A powered vehicle of the type which rides on front and rear primary road wheels that are in tandem relationship and located midway between the sides of the vehicle has a body with sides that are convergent in the downward direction enabling a high degree of leaning of the vehicle during turns. At least one auxiliary road wheel is carried at each side of the vehicle by sidewardly extending pivot arms which enable lowering of the auxiliary wheels during low speed travel and when the vehicle is stationary. At the raised position, the auxiliary road wheels extend from the sides of the vehicle in position to ride on the roadbed when the vehicle is tilted sidewardly to an inclination that is more horizontal than vertical. In the preferred form, the vehicle body has an inverted teardrop configuration in cross section and tapering front and back end regions and has an aircraft empennage at the back end. Interlinkage synchronizes raising and lowering of the auxiliary wheels and adjusts wheel camber and steering in the process. Spoiler flaps on the empennage are actuated concurrently with actuation of the vehicle braking system.

In a vehicle having a body defining an operator\s compartment and having front and rear primary road wheels disposed in tandem relationship and situated substantially midway between opposite sides of the body and further having an engine for driving at least one of said road wheels and steering means for selectively angling said front road wheel relative to said rear road wheel, the combination comprising: the lower regions of the opposite sides of said vehicle being convergent in the downward direction enabling sideward leaning of said vehicle during high speed turns, said vehicle having a configuration which enables sideward tilting of said vehicle into an orientation at which the vehicle has an inclination that is more horizontal than vertical, at least one pair of pivot arms each having an inner end pivoted to said vehicle for vertical pivoting movement about pivot axes that extend longitudinally relative to said vehicle, said pivot arms being at opposite sides of said vehicle, each of said pivot arms having an outer end that extends sidewardly relative to said vehicle, at least a pair of auxiliary road wheels each being carried by a separate one of said pivot arms at said outer end thereof, the axes of rotation of said auxiliary road wheels being substantially at right angles to said pivot axes of said pivot arms, said auxiliary road wheels and pivot arms being vertically movable between a lowered position at which said auxiliary road wheels ride on the underlying roadway and a raised position at which said auxiliary road wheels extend laterally outward at opposite sides of said vehicle in position to ride on said roadway when said vehicle reaches a predetermined degree of sideward tilting at which the inclination of the vehicle is more horizontal than vertical, further including interlinkage means for constraining said pivot arms to pivot synchronously in opposite directions and to undergo equal amounts of angular travel and wherein said interlinkage means includes an extendible and contractible hydraulic actuator and a pair of pivotable links each of which couples said actuator to a separate one of said pivot arms, and control means for enabling selective raising and lowering of said pivot arms by operation of said hydraulic actuator.
