LAZ-4206

In 1984, at the Avtoprom-84 exhibition, the Lviv Bus Plant announced the work begun on designing a new family of buses with the KamAZ-740.02 diesel engine, designed to replace the production of LAZ-695 N, LAZ-695R and LAZ-699 R models ^{[4 ]} .

In 1986, the All-Union Design and Experimental Institute of Bus Engineering began work on the creation of a 74-seat suburban bus LAZ-4206 to replace the model LAZ-695N ^[5] .

The project manager for the creation of LAZ-4206 and LAZ-4207 buses was the chief designer of the VKEI P. I. Prisyazhny ^[5] .

Since 1988, in order to increase the reliability of the electric network, on new buses of VKEI, wire harnesses were started to be placed in protective corrugated tubes. The first bus models to which this solution was applied were LAZ-4206 and LAZ-4207 (in which tubes with a diameter of 13–32 mm and a wall thickness of 0.5–0.7 mm were used) ^[6] .

In 1988, tests of pre-production samples LAZ-4206 and LAZ-4207 began ^[2] .

In 1991, it was decided to expand the production cooperation of the Lviv Automobile Plant, it was decided to transfer the production of 35 items of parts for LAZ buses to other specialized enterprises of the USSR. The production of the steering gear of the LAZ-4206 and LAZ-4207 buses and longitudinal steering rods was transferred to the Lviv Automobile and Tractor Spare Parts Plant ^[7] . Also, in 1991, at the Lviv Automobile Plant, it was decided to discontinue the LAZ-4202 1 to release production capacities (necessary to start mass production of the LAZ-4206 and LAZ-4207) ^[8] .

In addition, changes were made to the design of the bus: instead of the KamAZ-740.02 engine, it was decided to install the KamAZ-7408M engine (as a result, the maximum speed decreased slightly - from 117 to 115 km / h) ^[1] .

By 1992, the Lviv Bus Plant completed acceptance tests of the LAZ-4206 local-rural bus ^[9] , however, the production of a new model required production cooperation between enterprises of several republics of the USSR and serial production of the bus was not started.

The bus is a two-door, cabless, with a rear engine ^[2] .

It is equipped with a generator of model 65.3701 and a heater of model 14.8106 ^[2] .

Externally, the bus can be distinguished from LAZ-4207 by the absence of glazing at the bottom of the passenger doors and the inscription "4206" above the engine compartment cover. ^[ten]

• LAZ-4206 - the first version with a diesel engine (it was originally planned to install the KamAZ-740.02 engine, but later it was decided to install the KamAZ-7408M engine) ^[1]
• LAZ-4206G - gas cylinder version with a ZIL-375 engine, a set of gas equipment from the LAZ-695NG and gas cylinders located in the front pass-through luggage compartment ^[11]
