Booster Course Pass

The Mario Kart 8 Deluxe – Booster Course Pass is a DLC expansion pack for Mario Kart 8 Deluxe, announced during the February 2022 Nintendo Direct. The pack includes twelve additional cups, for a total of 48 additional courses (bringing the total number of courses in the game to 96), most of which are remastered versions of courses from other Mario Kart games, including Mario Kart Tour. The courses are based on their designs from Mario Kart Tour, but with visual improvements and new music arrangements. In addition to the courses, starting with Wave 4's release, the pass also features additional playable characters for the game, which also return from other Mario Kart games. The pass is being released through six waves, with each wave containing eight total courses (divided into two cups of four courses each). All waves are set to be released by the end of 2023. The pack marks the longest gap between the original release of a Mario game and the release of its DLC, with the first wave releasing nearly five years after Mario Kart 8 Deluxe did. The pack also makes Mario Kart 8 Deluxe the first Mario Kart game to feature classic courses from games following the original game's release, with Mario Kart Tour and its reappearing courses debuting after Mario Kart 8 Deluxe was initially released.

The Booster Course Pass can be purchased on its own, but it is also included in a Nintendo Switch Online + Expansion Pack subscription, as well as in the digital-only Mario Kart 8 Deluxe Bundle (Game + Booster Course Pass). In Hong Kong, activation codes for the Booster Course Pass are additionally distributed in physical Nintendo Switch game cases, though buyers must own a copy of the base game to be able to use a code. The first wave of the DLC was made available to pre-load on March 15, 2022, and was released on March 18, 2022. In Mainland China for the Tencent release, waves release later than they do internationally, with the pack set to completely release by the end of 2024 rather than 2023. If the player has purchased the Booster Course Pass or currently has a Nintendo Switch Online + Expansion Pack subscription, a small icon of a Super Star can be seen next to the version number on the game's title screen.

The courses shown in the key artwork use official screenshots and in-game course icons from Mario Kart Tour. Some screenshots of the courses show Paris Promenade and Paris Promenade 3 with barrier fences from that game, as well as an official screenshot of the ninja Shy Guys in Ninja Hideaway, which originated from the 2021 Ninja Tour's in-game preview. Prior to Wave 1's release, the infographic showing all of the known courses across all six waves also used Mario Kart Tour screenshots. However, in the launch trailer for Wave 1 posted following its release, the infographic was updated to use in-game screenshots from Mario Kart 8 Deluxe for all courses, which the release trailers for future waves would follow as well.

Several minor adjustments to the courses in Wave 1 were made upon the release of Wave 2, such as their course icons being slightly brighter, and the sand and dirt on some courses now leaving tire marks. Additionally, the final car section in Wii Coconut Mall was adjusted, making the cars serve as hazards and move sporadically in random directions (except for in Time Trials, in which they remain stationary as they were originally).
