From 1978 to 1994, LiAZ 677MB was produced. Modification for suburban transportation. The buses of this modification were distinguished by a 4-row seating layout, the absence of a rear storage area (passenger seats were installed instead) and the same floor level throughout the cabin. Also, unlike the city bus, suburban buses had a spare wheel, which was placed either under the floor on the rear overhang or on a bracket outside on the rear wall of the bus. The number of seats in the LiAZ-677MB was 35, the nominal capacity was 67 passengers, and the maximum capacity was 87 passengers.
