The MAZ-6440 truck ( Russian МАЗ-6440 , German transcription actually MAS-6440) is a prototype truck from the Belarusian vehicle manufacturer Minski Avtomobilny Zavod , which was mainly developed in 2011. The vehicle is currently not in series production and there are no known plans for a possible series production.

description

MAZ made the first announcements about the development of a new tractor for long-distance transport in December 2010. Six months later, on May 17, 2011, the prototype MAZ-6440RA was presented in Minsk. It has some special features compared to other tractor units from the manufacturer. For example, it is the only model that has a long-hood design. The production of long-hooded tractors is an exception today in Europe and also in Russia, for which MAZ gave no justification. In addition, with a curb weight of almost 11.5 tons, the vehicle is relatively heavy compared to standard tractors. The prototype was designed for a technically permissible total mass of 63 tons, although in none of the countries in which the manufacturer has a larger sales market such a total mass would be permitted in road traffic without special permits.

In contrast to the manufacturer's standard tractors, the tractor's engine is a V8 diesel engine. The one-off production with 600 hp was supplied by Minski Motorny Sawod (MMS). The transmission comes from the American company Allison Transmission .

A revised version was presented around 10 months after the first version was presented. The most important change was a new body shape with more curved lines. Otherwise there are hardly any differences between version one and two.
