This three-wheel, open-top electric autocycle explores a new kind of driving pleasure. The TRICERA proto is a working prototype using a three-wheel steering system (3WS) that delivers both stimulating cornering performance and a new steering sensation—one that makes learning to master it enjoyable in itself. Focusing on the quick cornering response and mid-corner driver connection typical of all-wheel steering vehicles, the turning control system has been tuned with a human research perspective to maximize driver fun and achieve a new level of driver–machine unity. The TRICERA proto also features our αlive AD sound control device, which tweaks and tunes the electric motor's sound to amplify the excitement and further draw the driver into the experience. Visually, the arching silhouette of the center frame emphasizes its three-wheeled structure, while the contrast between the "human space" and "functional space" gives the exterior a strikingly innovative design.
