Pipe Tour

The Pipe Tour is the one-hundredth tour of Mario Kart Tour, which begins on July 12, 2023 and ends on July 25, 2023. This tour introduces a brand new pipe-themed course named Piranha Plant Pipeline, reflecting the theme of the tour. Wiggler is introduced as a new driver after its series debut in Mario Kart 7 along with a themed Mii Racing Suit, coinciding with Wiggler's inclusion in Wave 5 of the Mario Kart 8 Deluxe – Booster Course Pass (which releases on the same day as this tour). In addition, a variant of Pauline in a cowgirl outfit is introduced as a new driver, making this the first tour since the Peach vs. Daisy Tour to introduce a variant of Pauline. The tour also sees the first reappearance of Wii Dry Dry Ruins, GBA Yoshi Desert, and Piranha Plant Cove 2 after their debuts in the 2023 Ninja, Yoshi, and Exploration Tours, respectively.

Similarly to the April-May 2021 Sydney Tour, New Year's 2022 Tour, and Spring Tour, the trailer and social media announcement were publicly released later than the usual time.
