PZInż Zawrat
motor vehicle
Zawrat (also known as PZInż. 153) was a Polish bus brand produced by the Państwowe Zakłady Inżynieryjne (PZInż) holding between 1936 and 1937 for the city of Warsaw. Only 18 buses were completed before the series was cancelled. The last Zawrat bus remained in service in Warsaw until 1949.
The bus was based on a license-built chassis of the Saurer 3CT1D bus designed by Swiss Saurer company and a six-cylinder Saurer BLD engine, also license-built in Poland. The license for the chassis was bought in 1932 and initially 70 Saurer 3CT1D buses were completed entirely of Swiss-made parts. Until 1934 additional 43 chassis were completed, partially of parts produced in Poland. Some of those were finished with bus bodies, others were converted to 5-tonne lorries for the Polish Army.
In 1936 the PZInż designed a new all-metal body for the Saurer 3CT1D and named the new bus "Zawrat" after the pass in Tatra Mountains. The bus had two doors and seats for 50 passengers.

Why this record matters
The phrase “motor vehicle” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Nov 1, 2025. The linked authority identifier is Q9387606. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1936, 1937, 1949 and 1932.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
