The invention provides a vehicle with a vehicle tail capable of protruding backwards. The tail of the vehicle is provided with a driving device and an expandable cabin, the vehicle tail has a protruding state and a non-protruding state, when the vehicle protrudes, the driving device drives the vehicle, the vehicle tail protrudes backwards, and the cross sectional area of the protruding part is gradually reduced towards the rear of the vehicle; therefore, a tail airflow negative pressure area formed when the vehicle runs can be reduced, and the wind resistance of the vehicle is reduced; when the vehicle runs at a high speed, the vehicle tail protrudes to reduce the wind resistance of the vehicle. For an electric automobile, overlarge wind resistance affects the endurance of the automobile, great reduction of the wind resistance is of great significance for the automobile, energy consumption reduction is one aspect, and more significance is that the endurance of a pure electric MPV model meets the requirements of people, the charging frequency can be reduced, the construction pressure of a charging system is reduced, the time of people is saved, and the economic operation efficiency is improved.
本公开提供了一种车尾可向后突出的车辆,所述车辆尾部有驱动装置、可拓展舱,车尾有突出和不突出两种状态,突出时驱动装置驱动,车尾向后突出,突出的部分往车后方向其横截面积逐渐缩小,有利于减小车辆行驶时形成的尾部气流负压区,减小车辆风阻;在车辆高速行驶时车尾突出,用于减小车辆风阻。对于电动汽车,过大的风阻影响了车辆续航,大幅降低风阻对此类车辆很有意义,能耗降低是一方面,更有意义的是,例如使纯电MPV车型的续航满足人们要求,可以减少充电频率,降低充电系统建设压力,节约人们时间,提高了经济运行效率。
