In F-zero Gx and X vehcials have an E-A grading system based on stats such as Body (How much damage the machine can take), Boost (How much energy a boost uses and how powerful are the Boosts), and Grip (How the machine handels) are all factored. Yet many profesional players have found that many of the stats lie. For example the Fat Shark has an B on boost yet it has the best in the entire game. Another example of lieing stats would be the Black Bull the game says that it has an A on body yet it has an average body strength. Or the Wild Goose where the game says it has a C on grip when it has some of the worst handling in the entire game. On top of that stats like acceleration and max speed are never shown.
