N64 Luigi Raceway

Luigi Raceway, known in Japan as Luigi Circuit, is a race course first featured in Mario Kart 64 and reappears in Mario Kart 7. The music of this course is used as a remix for the Mario Circuit stage in Super Smash Bros. Brawl.

Mario Kart 64
This is the first course of the Mushroom Cup. 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 Luigi's green 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 doesn't have any notable shortcut, but it's possible to save few seconds by cutting across the grass and sand on the turns while using a Mushroom or a Star.

Course Ghost
If a player beats the time of 1:52:00 on this course in Time Trial mode, he or she unlocks a Luigi Staff ghost.

Instruction manual description
Long straightaways and easy corners -- the perfect course for beginners to practice their sliding.

Mario Kart 7
The track appears again in Mario Kart 7, as the first race in the Shell Cup. It is mostly unchanged, except the hot air balloon that 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 Boost Pads on them. This is one of two Luigi courses that appear in the Shell Cup, the other being DS Luigi's Mansion.

Trivia

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