1. A vehicle comprising movable spoilers, the vehicle having at least one spoiler movable between a minimum-angle position producing a minimum increase in vertical load, and a maximum-angle position producing a maximum increase in vertical load, and spoiler actuating means for adjusting the position of the spoiler between said minimum-angle position and said maximum-angle position as a function of the speed of the vehicle, the vehicle having spoiler actuating means for adjusting, up to a given maximum speed, the position of the spoiler to increase the vertical load as speed increases, and for maintaining the vertical load at a substantially constant given value as long as the speed of the vehicle exceeds said maximum speed. 2. The vehicle as claimed in claim 1, wherein the spoiler actuating means comprise at least one electromechanical actuator for setting said spoiler, on command, to any position between the minimum-angle position and the maximum-angle position. 3. The vehicle as claimed in claim 2, wherein the spoiler actuating means comprise an electronic central control unit which controls said electromechanical actuator as a function of information acquired from other electronic central control units, sensors, or electronic central control units and sensors on said vehicle. 4. The vehicle as claimed in claim 1, further comprising at least one spoiler at the rear of the vehicle. 5. The vehicle as claimed in claim 1, further comprising at least one spoiler at the front of the vehicle. 6. The vehicle as claimed in claim 5, wherein the front spoiler is defined by two flat appendixes, each of which is hinged to a respective portion of the peripheral edge of a flat bottom of the vehicle so as to rotate flapwise at said edge. 7. The vehicle as claimed in claim 6, wherein each flat appendix is hinged to the peripheral edge of the flat bottom at a trailing end of a respective chute extractor formed on the flat bottom.
