A powertrain comprises a planetary gearing arrangement that includes two sun gear members, two ring gear members, a single carrier member, and an interconnecting member that connects either the two sun gear members or the two ring gear members. The powertrain includes an input member and an output member, one of which is connectable to the carrier member and the other of which is connectable to the first ring gear member. A first electric machine and a second electric machine are included in the powertrain. The second electric machine is operatively connected to the first sun gear member to drive the first sun gear member, and the first electric machine is operatively connected to drive that one of the second ring gear member and the second sun gear member which is not connected to the interconnecting member. A brake is selectively engageable to hold the input member stationary.
