1. An assembly, comprising:
a transmission at least partially enclosed in a housing, the transmission comprising a planetary gear set coupled to a multispeed sub-transmission, the planetary gear set configured to be coupled to a first electric machine and an internal combustion engine on a first side, and configured to be coupled to a second electric machine on a second side, the first side and the second side defined by a vertical plane that is perpendicular to a central axis of rotation of the planetary gear set, wherein the first electric machine, the second electric machine, and the internal combustion engine are arranged outside of the housing, and further comprising a battery configured to be coupled to the first electric machine and the second electric machine, the internal combustion engine coupled to the transmission via a different input shaft than each of the first electric machine and the second electric machine, wherein the internal combustion engine, the first electric machine, and the second electric machine are each positioned on a same side of the vertical plane.
