The Tatra 26/30 is a 6x4 automobile produced by the Czech manufacturer Tatra between 1927 and 1933. Three prototypes were developed on the basis of the T 12 and given the designation T26. However, tests showed that the engine from the T12 did not have enough power. It was replaced with a Tatra 30 engine and the designation of the vehicle was changed to Tatra 26/30.
The 26/30 served in several roles, both in military and in civilian use. These included use as a troop transport, command car, ambulance, and bus.
Four Tatra 26/52 prototypes with the more powerful Tatra 52 engine were produced in 1932 as an intermediary stage between the 26/30 and the Tatra 72, one of which was converted into a fire truck.
