A radio-controlled toy vehicle is provided with four non-steerable wheels, two on each lateral side of the vehicle. In one embodiment, the wheels on each lateral side are drivingly coupled with a separate, reversible motor. The vehicle is steered by controlling the operation and direction of each motor. In another embodiment, the wheels on each lateral side are drivingly coupled with a single reversible motor. The vehicle is steered through one-way clutches which allow the wheels on one lateral side to operate in either a forward or a reverse direction while the wheels on an opposite lateral side always rotate in the same direction. In both embodiments, a pivoting beam is centrally located on one lateral side, with the wheels on that side being rotatably attached to the beam. The pivoting beam provides for infinite ranges of suspension positions. In operation, the vehicle proceeds until it encounters an obstacle. Depending upon the size of the obstacle relative to the size of the vehicle wheels, the vehicle either rolls over the obstacle or climbs up the obstacle and flips over. In yet another embodiment, two beams are provided, each supporting a pair of front and rear wheels on separate lateral sides of the vehicle.
