1. A powertrain system, comprising:
an output;
a first electric motor with an uninterrupted connection to the output;
a second electric motor with an interruptible connection to the output;
wherein the first and second electric motors are different types;
wherein the first electric motor is located upstream relative to the second electric motor;
a first gear train coupled to the first electric motor at an end opposite the output;
wherein the first gear train includes a first planetary gear;
wherein the first planetary gear includes a sun gear, a ring gear surrounding the sun gear, and one or more planet gears engaged between the sun gear and the ring gear;
wherein the sun gear is attached to the first electric motor;
a selectable one-way clutch (SOWC) including a clutch engagement member and an actuator configured to selectively engage and disengage the clutch engagement member with the ring gear;
a first output shaft connecting the first planetary gears to the output;
a second gear train coupled to the second electric motor;
wherein the second gear train includes a second planetary gear and a clutch configured to engage the first output shaft; and
wherein the first electric motor and the second electric motor are sandwiched between the first gear train and the second gear train.
