Mario Circuit

Mario Circuit is the name of several race courses named after Mario, the mascot of the Mario Kart Series and Nintendo itself. These courses generally have something to do with the famous plumber in them, such as banners and Peach's Castle.

Super Mario Kart
Main article: Mario Circuit 1, Mario Circuit 2, Mario Circuit 3, Mario Circuit 4

In Super Mario Kart, four different Mario Circuits appeared. These courses looked like normal racecourses, but with Pipes and Oil Slicks as obstacles.

These tracks are numbered by in the order they appear. Mario Circuit 1 is the first track of the Mushroom Cup, with few Pipes and no Oil Slicks. Mario Circuit 2, the last track of same cup, is longer and introduces Oil Slicks. It is widely known for the big jump near the end of the course. The final course of the Flower Cup, Mario Circuit 3 features a sharp turn in the middle of the course. Mario Circuit 4 is the last course of the Star Cup and is the longest Mario Circuit out of the four.

Each of these tracks, along with the rest of the course from Super Mario Kart, returned in Mario Kart: Super Circuit as hidden bonus tracks, albeit with their obstacles removed. In Mario Kart DS, Mario Circuit reappeared as a retro track, and the first track of the Shell Cup. Mario Circuit 3 returns in Mario Kart Wii in the Lightning Cup. Mario Kart 7 bears the reappearance of Mario Circuit 2.

Mario Kart 64
In the international versions of Mario Kart 64, all of the circuits were renamed raceways, so Mario Circuit outside of Japan is named Mario Raceway. Mario Raceway, the final course of the Flower Cup, is a relatively short track, standing at 567m. Piranha Plants serve as the course's obstacles.

Mario Kart: Super Circuit
Mario KartL Super Circuit's own Mario Circuit is rather plain and short in length, with few obstacles. It is the first track of the Flower Cup. It contains a hairpin turn and a 'pitstop' detour at the end of the track, with a Boost Pad and a line of coins.

All four of Super Mario Kart's Mario Circuits returned as unlockable tracks, as well.
