A Mini 4WD Racer Goes Triangular—and Is Barely Four-Wheeled Anymore

A Nico Nico Douga maker named Korori built a triangular machine for the anything-goes JCJC time-attack scene. The idea targets one of the course's hardest sections, the lane change, where roller contact can slow or destabilize a conventional rectangular chassis.

By making the body triangular, the design aims to reduce that contact near the crest. In the pursuit of speed, even the familiar shape—and effectively the usual four-wheel assumptions—of a Mini 4WD car are treated as optional.
