Abstract: A vehicle traction-increasing apparatus for creating subambient pressure beneath the vehicle to place a load on the vehicle and increase the traction between the driving wheels of the vehicle and the road surface. The air induction system of the vehicle driving engine is connected to a housing located beneath the vehicle. The bottom portion of the housing is open and applied to the road surface. A flexible curtain is connected to the housing about its open side and is urged downwardly toward the road surface. The resiliency and configuration of the curtain is sufficient to allow only a small opening between the road surface and bottom edge of the curtain so that a significant pressure reduction must be created to flex the curtain, yet once the curtain is flexed away from the road surface, it forms a virtually friction-free bearing with the road surface and is movable across the road surface without appreciable drag.
