game for the Wii U, releasing in Japan on May 29, 2014, North America and Europe on May 30, 2014, and Australia on May 31, 2014. The game is the eighth installment in the mainstream series, and eleventh overall in the Mario Kart series. Anti-gravity, a new feature for the Mario Kart series, has been confirmed. Bikes, gliders, and underwater driving are also confirmed to return. Buggies have been confirmed to join traditional karts and bikes as a new class of vehicle.

Gameplay
The gameplay maintains the traditional elements of previous Mario Kart games, mostly from the two recent installments on Wii and 3DS respectively. Karts, which feature similar designs from Mario Kart 7, can be customized once again, alongside the returning bikes, which handle similar to the karts now and can only perform a wheelie via a boost, and the newly introduced buggies, as well as, according to an interview, more customization options that have yet to be revealed. . The hang-glider and underwater mechanics also return, as well as Coins and as in Mario Kart 7 the player can collect up to ten coins at one race. Like in Mario Kart Wii, twelve racers are present in normal races.

The newest feature for the series is anti-gravitional segments, that not only allow for more dynamic track design, but allow racers to drive across the side of a track and upside-down as well. When in anti-gravity, if a racer bumps into another racer the kart spins rather than just bumping and the racers receive a speed boost. These tracks have been described as more narrow when compared to previous Mario Kart tracks, specifically those from Mario Kart Wii. For the fourth time in the series, courses from previous Mario Kart games will be included, and both the game's anti-gravity mechanic, as well as Mario Kart 7 's "air, land, and sea" mechanic will be incorporated into these retro courses, much like the retro courses in Mario Kart 7.

It has been confirmed that there will be Miiverse integration, which will allow players to share their replay videos and comment on others' videos, in a feature called "Mario Kart TV". Another change is that in 2-player mode, the screen will split vertically instead of the horizontally in the other console Mario Kart games, a feature that was originally intended to be in Mario Kart 64 but was removed from the final game.

Development
Development for Mario Kart 8 started in 2012. Some ideas that were scrapped in Mario Kart 8 included a drill that made drivers drive into subterranean depths. The idea was scrapped because the developers thought it was not as interesting as the anti-gravity idea. The anti-gravity concept stemmed from the Wii U being a powerful console, and with the upgraded hardware, the developers wanted to make courses with a 3D plane in mind rather than the 2D plane as the other tracks in the Mario Kart series.

The title, Mario Kart 8, is chosen to represent the anti-gravity mechanic as the "8" used in the official logo resembles the Möbius strip from Mario Circuit.

Limited Edition
A limited edition version of Mario Kart 8 is available to pre-orders in the European and Australian regions. It includes the game as well as a Spiny Shell figurine.

Collaboration with Pennzoil
Nintendo and Pennzoil teamed up to promote Mario Kart 8. It features real-life go-karts on a specially modified track. Icons representing some of the items in the game are spread in the course as well.

Card Game
Nintendo is also developing a Mario Kart-themed card game. The game features two types of cards: Mario cards (includes Peach and Luigi cards) and Rosalina Cards (includes Lakitu and Koopalings cards). These cards come with the Japanese version of the game.
