The Ultimate Meter is a simple, slightly curved energy bar that appears behind the rear of the playable characters' racecars during a race. The meter itself is gray, while its energy bar is white.
In the gameplay of Team Sonic Racing, the Ultimate Meter is a mechanic available to all racing characters in the game. When starting a race, each character's Ultimate Meter will be empty. When a character's Ultimate Meter is full however, their character icon on the HUD will turn from blue to yellow.
By pressing // while the Ultimate Meter is full, the player can initiate the Team Ultimate, which grants their playable character an unstoppable speed boost. The duration and effectiveness of the boost will be increased if all three team members activate the Team Ultimate at the same time. In addition, When the player activates the Team Ultimate, AI-controlled teammates will also activate them at the same time. While using the Team Ultimate however, the Ultimate Meter will slowly decrease; once it empties, the Team Ultimate ends.
In order to fill up the Ultimate Meter, the player has to execute the following team actions:
- Skim Boost: Skim past a teammate to give them a speed boost.
- Slingshot: Stay in a teammate's trail to charge a speed boost.
- Item Box Transfer: Exchange Item Boxes with your teammates.
- Rival Takedown: Take out a Rival with Wisps or shunts.
Also worth noting is that whenever one of the player's two teammates, whom the player will be racing alongside with during each race, performs a Ultimate Meter-charging team action, the player's Ultimate Meter will be filled up as well and vice versa.
