An electric drive-unit encased in a housing includes an electric motor, a first output member, and a second output member. The drive-unit also includes first, second, and third planetary gear-sets, each having first, second, and third nodes. The first gear-set has one node connected to the electric motor. The second gear-set has one node connected to the first planetary gear-set, another node connected to the first output member, and the remaining node fixed to the housing. The third gear-set has one node connected to the first gear-set and another node connected to the second output member. The drive-unit additionally includes a first torque-transmitting device configured to selectively connect one third gear-set node to the housing to thereby affect a first speed-ratio. Furthermore, the drive-unit includes a second torque-transmitting device configured to selectively connect one first gear-set node to one of the third gear-set nodes to thereby affect a second speed-ratio.
An electric drive-unit encased in a drive-unit housing and configured to selectively provide first and second speed-ratios, the electric drive-unit comprising:
A motor vehicle comprising:
