The present invention relates to a toy vehicle provided with an energy storage mechanism for propelling the vehicle. The vehicle is provided with a frame, an axle having wheels secured thereto, the axle being mounted for rotation with respect to the frame, an energy source consisting of a housing provided with a gear, a spring having one end attached to the housing and coiled within the cavity, and a second gear provided with a stem positioned within the cavity and to which the other end of the spring is attached, a gearing mechanism that is activated by the rotation of the axle in one direction to rotate the first and second gears in opposite directions to store energy in the spring by coiling same, the release of the axle thereafter releasing the stored energy causing the axle to rotate in the opposite direction to propel the vehicle. The gearing mechanism includes a ratchet for preventing the first gear from rotating after the axle is released as the vehicle is being propelled, and moveable gearing mechanisms for disengaging the aforesaid driving connections after release of the axle.
