Tatra does not build many cars like the Tatra 17: a 2+2, Roadster, Town car, Touring on Backbone chassis with 1930 cc Tatra 17 Straight-six engine, built from 1925 to 1929 the vintage years, when coachbuilders still shaped most of what was sold.
The background
The Tatra 17 is an automobile produced by the Czech manufacturer Tatra between 1925 and 1929. It was the company's top-end model, and was sold alongside the Tatra 12 economy car and the Tatra 30 executive car.
The engineering
Under the skin sits 1930 cc Tatra 17 Straight-six engine; other versions carried different engines, listed in the specification table below. Kerb weight is 1300-1500 kg. The gearbox is 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 3450 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
Where it sits in Tatra's history is not in doubt: the Tatra 12 / Tatra 20 / NW T came before it; the Tatra 31 followed it; it was built at Kopřivnice, Czech Republic (Czechoslovakia at the time). On a showroom list of its day it stood against the Chrysler Chrysler, the Opel 10/40 PS, the Rolls-Royce Phantom I. Its Tatra stablemates include the Tatra 10 and the Tatra 600 kabriolet.
The money
There is no federal ownership record for the Tatra 17 — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
