The invention discloses an eight speed gearbox and a vehicle with the same. The eight speed gearbox comprises double clutches which comprise a first clutch and a second clutch, a first input shaft and a second input shaft, wherein the first input shaft is connected with the first clutch, a plurality of drive gears are fixed on the first input shaft, each drive gear is provided with an odd number of gear positions, the second input shaft is connected with the second clutch, a plurality of other drive gears are fixed on the second input shaft, each drive gear of the second input shaft is provided with an even number of gear positions, a plurality of driven gears which are respectively provided with odd numbers of gear positions and a plurality of driven gears which are respectively provided with even numbers of gear positions sleeve each of the first output shaft and the second output shaft, and a first reverse drive gear and a second reverse drive gear are respectively fixed on two sides of each driven gear. The eight speed gearbox further comprises a reverse gear shaft, and a plurality of synchronizers which are used in combination with the corresponding driven gears and the corresponding output shafts or the reverse gear shaft, wherein a first reverse driven gear and a second reverse driven gear sleeve the reverse gear shaft in suspension mode. The eight speed gearbox can reduce the number of the drive gears, and thereby decreases the self size, and simultaneously, the eight speed gearbox is provided with two reverse gear modes.
