Abstract
A utility vehicle includes a first axle, a second axle, an electric motor, an internal combustion engine, and a torque transfer device. The first axle is coupled to first and second wheels. The second axle is coupled to third and fourth wheels. The electric motor drives the first axle in a first direction and a second direction at different times. The internal combustion engine drives a transmission output shaft in one direction. The torque transfer device selectively drives the second axle in the first direction in response to rotation of the transmission output shaft in the one direction. The torque transfer device also selectively drives the second axle in the second direction in response to rotation of the transmission output shaft in the one direction.
