Bowser vs. DK Tour

The Bowser vs. DK Tour is the forty-third tour of Mario Kart Tour, which began on May 5, 2021, and will end on May 18, 2021. This tour is the third to feature a Team Rally event, pitting Team Bowser against Team Donkey Kong. This is the first tour in the game that did not introduce any new drivers. It is also the first tour since the Jungle Tour to not introduce any course variants or new courses, and the second tour after the Snow Tour to have two special pipes. This tour's Coin Rush course is DS Airship Fortress, which was reused from the Pirate Tour. The menu's background features the airships from Airship Fortress as the landmark for this tour, which was also reused from the Pirate Tour.

A fifth set of Expert Challenges was made available at the start of this tour.

Starting from this tour, Penguin Luigi, Dixie Kong, and Nabbit are now available in regular tour pipes, including the All-Clear Pipe.
