The ZIL 4906(1) is based on the Zil 4972
See http://legion.wplus.net/guide/army/tr/zil.html on the site of Roman Astakhoff for more info on the 4972.
zil 4906 This amphib is a 6WD with 4WS, the front and rear wheels steer.
The fibreglass body, is air conditioned.
The tyre pressure control from the cab.
The uniform arrangement of the axles on the machine (2400+2400 mm) allows to overcome trenches more than 1.5 mtr width, and vertical earth and snow barriers up to 1 mtr.
It has a V8 petrol engine ZIL-508.10 with 150 hp, or a diesel engine ZIL-0550.30.
The manual gearbox has a 5 gear + 2 gear low and high.
Top speed on road is 68 km/h. Average with cargo is 20 km/h
Top speed on water is 9 km/h. Propulsion by water jet(s) ?
Transmission is executed in a H-circuit (just like the Alvis Stalwart).
But the ZIL has hydraulic couplings on the axles to prevent winding up of the transmission on asphalt roads.

The way it works is that a coupling lets a very small difference in the axle revs pass but that is only a fraction of the power needed to drive the vehicle forward.
