Bonus Boxes contain a variety of one-off upgrades that can improve your chances of victory.
— Hint box, Team Sonic Racing
The Bonus Boxes, in terms of appearance, resemble the classic Item Boxes from the early Sega Mega Drive games in the Sonic series. As such, they look like simple, gray cubic televisions with a base below them, three buttons below their screen, and a red button on their left side. Their screens themselves each depict an icon that indicate the performance enhancement they grant.
In Team Sonic Racing, the Bonus Boxes consist of a series of different types of performance modifiers, each one with its own unique modification-granting ability that is identified by the icon on their screens.
These objects can be equipped to a racer just before a race. When equipped, depending on their ability, they will either grant the player one or more Wisp power-ups from the start of the race or bestow a specific enhancement to their performance for the duration of the race, such as extending the duration of the Team Ultimate or grant immunity to Slowdowns. However, a Bonus Box is only good for one use; afterward, it disappears, leaving the player to acquire new ones. The player can purchase a Bonus Box from Mod Pods, which give out random Bonus Boxes, for ten Credits each.
