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.[1] Transmission is via a single-plate clutch[1] and four-speed gearbox with synchronised third and fourth gears.[2]
The wheels are pressed steel,[3] with drum brakes. The electrical system runs on 12 volts. The body has pressed steel panels on an ash frame.[1]
The original 1932 version of the Type 637 was built on a ladder frame. Its 1961 cc engine produced 37 hp (28 kW).[1]
In 1933 a trio of Type 637 cars won second, third and fourth place in the two-litre class of the Czechoslovak 1,000-mile race. In 1934 a Type 637 again won second place.[1]
But economic conditions were poor in the early 1930s, and Škoda sales were small. Only 11 were built.[1]
Types 637D and 637K
Škoda developed a new backbone chassis based on the successful Tatra concept. This had more torsional stiffness. The first Škoda to have a backbone chassis was the 420 Standard introduced in 1933.[4] In 1934 Škoda applied a larger version of the same chassis to the Type 637.[1]
At the same time Škoda increased the power of the Type 637 engine to 45 hp (34 kW), giving it a top speed of 110 km/h (68 mph).[1] The improved model was designated Type 637D.[2] Body options offered included a two-door or four-door sedan and a six-seat, "six-light" limousine with sunroof.[3] Sales improved slightly, numbering 39 cars.[1]
Škoda revised the model again as the 637K.[5] Sales remained low, with only 17 examples of this version being built.[1] Production ceased in 1935.[2]
