Narrow-track vehicle

A narrow-track vehicle is a vehicle that leaves a narrow ground track as it moves forward. Narrow-track vehicles may have lateral stability when stationary but usually lean into turns to prevent falling towards the outside.[1][2]

Narrow-track vehicles have unique dynamics that, in the case of wheeled vehicles, may be similar to bicycle and motorcycle dynamics and that may include countersteering.[3] Narrow-track vehicles can roll on wheels, slide, float, or hydroplane. The narrow profile can result in reduced aerodynamic drag, increased fuel efficiency, and reduced pavement requirements.[4][5] These types of vehicles have also been described as "man-wide vehicles" (MWV).[4]
