The ZIL-4104 was a limousine built by ZIL from the late 1970s to the early 1980s, when it served as the transport of the elite of the Soviet Union.

This engine developed 315 hp SAE Gross at 4,400 revs per minute and a substantial 608 N⋅m (448 lb⋅ft) at 2500 rpm.

Among its special features were special laminated windscreen and triple-layered windows, supposedly offering protection from radiation in case of nuclear attack, plus duplicated systems, including dual ignition, two 74-amp batteries in parallel, and two fuel pumps.

[5] The console and dash were covered with Karelian birch 10 mm (0.39 in) thick, and the rear seat controlled radio (a Riga receiver), power windows, heater, and air conditioner; in the console in front was a Vilma cassette player.

[7] By 1984, a new three-speed automatic transmission had replaced the much outdated two-speed type that had been used by ZIL dating back to the first ZIL-111 in 1958.
