In June 2026, a series of test drives of the ZVEZDA HX4 cargo model took place on marshy terrain at the test site.
On June 11, the plant showed the vehicle moving with five tonnes of cargo. On June 14, the next stage was published: a drive over test marshy sections with six tonnes on board.
This is the result of a specific test drive. It does not replace the vehicle's rated payload capacity, which is specified separately in the technical documentation.
