Abstract
A gearbox includes a first shaft operatively coupled to an output of an engine, with the first shaft having a first longitudinal axis. A second shaft is operatively coupled to a driveshaft of an electric machine, the second shaft having a second longitudinal axis. The second longitudinal axis is non-coaxial with the first longitudinal axis. A geartrain operatively couples the first and second shafts. The geartrain is structured to passively switch between a first gear ratio and a different second gear ratio.
