VW Kubelwagen Type 82 was a work-horse of German army through all the WWII. It was used on all the theaters in different terrains and climate conditions. Dunes of Africa as well as mug and deep snow of Russia showed the need to improve its off-road capabilities.
In 1942, on WV plant in Schtutgart, the works on Type 155 Schneeketten (half-track) Kubelwagen had begun.
There were several quite different variants of suspension developed (possibly consecutively fitted to the same prototype).
Some of them utilized parts of agricultural tractors produced by Porsche.

 Typ-155/0 initial prototype.                          Typ-155/1.  Typ-155/2. Very simple type.                         Typ-155/3a.  Typ-155/3b. Front skis added.                       Typ-155/4b. Simplified Horstmann design.

Finally, the version 155/4c was developed:

The modifications necessary to the standard Kubelwagen were extensive:
the nose-skid was mounted, the brakes reinforced, the differentials changed to otpimize engine performance.
In 1944 it was extensively tested along with Sd.Kfz.2 Kettenkrad to compare.

That trials proved that the Type 155 was able to cover the most difficult terrain,
but the resulting vehicle was both very slow and forbiddingly inefficient -
top speed - 8 km/h, fuel consumption - 150 liters / 100 km. That was unacceptable.
Type 155 has been never produced in series.
