In Showdown Race Events, the player competes in a basic three lap race that adhere to the basic rules and gameplay mechanics of a Team Race in Team Sonic Racing. As such, the player competes as a single playable character with two teammates to race with and rival teams to race against. Four teams of three competes in this Event (including the player's team), for a total of twelve racers at a time. The teams' different standings during a race are displayed on the left side of the HUD and is constantly updated. Each distinguished team on this display also has its own color, which makes it possible to identify the characters who are backlit with these colors. Out on the race track, rival racers are highlighted in red. Racers can also pick up power-ups from the Item Boxes on the race tracks and use them against rival racers. The racers can also pull off various team maneuvers, such as the Item Box Transfer, Slingshot, Skim Boost, Rival Takedown and Team Ultimate.
In Showdown Race Events, the player's goal is to face Team Eggman and their two ally teams in a three-lap Team Race. The opposing teams the player will be facing are typically composed of Eggpawns. Depending on the stage in Team Adventure however, Team Eggman's team may have different members, such as Zavok, Metal Sonic and Dr. Eggman. In other races though, their spots on the team are taken by Eggpawns or the Death Egg. Regardless, the Eggpawns on the opposing teams can
be destroyed by the player in a small explosion by ramming into them or by hitting them with an offensive Wisp power-up. After an Eggpawn is destroyed however, a new one will appear to take its place.
A Showdown Race Event will conclude once all the racers have made three laps around the race track. However, when deciding the winning team, the racers on each team all contribute individually to the team's final place in the race, meaning crossing the finish line first will not always be enough. Instead, the team gets points based on their members' final positions in the race. The better the members' final positions in the race are, the more points the player's team will receive. When reaching the result screen, points will be assigned for each racer's final position (15 for first place, 12 for second, then 10, 9, 8 and so on), and totaled up for each team. The team with the highest total score are declared the winners of the Showdown Race.
