LiAZ-677B - modification for suburban transportation. Buses of this modification were distinguished by a 4-row seat layout, the absence of a rear storage area (passenger seats were installed instead) and the same floor level throughout the entire cabin. Also, unlike a city bus, commuter buses had a spare wheel, which was located 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-677 was 35, the nominal capacity was 67 passengers, and the maximum capacity was 87 passengers.
