1. A multi-speed electric axle comprising:
an electric motor rotationally coupled to an input shaft;
a planetary gearset connected to the input shaft via an input gear reduction;
a lower-speed clutch configured to selectively ground a gear in the planetary gearset;
a higher-speed clutch configured to selectively connect a sun gear to a case of a differential;
a housing enclosing the planetary gearset, the higher-speed clutch, and the lower-speed clutch; and
a first actuation assembly configured to actuate the higher-speed clutch and positioned axially between a carrier in the planetary gearset and a first plate carrier that is included in the higher-speed clutch;
wherein the first plate carrier is coupled directly to the case.
