The Tempest's design is mostly based on AMC General's Hummer H1, sporting a yellow paint job two small headlights and thick rubber wheels. It also has a rack behind the cyan-colored driving seat.
In gameplay, the Tempest possesses medium speed, acceleration, and handling. Knuckles' Tempest also stands out from other racing vehicles in that it lets Knuckles use two special abilities. The first ability is to "Punch" any nearby racers, which causes them to drop a Ring they have collected and spin out temporarily. If Knuckles does not have anyone racing next to him, the Tempest will perform a flying "Jump" similar to the one used by Tails and his Whirlwind S7. Using this ability however, costs two Rings.
|Knuckles the Echidna||Tempest||Knuckles can Punch opponents (if one is near him), causing them to lose a Ring and spin out, or Jump over them, like Tails or when using Jump. The Jump is also good for avoiding obstacles such as Mine.||Medium||Medium||Medium|
