N64 Luigi Raceway

Luigi Raceway, alternatively named Luigi Circuit (which is also its Japanese name) or Luigi's Circuit, is a race course in Mario Kart 64 as the first race of the Mushroom Cup.

The music of this course is shared with Mario Raceway, Wario Stadium, and Royal Raceway in Mario Kart 64, and is used as an arrangement for the Mario Circuit stage in Super Smash Bros. Brawl. The course is reminiscent of various NASCAR-style speedway tracks with large, broad corners allowing for high-speed racing.

Luigi Raceway returns as the first course of the Shell Cup in Mario Kart 7 and also reappears in Mario Kart Tour starting with the 2022 Mario vs. Luigi Tour.

Course layout
This is the first course of the Mushroom Cup and the whole game. The course features no hazards, save for small rough terrain areas that are located all over the track. The course is long and simple, featuring open turns through which the player may employ powersliding to accelerate faster. The race begins near a grand stand full of cheering audience, atop which is a large model of the Luigi Cap. Following a long straightway and a wide banked turn to the left is a long road to a long overhang, followed by another long curve to the left and a short straightway leading back to the starting line, which happens to be part of the longest straightway in the course. During the race, a balloon depicting Luigi's head dips onto the course at the end of the first straightway, hanging an Item Box beneath. The item is always a Spiny Shell and may be obtained if a racer hops at the right time just as the balloon reaches its lowest point of descent. The course does not have any notable shortcut, but it is possible to save few seconds by cutting across the grass and sand on the turns while using a Mushroom or a Star.

Staff ghost
If a player beats the time of 1:52:00 on this course in Time Trial mode, they unlock a Luigi staff ghost.

Mario Kart 7
Luigi Raceway reappears in Mario Kart 7 as the first race of the Shell Cup. It is mostly unchanged, except the hot air balloon has been moved and a Mii character is inside the basket, and the item box hanging below it that always gave out a Spiny Shell has been replaced with a regular item box. An alternate way has also been added on the platforms next to the curves that were inaccessible in Mario Kart 64, and it has Dash Panels on them. This is one of two Luigi courses that appear in the Shell Cup, the other being from Mario Kart DS.

This course and are the only courses not to use either gliding or underwater driving features in Mario Kart 7.

Mario Kart Tour
Luigi Raceway appears in Mario Kart Tour, starting from the 2022 Mario vs. Luigi Tour. Prior to the course's introduction, two badges were released featuring the name of the track. The Luigi Parafoil also contains a Luigi Raceway logo. Luigi Raceway is the last returning track from Mario Kart 7 to return in Mario Kart Tour.

Like N64 Royal Raceway, the course uses the arrangement from Mario Kart 7 in this game, being the first non-numbered course since the introduction of 3DS Mario Circuit in the Tokyo Tour to share its music with another track.
