The invention discloses a multi-gear hybrid power transmission and an automobile. The multi-gear hybrid power transmission comprises an engine (110), a clutch (120), a first motor (130), a second motor (140), a planetary gear mechanism (150), a first input shaft (160), a second input shaft (170), an output shaft (180), a brake (190), a synchronizer (210), a first gear pair (220) and a second gear pair (230), wherein the first gear pair (220) and the second gear pair (230) are different in speed ratio. The flywheel output end of the engine (110) is connected with the first input shaft (160), a rotor of the first motor (130) is in transmission connection with the gear ring (154), the brake (190) is connected with the sun gear (151), and the second input shaft (170) is arranged outside the first input shaft (160) in a sleeving mode and connected with the planet carrier (153). A first driving gear (221) in the first gear pair (220) and a motor shaft of the second motor (140) are coaxially arranged, and a second driving gear (231) in the second gear pair (230) and the second input shaft (170) are coaxially arranged; the synchronizers (210) comprise the first synchronizer (211) and the second synchronizer (212), the first synchronizer (211) is used for being selectively connected with a motor shaft of the second motor (140) and the second input shaft (170), and the second synchronizer (212) is used for being selectively connected with a first driven gear (222) in the first gear pair (220) and the output shaft (180).
