Sunshine Tour

The Sunshine Tour is the one-hundred-and-first tour of Mario Kart Tour, which begins on July 26, 2023 and ends on August 8, 2023. This tour introduces Lakeside Park from Mario Kart: Super Circuit as a brand new classic course to the game while also adding in R/T variants for GCN Daisy Cruiser and SNES Koopa Troopa Beach 2; the latter’s R/T variant was previously seen in a screenshot during the Summer Tour. As of this tour, all Yoshi colors from Mario Kart 8 are present in Mario Kart Tour.

This tour marks the first reappearance of Sydney Sprint since the 2nd Anniversary Tour, the first reappearance of GCN Daisy Cruiser since the 2022 Mario vs. Luigi Tour, the first reappearance of Wii Daisy Circuit since its debut in the Princess Tour, and the first reappearance of SNES Koopa Troopa Beach 2 since the Samurai Tour thirty-five tours prior.

The Summertime Celebration begins this tour. It is unknown how many tours this celebration will last for.

The YouTube videos linked to the in-game news announcement for the tour trailer and Mii Racing Suit trailer were initially marked as private rather than unlisted and were publicized on the platform later than usual. The tour's trailer, however, was still publicly viewable on Twitter.
