<p>An energy-saving vehicle (1), comprising a housing, a pair of front wheels and a pair of rear wheels driven by a power unit, and a steering wheel, wherein the housing comprising an outer portion (2), an inner portion (3), an air-flow channel (4) disposed between the outer portion (2) and the inner portion (3), at least a first air inlet (7) disposed in the front of the vehicle, and at least an air outlet (8) disposed at the back of the vehicle, the first air inlet (7) and the air outlet (8) are connected to the air-flow channel (4), and a length of the air-flow channel (4) is no less than that of an upper portion of the housing. As the vehicle (1) travels at a high velocity, air is led in from the air inlet (7) and sprayed from the back of the vehicle (1), instantly filling a low pressure region (713) at the back of the vehicle and turning the back of the vehicle into a high pressure region, which saves energy. Moreover, since the length of the air-flow channel (4) is larger than that of the upper portion of the housing, lift resistance is eliminated, and the vehicle (1) travels more stably.</p> |
