Gallery:Sponsors in the Mario Kart series

During the various Mario Kart races held by Mario and his fellow racers, sponsors can be seen.

Mario Kart 64
The Japanese version of Mario Kart 64 features several sponsors whose names and logos are puns on real companies, all of whom at the time of release were major on-track advertisers at Formula 1 auto races. These sponsors are "Luigip" (pun on Agip), "Marioro" (Marlboro), and "Yoshi 1" (Mobil 1). Also, the Japanese version of the "Koopa Air" logo has the color scheme of Goodyear's. These were taken out in the English version, presumably to prevent lawsuits of the companies (and tobacco references in the case of "Marioro").

The "Shot!" logo, even in the American version, seems to bear some resemblance to that of Shell, largely due to the similarity of the names (it can also be considered a pun that the logo is a Koopa shell, though Shell's logo is a stylized seashell).

Mario Kart DS
The "Mario Star" logo also appears on the banner above the finish line of the Mario Circuit stage in Super Smash Bros. Brawl, now reading "Mario Circuit" instead of "Mario Kart".
