The Škoda 637 is a Sedan, limousine from Škoda Auto, built from 1932 to 1935, when streamlining and independent suspension were arriving together. Under the bonnet: Six-cylinder 1961 cc Flathead engine.
The story
The Škoda 637 is a Czechoslovak mid-size car that was made by Škoda from 1932 to 1935. The car has a 1961 cc, six-cylinder, sidevalve engine, which is an enlarged version of the 1792 cc engine introduced in the Škoda 633 in 1931. Transmission is via a single-plate clutch and four-speed gearbox with synchronised third and fourth gears. The wheels are pressed steel, with drum brakes. The electrical system runs on 12 volts. The body has pressed steel panels on an ash frame.
What is underneath
Power comes from Six-cylinder 1961 cc Flathead engine; other versions carried different engines, listed in the specification table below. It shifts through a Single-plate clutch / 4-speed gearbox. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Its place in the line
Its family tree is legible: it took over from the Škoda 633 (1931); its successor was the Škoda Superb (1934–1949)#First and second generation (Type 640) / Škoda Superb (1934) / Škoda Favorit (1936–1941) / Škoda Favorit (1936); assembly was at Mladá Boleslav, Czechoslovakia. Its contemporaries in the catalogue — the Chevrolet Suburban, the Bugatti Type 57, the DKW F2 — show what else the money bought that year. Nearby in the Škoda Auto catalogue sit the HZS-1 and the Trekka.
What it costs now
MotorJury scores cars on the United States complaint and recall record, and the Škoda 637 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.
