The invention discloses a front wall assembly and a car including the same. The front wall assembly includes a front gutter channel assembly, a left A column assembly and a right A column assembly; aleft front longitudinal broadside beam, a front wall middle channel assembly and a right front longitudinal broadside beam are sequentially connected and arranged between the left A column assembly and the right A column assembly, free ends of the left front longitudinal broadside beam and the right front longitudinal broadside beam are separately connected with the left A column assembly and theright A column assembly, and the front wall assembly further includes a left front longitudinal, a right front longitudinal and a front wall plate cross beam; the left front longitudinal is connectedat the left front longitudinal broadside beam and the rear end of the left front longitudinal is connected with the left A column assembly; the right front longitudinal is connected at the right frontlongitudinal broadside beam and the rear end of the right front longitudinal is connected with the right A column assembly; and the front wall plate cross beam is arranged between the left A column assembly and the right A column assembly and is sequentially connected with the left A column assembly, the left front longitudinal, the front wall middle channel assembly, the right front longitudinaland the right A column assembly. The front wall assembly and the car including the same can reduce the invasion quantity and the accelerated speed of the front wall assembly during a collision.
