Mario vs. Luigi Tour (2023)

The Mario vs. Luigi Tour will be the ninety-eighth tour of Mario Kart Tour, which will begin on June 14, 2023 and end on June 27, 2023, as indicated by a banner located internally in the game's files. This tour pitted Team Mario and Team Luigi against each other for the third time, making this the third instance of two teams from a previous Team Rally going against each other again after the second Mario vs. Luigi Tour and the second Peach vs. Bowser Tour, and the second rematch between Team Mario and Team Luigi.

This will be the last tour to feature the thirteenth set of Expert Challenges, which started in the 2023 Yoshi Tour.
