The latch assembly includes a housing, a latch accommodated in the housing by a latch shaft, and a ratchet accomodated in the housing by a ratchet shaft. The motorized closure assembly has an electric motor and a rotating lever for displacing the latch from a half-latched position to a full-latched position. The latch has a latch arm which substantially extends toward an outer panel of the door and overlaps with a rotating locus of the rotating lever.
