A dual-drive electric transmission operated by a generator that may be powered, for example, by an internal combustion engine. Left and right motor networks have a rotation rotor, the motor networks being powered by the generator. A speed control assembly independently effects rotation of the rotor in each motor network at selected speeds. Left and right combining differentials are associated with the respective left and right motor networks. Each combining differential has a sun gear, a ring gear and a plurality of planetary gears meshing with the sun and ring gears. An output carrier supports the planetary gears. The sun gear in each left and right combining differential is driven by the respective left and right motor network. The ring gears are conjoined for unitary rotation in order to provide a mechanical regenerative path between the combining differentials. A transfer differential interacts between the sun gears in the left and right combining differentials to serve as a mechanical regenerative path until the rotor in one of the motor networks reverse rotates under the load applied to the output carrier associated therewith, and a power transfer means thereafter effects electrical regeneration between said reversely rotating rotor and the rotor in the other motor network.
