When "Perestroika" - a term coined by Mikhail Gorbachev, was a trend in one large country, another "Perestroika" which literary means "rebuilding" was conceived by the engineers of Minsk Auto Factory or MAZ, one of the largest Soviet truck manufacturers. This somehow unusual looking truck is "Perestroika" itself. You might have already noticed a gap between the truck's cab and the headlights, that is because the truck was not one solid truck but rather a set of modules or blocks that could be conjoined. Let me try to explain what this Perestroika truck was about.
As far as I understood after reading the Russian materials connected with this vehicle, the idea behind Perestroika was to make a truck that had the engine and drive train separated from the cargo part and from the cab. Those parts could be connected like blocks to build the truck of a given load and power train capability on the spot. So one could combine, for example, a few "engine" modules to get a more powerful truck or
What they also mention is the attempt to build a "transcontinental" truck that could cross the vast Soviet territory and be rebuilt easily to match the current location, load and needs.
So that's why the term "Perestroika" was used as a model description.
