A two-speed gearbox assembly includes a housing, a first planetary gear set configured to operably connect to an output of an electric motor, a second planetary gear set rotationally coupled to an output of the first planetary gear set, and a third gear set rotationally coupled to an output of the second planetary gearset. A first clutch is configured to selectively couple the first planetary gear set to the second planetary gear set, and a second clutch is configured to selectively ground a portion of the second planetary gear set to the housing. The gearbox assembly is selectively switchable between (i) an on-road first gear where the first clutch is engaged and the second clutch is disengaged, and (ii) an off-road second gear where the first clutch is disengaged and the second clutch is engaged to provide sustained high torque and low speed.
