A snowmobile includes a body extending along a longitudinal axis between a front end and a rear end, a battery pack mounted to the body and enclosing a plurality of battery modules, and an electric motor assembly mounted to the body. The electric motor assembly includes an electric motor configured to receive electrical energy from the plurality of battery modules. At least part of the electric motor assembly is positioned forwardly of the battery pack. ## Claims ### Claim 1 A snowmobile comprising: a body extending along a longitudinal axis between a front end and a rear end; a battery pack mounted to the body and enclosing a plurality of battery modules; an electric motor assembly mounted to the body, the electric motor assembly including an electric motor configured to receive electrical energy from the plurality of battery modules to drive a motor output of the electric motor; and a transmission comprising: a transmission shaft extending along a transmission shaft axis between a first end drivingly coupled to the motor output and a second end; and a drive wheel drivingly coupled to the second end of the transmission shaft, wherein an output speed at the second end of the transmission shaft axis differs from an input speed at the first end of the transmission shaft axis. ### Claim 2 (depends on 1) The snowmobile of claim 1, wherein the body defines a center plane being upright and containing the longitudinal axis, the transmission shaft axis being transverse to the center plane. ### Claim 3 (depends on 2) The snowmobile of claim 2, wherein the motor output, the transmission shaft and the drive wheel are disposed on only one side of the center plane. ### Claim 4 (depends on 3) The snowmobile of claim 3, wherein the drive wheel transmits torque to a drive belt, the drive belt in communication with a drive track wheel. ### Claim 5 (depends on 1) The snowmobile of claim 1, wherein the transmission shaft is supported at the first end by a first bearing and at the second end by a second bearing. ### Claim 6 (depends on 5) The snowmobile of claim 5, wherein the electric motor assembly includes a motor casing enclosing the electric motor, the motor casing being mounted to the body, wherein one of the body and the motor casing includes the first bearing. ### Claim 7 (depends on 5) The snowmobile of claim 5, wherein the body includes a drive belt case, the drive belt case including the second bearing. ### Claim 8 (depends on 7) The snowmobile of claim 7, wherein the drive belt case at least partially encloses the drive wheel and a drive track wheel. ### Claim 9 (depends on 5) The snowmobile of claim 5, wherein the transmission shaft is hard-mounted to the body via the first and second bearings, and the electric motor is soft-mounted to the body via one or more dampers. ### Claim 10 (depends on 1) The snowmobile of claim 1, comprising at least one brake actionable against the transmission shaft at a location between the first end and the second end. ### Claim 11 (depends on 1) The snowmobile of claim 1, wherein the motor output includes a female spline and the first end of the transmission shaft includes a male spline. ### Claim 12 (depends on 1) The snowmobile of claim 1, wherein the transmission shaft axis is collinear with a motor output axis. ### Claim 13 An electric vehicle comprising: a body extending along a longitudinal axis between a front end and a rear end; a battery pack mounted to the body and enclosing a plurality of battery modules; an electric motor assembly mounted to the body, the electric motor assembly including an electric motor configured to receive electrical energy from the plurality of battery modules to drive a motor output of the electric motor, the electric motor being soft-mounted to the body; and a transmission comprising a transmission shaft extending along a transmission shaft axis between a first end drivingly coupled to the motor output and a second end, wherein: the transmission shaft axis is co-axial with a motor output axis; and an output speed at the second end of the transmission shaft axis differs from an input speed at the first end of the transmission shaft axis. ### Claim 14 (depends on 13) The electric vehicle of claim 13, wherein the motor output includes a female spline and the first end of the transmission shaft includes a male spline. ### Claim 15 (depends on 13) The electric vehicle of claim 13, wherein the body defines a center plane being upright and containing the longitudinal axis, the transmission shaft axis being transverse to the center plane. ### Claim 16 (depends on 13) The electric vehicle of claim 13, wherein the transmission shaft is supported at the first end by a first bearing and at the second end by a second bearing. ### Claim 17 (depends on 16) The electric vehicle of claim 16, wherein the electric motor assembly includes a motor casing enclosing the electric motor, the motor casing being mounted to the body, wherein one of the body and the motor casing includes the first bearing. ### Claim 18 (depends on 16) The electric vehicle of claim 16, wherein the body includes a drive belt case, the drive belt case including the second bearing. ### Claim 19 A snowmobile comprising: a body extending along a longitudinal axis between a front end and a rear end; a battery pack mounted to the body and enclosing a plurality of battery modules; an electric motor assembly mounted to the body, the electric motor assembly including an electric motor configured to receive electrical energy from the plurality of battery modules to drive a motor output of the electric motor;
