Summer Tour (2023)

The Summer Tour is the hundred-and-third tour of Mario Kart Tour, which begins on August 23, 2023 and ends on September 6, 2023. This tour introduces a new city course based on Madrid, called Madrid Drive. With this tour's introduction, there has been a tour named after each season during the game's fourth year, as there were also tours named after seasons for Autumn, Winter, and Spring.

The tour also introduces a purple variant of the Pit Crew Toad, and a new outfit for Mario based on his black and blue suit from Super Mario Odyssey. Additionally, many sport-themed vehicle parts are introduced in this tour, relating to baseball and golf.

This tour concludes the Summertime Celebration which occurred in the two previous tours.

This tour features the first appearance of any Los Angeles Laps route since the 2022 Autumn Tour, the first appearance of any Tokyo Blur route since the 2023 Winter Tour, and the first appearance of any Berlin Byways route since the Spring Tour. This tour also marks the first reappearance of Wii Moonview Highway following its debut in the Night Tour. This is the also first tour since the Anniversary Tour to introduce Mario in any costume.
