The invention discloses an energy absorption assembly and an automobile. The energy absorption assembly comprises an anti-collision beam, a telescopic rod, an energy absorption box and a first blasting unit, wherein the energy absorption box is provided with a containing cavity, and the containing cavity is provided with a bottom wall and an opening opposite to the bottom wall; a first end of the telescopic rod is connected with the anti-collision beam, a second end of the telescopic rod is movably arranged in the containing cavity through the opening, a first sub-cavity is formed between the second end of the telescopic rod and the bottom wall, and the first sub-cavity is communicated with the external environment; the first blasting unit is arranged in the first sub-cavity, the first blasting unit is used for generating first gas, and the first gas is used for increasing the air pressure in the first sub-cavity so as to push at least part of the telescopic rod to stretch out of the containing cavity. By the adoption of the automobile energy absorption assembly, the crumple stroke of the energy absorption assembly is large, collision acceleration is small, and protection on passengers and an automobile is more ideal.
