The electrically variable transmission (14) provides low-content, low-cost electrically variable transmission mechanisms including three differential gear sets (20, 30,40), a battery (86), two electric machines (80, 82) serving interchangeably as motors or generators and five selectable torque-transfer devices (50, 52, 54, 56, 58). The selectable torque transmitting devices (50, 52, 54, 56, 58) are engaged to yield an EVT with a continuously variable range of speeds and five fixed speed ratios, including four mechanically fixed forward speed ratios and one reverse speed ratio. The torque transmitting devices (50, 52, 54, 56, 58) and the first and second motor/generators (80, 82) are operable to provide six operating modes in the electrically variable transmission, including battery reverse mode, EVT reverse mode, series reverse mode, launch modes, continuously variable transmission range mode, and fixed ratio mode.
