The invention discloses an automobile energy absorption box. The automobile energy absorption box comprises an energy absorption box body; the section of the energy absorption box body is quadrilateral; a plurality of grooves are formed in the surface of the energy absorption box body; all the grooves are formed in the radial direction of the energy absorption box body; through holes are formed inthe positions, located in the grooves, of the energy absorption box body; a first connecting plate is arranged at one end of the energy absorption box body, and a second connecting plate is arrangedat the other end of the energy absorption box body; and reinforcing plates are arranged at the joint of the first connecting plate and the energy absorption box body and the joint of the second connecting plate and the energy absorption box body. According to the energy absorption box, the specific energy absorption rate of unit mass is very high, collision at low and medium collision speeds can be well coped with, and the maintenance and replacement cost is very low.
