The invention discloses a two-gear driving assembly and a new energy automobile. Wherein the two-gear driving assembly comprises a driving source, a speed change mechanism and a speed reduction mechanism; the speed change mechanism comprises an input shaft, a middle shaft and an output shaft which are arranged in parallel, the input shaft is in transmission connection with the driving source, a first gear is arranged on the input shaft, a second gear, a third gear and a fourth gear are arranged on the middle shaft, a fifth gear and a sixth gear are arranged on the output shaft, and the first gear and the second gear are in meshing transmission; the third gear and the fifth gear are in meshing transmission, the fourth gear and the sixth gear are in meshing transmission, the third gear and the intermediate shaft or the fifth gear and the output shaft are in transmission connection through a clutch, and the fourth gear and the intermediate shaft or the sixth gear and the output shaft are in transmission connection through a clutch. And the speed reducing mechanism sleeves the output shaft and is in transmission connection with the differential mechanism. The two-gear driving assembly has the advantages of being large in output torque, compact in structure, high in transmission efficiency, good in NVH performance, low in production cost and the like.
