Abstract:
A number of variations may include a product that may include a power transfer assembly. A gear train may have multiple gears and may provide a first stage gearing that may have a fixed gear ratio. At least one planetary gear set may provide a second stage gearing that may have multiple gear ratios. An electric machine may selectively provide input to the first stage gearing. A differential unit may selectively receive output from the planetary gear set. An engagement mechanism may selectively connect the differential unit with the second stage gearing in each of a high range mode and a low range mode.
