Stunt Race FX is a racing game with various anthropomorphic vehicles. The player can choose between three vehicles (F-Type is like a Formula One, COUPE is a coupé, and 4WD is a monster truck), a fourth unlockable (2WD), or a fifth in bonus games (TRAILER which is a semi-trailer truck). The eyes as headlights was a late-in-development addition. Each vehicle has different capabilities of speed, body, and acceleration. According to the instruction booklets in English, the vehicles are male, but in the Japanese instruction manual and the Japanese television commercial, the COUPE is female and every other vehicle is male. The game features five modes: three for racing levels, one for obstacle courses, one for test-driving, one for time-attacking, and one for multiplayer racing. During gameplay, vehicles can use various functions to their advantage; the speed can be boosted, L and R buttons make sharper turns, and vehicles are damaged by collisions. The capabilities of the Super FX chip are demonstrated extensively. Each course is constructed of 3D polygons, complete with road bumps, overhead passes, and detailed billboard advertisements. The lack of speed is incorporated into gameplay by featuring cars that are heavier and clumsier than in conventional racing games.
