Abstract
A transmission (G) for a motor vehicle comprising an upstream gear set (VRS), a main gear set (HRS) with a total of four shafts (W, W, W, W) referred to in order of rotational speeds as first, second, third and fourth shafts, an electric machine (EM), and at least five shift elements (A, B, C, E, F), the selective pairwise closure of which realizes at least eight selectable forward gear ratios (G-G) between a drive shaft (GW) and an output shaft (GW) of the transmission (G). The upstream gear set (VRS) provides a rotational speed at a fifth shaft (W) increased relative to the rotational speed of the drive shaft (GW), in a fixed transmission ratio with respect to the drive shaft (GW). The main gear set (HRS) is a stepped planetary gear set (PS).
