Radical Racers TCG is an American collectible card game with an automotive racing theme. Players begin each game with a set speed rating measured in miles per hour and then battle opponents by playing mutant racer character cards that adjust speed values: decreasing an opponent's rating while increasing one's own. The first player to push an opponent's speed to zero, or achieve another win condition, takes the race. The game appears on BoardGameGeek with a dedicated entry, and the mutant-racer concept suggests a stylised, exaggerated take on motorsport rather than a simulation. No publisher has been confirmed in available records, and the publication date is not documented. It is one of several small-press American racing-themed CCGs from the 2000s that circulated in limited channels and left minimal collector documentation.
