The invention relates to a passenger car body which comprises a car frame. A left side wall stand column, a right side wall stand column, a roof crossbeam and a chassis crossbeam of the car frame are fixedly connected on the corresponding transverse section to form a plurality of transverse closed-loop structures. A front windshield upper crossbeam, a driver window upper longitudinal beam, a passenger car door upper longitudinal beam, a side window lower longitudinal beam and a rear cabin door upper crossbeam are fixedly connected on the horizontal section of the car body to form a longitudinal closed-loop structure. The side wall stand columns are fixedly connected with the longitudinal closed-loop structure at all the joints. The transverse closed-loop structures and the longitudinal closed-loop structure are fixedly connected together to form a whole structure, the structural strength of the upper portion of the car body is greatly improved, and the whole car frame is stressed when the car turns laterally; compared with the prior art, deformation of the car body is little, more living space is provided for passengers, the probability that the passengers escape safely is increased, and the problems that when an existing passenger car turns laterally, the safety performance of the car body is low, and personal safety of passengers inside the car cannot be better protected are solved.
