Start with what the Tatra 54 is: a 2+2, Sedan with 1.5L (1465 , built from 1931 to 1934, when streamlining and independent suspension were arriving together. What it meant takes a little longer.
The story
The Tatra 54 is an automobile launched by Tatra in 1931. An economy version of the Tatra 52, it was replaced in 1933 by the Tatra 75. The car was powered by an ohv air-cooled four-cylinder boxer motor of 1465 cc, positioned at the front, and giving a claimed output of 22 PS (16 kW; 22 hp).
Power was delivered to the rear wheels via a four-speed gear-box. The Tatra 54 featured a central "backbone chassis" a hallmark of Design Chief Ledwinka: the front axle was supported by a transverse leaf spring while a second transverse leaf spring supported the swing rear axle. Various four- and six-seater saloon bodies were available with two or four doors. During its three-year production run, 1510 Tatra 54s were built.
What is underneath
The engine is 1.5L (1465 other versions carried different engines, listed in the specification table below. Drive goes through a 4-speed manual. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is 2820 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Its place in the line
In the Tatra line-up the Tatra 54 has a clear place: it replaced the Tatra 30; it handed the line to the Tatra 75; the factory was Kopřivnice, Czechoslovakia. The cars a buyer would have weighed it against include the Chevrolet Suburban, the Bugatti Type 57, the Triumph Super 9. Nearby in the Tatra catalogue sit the Tatra 10 and the Tatra 600 kabriolet.
Owning one today
MotorJury scores cars on the United States complaint and recall record, and the Tatra 54 has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
