Background

After the failure of the Disk, Zbrojovka was determined that its next car design would be a success. The company had a new engineering team that included the talented František Mackrle and he designed two new designs, both named Z 26, with different engine sizes. The Board liked the more powerful version, but required the prototype to undergo rigorous testing, including driving over across Europe, crossing the Dolomite and Alps and driving as far as Hamburg. The car passed the tests and entered production as the 4/18 or Z 18 in 1925.
