Originally developed as a smaller vehicle for sale alongside the Z 4, 400 of the car were sold between 1935 and 1938.

The car was of conventional design and powered by liquid-cooled two stroke two cylinder engine, which propelled it to a top speed of 90 km/h (56 mph).

Designed as a smaller complement to the Zbrojovka Z 4, the Z 6 Hurvínek was a two-door sedan of conventional front-engine, front-wheel-drive layout.

[2] The Z 5 Express could reach a top speed of 90 km/h (56 mph) and had a typical fuel consumption of between 8 L/100 km (35 mpg‑imp; 29 mpg‑US), which meant that the 20 L (4.4 imp gal; 5.3 US gal) fuel tank was sufficient to drive from Prague to Brno.

[1] The car was announced in October 1935 at the Prague Motor Show and sales continued after the factory moved to military production from 1936, the last car being sold in 1938.
