The invention discloses an automobile doorsill with high safety performance, which comprises an inner doorsill, an outer doorsill and a doorsill reinforcing assembly arranged in a mounting cavity formed between the inner doorsill and the outer doorsill, and the doorsill reinforcing assembly comprises a main reinforcing assembly and an auxiliary reinforcing assembly which are matched with each other; the main reinforcing assembly comprises a plurality of supports connected to the inner side of the outer doorsill and main reinforcing beams connected to the supports and arranged in the length direction of the outer doorsill. Through mutual cooperation of multiple energy absorption structures and the counteracting effect of impact force generated by the first arc-shaped crushing plate, the second arc-shaped crushing plate, the crushing inner pipe and the crushing outer pipe, collision energy can be fully absorbed, the impact force to the interior of an automobile during collision is reduced, the side collision resistance of the automobile is greatly improved, and the safety of the automobile is improved.
