The invention relates to an electric car. The electric car comprises a chassis, a whole car shell and more than three rolling mechanisms, wherein the chassis is arranged on the whole car shell and comprises a plurality of tracks in different directions, which are in one-to-one correspondence with the rolling mechanisms; the rolling mechanisms are arranged in the tracks; each track adopts a telescopic structure and can extend out of the chassis. The electric car dispenses with not only a production environment compatible with a conventional electric car or automobile production line but also an additional power-driven mechanism, realizes simultaneous changes of the wheel track and the wheel base, allows the gravity center of the whole car to be adjusted, and can not only be parked and charged indoors but also run on roads.
