The application provides a vehicle body structure and a vehicle. The vehicle body structure comprises a middle channel, a front anti-collision beam, a first longitudinal beam, a front wall cross beam assembly and a second longitudinal beam. The vehicle body structure further comprises an intermediate energy absorption structure which is located in a frame structure and connected with the front wall cross beam assembly.
