Bandai Namco Games received special thanks in the credits. Nintendo's launch promotions of
Mario Kart 8 include a limited edition with a spiny shell figurine and themed console bundles, with a hat, strategy guide,
Wii Remote Plus controller, Wii Wheel, and GamePad protector. An album containing 68 tracks was made available as an exclusive reward available to Club Nintendo members shortly before the service was discontinued in 2015. Game updates added features and
user experience improvements, such as support for
Amiibo figurines, a 200cc difficulty setting, player statistics, and additional
Mii outfits. Downloadable content for

Nintendo eShop for Wii U. In March 2023, Nintendo halted online play for
Mario Kart 8 and
Splatoon due to a
security vulnerability. The problem was fixed with an update, and online play resumed on August 3. Online services for Wii U, including
Mario Kart 8 online play, were terminated on April 9, 2024.
Mario Kart 8 Deluxe .|alt=The Nintendo Switch in handheld mode. The center tablet is black, and attached on both sides are Joy-Con controllers. The left Joy-Con is blue, with several buttons. The right Joy-Con is red, with several other buttons. Nintendo
teased Mario Kart 8 Deluxe with the announcement of the Nintendo Switch in October 2016, and revealed it at the Nintendo Switch presentation on January 12, 2017. The trailer showcased mechanics such as smart steering and crossover elements from the
Splatoon series. Additional crossovers with
The Legend of Zelda: Breath of the Wild were added in an update after launch.
Deluxe was released on April 28, 2017, following the Switch's March 3 launch. An overview trailer revealed details about the battle mode including several battle mode-exclusive courses, and the return of the Shine Thief mode from
Mario Kart: Double Dash. After the release of the trailer, several
internet memes circulated surrounding
Donkey Kong appearing to perform a celebratory
dab.
Mario Kart 8 Deluxe revamps the battle mode, adds a second item slot, among other minor gameplay improvements. Shortly after launch, Nintendo released a
software update that changed one of the victory gestures done by the Inkling Girl. Prior to the update, the Inkling Girl performed a gesture that consisted of placing her hand on a flexed
bicep and pumping her fist into the air. In Japan, the gesture means something similar to "bring it on!", though in
European and
Latin American countries, it was likened to the
bras d'honneur, an offensive gesture that can be interpreted as "up your ass", "
fuck you", or similar meanings. After the update, the Inkling Girl no longer clenches her fist around her flexed arm, instead simply performing a "
fist pump", though the rest of the gesture was unchanged. A series of updates in 2018 added compatibility with
Nintendo Labo, a
toys-to-life kit that uses
cardboard to create motion-controlled toys with Joy-Con controllers. The first update enabled the Toy-Con Motorbike as a controller for
Mario Kart 8 Deluxe, allowing the player to use the physical
throttle,
handlebars, and
gyroscope present on the Toy-Con Motorbike, while actions like braking, drifting, and item pickups are still performed using the standard controller buttons. A later update added compatibility for the Toy-Con Car, Pedal, and Key to control actions like braking, drifting, and using the horn on the steering wheel to launch items. An update released on December 7, 2022, added an item customization option for certain modes, allowing players to choose which items are obtainable in a race or Battle.
Booster Course Pass During a February 2022
Nintendo Direct, it was announced that
Mario Kart 8 Deluxe would get a paid downloadable content
season pass called the "Booster Course Pass". Courses in the "Booster Course Pass" are largely remastered from their incarnations in previous
Mario Kart games. The "Booster Course Pass" was released in six waves, with each wave containing eight courses split into two cups, totaling to 48 additional tracks that were released between March 2022 and November 2023. It can be accessed by purchasing it on the Nintendo Switch's
eShop, or by having an active
Nintendo Switch Online + Expansion Pack subscription. Wave 2 was released on August 4, 2022, containing the Turnip Cup and the Propeller Cup. It also featured Sky-High Sundae, an original course not introduced in a previous
Mario Kart game. Alongside the release of Wave 2, Nintendo released an update to the Wave 1 course Wii Coconut Mall that changed the cars at the end of the course to perform
donuts, rather than remaining stationary, except for in
Time Trials. This change was widely praised, especially after many were disappointed that the cars were stationary in the "Booster Course Pass" to begin with. Wave 3 was released on December 7, 2022, containing the Rock Cup and the Moon Cup. The ability to remove certain items from "VS Race" mode and online races was also added. Wave 4 was released on March 8, 2023, in North America and March 9 elsewhere, containing the Fruit Cup and the Boomerang Cup. It also featured a brand new original course based on ''
Yoshi's Island'' (1995). Wave 5 was released on July 12, 2023, containing the Feather Cup and the Cherry Cup. It also featured a brand new course, Squeaky Clean Sprint. The final wave, Wave 6 was shown off in a Nintendo Direct on September 14, 2023, and released on November 9, 2023, containing the Acorn Cup and the Spiny Cup. Wave 6 adds a music player featuring music from all courses, and 18 additional costumes for the Mii racers. Starting in February 2023, Nintendo added eight more playable characters, all having previously appeared in other
Mario Kart games. The first of these characters,
Birdo, debuted in Wave 4;
Petey Piranha,
Wiggler, and
Kamek in Wave 5; and
Diddy Kong,
Funky Kong,
Pauline and
Peachette in Wave 6. ==Reception and legacy==
