1. A system, comprising:
an electric drivetrain comprising a differential; and
a disconnect device arranged in a transmission housing and coupled to the differential via a dog clutch, the disconnect device comprising a plurality of cam ring lugs engaged with a differential case, wherein each of the plurality of cam ring lugs is asymmetric, wherein each of the plurality of cam ring lugs comprises a drive flank and a coast flank, wherein a drive angle between the drive flank and the differential case is greater than a coast angle between the coast flank and the differential case, and wherein a drive gap is present when the differential case touches the coast flank during a coast condition, and wherein a coast gap is present when the differential case touches the drive flank during a drive condition, wherein the coast condition comprises decoupling a magnet motor of the electric drivetrain from drive wheels.
