The special modes of each race consist of the "Relic Race", the "CNK Challenge", the "Crystal Arena" and the "Gem Cups". In the Relic Race, the player must race through a track alone and complete three laps in the fastest time possible. To aid the player, "Time Crates" are spread throughout the track. When the player drives the character through a Time Crate, the clock freezes for whatever number of seconds are indicated on the Crate. If all of the Time Crates on a track are destroyed, the player's final time will be reduced by ten seconds. The player wins a Relic by beating the time indicated on the screen. The CNK Challenge is played like a normal race, except that the player must also collect the letters C, N and K scattered throughout the track. If the player manages to collect all three letters and come in first place, a "CNK Token" is awarded. These tokens come in four different colors. If the player collects four tokens of the same color, the player will be able to access the Gem Cup of the corresponding color. Gem Cups are racing tournaments held against computer-controlled opponents, and are accessible through a special gate at Velo's Coliseum. If one of these cups is won, a Gem is awarded. When the player collects all the Trophies, World Keys and Relics, the player will be able to race against Emperor Velo on his personal racing track. If the player manages to defeat Velo in this race, the game is won.
