The Standard LG is the same style as Mario's Standard MR, but is colored green, has different stats and the emblem is Luigi's signature green "L", unless the player has their own personal emblem enabled.
During races, the CPU controlled Luigi may pick this kart to race with more frequently than his other karts.
As mentioned above, the Standard LG has different stats from Mario's Standard LG. It has improved speed, acceleration and handling, but has weaker drift. In terms of hidden stats, it has improved off-road and Mini-Turbo. However most of its stats are weaker than Luigi's Poltergust 4000.
Its speed is shared with Waluigi's Standard WL, its acceleration is equivalent to Mario's Shooting Star, its weight stat is equivalent to Mario's Standard MR, Donkey Kong's Wildlife and Waluigi's Gold Mantis. It shares its items stat is shared with all other characters' Standard Karts.
Also, just like with all other characters' Standard Karts, Luigi's Standard LG has different stats in Battle Mode.
