The embodiment of the invention provides an integrated electric drive axle and an automobile, and relates to the field of automobiles. The integrated electric drive axle comprises a driving wheel, a first intermediate shaft, a second intermediate shaft and a differential mechanism. The first intermediate shaft comprises a first shaft body, a first driven gear, a first driving gear and a second driving gear, the first driven gear, the first driving gear and the second driving gear are all fixed to the first shaft body, and the first driven gear is in meshing transmission with the driving wheel; the second intermediate shaft comprises a second shaft body, a second driven gear, a third driving gear and a fourth driving gear, the second driven gear, the third driving gear and the fourth driving gear are all fixed on the second shaft body, and the second driven gear is in meshing transmission with the driving wheel; the first driving gear and the third driving gear are in meshing transmission with the differential mechanism, or the second driving gear and the fourth driving gear are in meshing transmission with the differential mechanism. According to the integrated electric drive axle, the transmission efficiency can be improved, power transmission is stable, and the service life of the gear and the bearing is guaranteed.
