Royale is one of Peach's karts in Mario Kart DS, the others being the Standard PC and the Light Tripper. It resembles a Bugatti Royale in both appearance and namesake. A few staff ghosts use this kart as well.
Peach's Royale has fairly low top speed and handling, but above-average acceleration and extremely high drift. Being Peach's large kart in this game, it has a maxed out items stat and is much heavier than her other karts; in fact, it is the 4th heaviest kart in the game by base weight.
Due to its max items stat and exceptionally sharp drifting, the Royale is a great choice for courses with very sharp turns, such as Baby Park. However, it performs much worse on courses where tight turning is not needed. Its high drift also completely prevents it from snaking.
