A motor vehicle drivetrain features an input shaft, an output shaft, a continuously variable transmission for coupling the input shaft to the output shaft with a variable transmission ratio between the input shaft and the output shaft, and a bypass transmission with at least one bypass gearing, which has a fixed transmission ratio, in order to couple the input shaft to the output shaft. A value of a transmission ratio of the bypass gearing is less than or equal to half the sum of a value of the maximum forward motion and a value of the minimum forward motion of the variable transmission ratio between the input shaft and the output shaft driven of the continuously variable transmission and/or less than or equal to 1.0. The bypass transmission is configured for driving the motor vehicle with a driving speed of at least 50 km/h or 31 mph.
