Opel Super Six Cabrio at the Josefuv Dul Car Show, Liberecky Kraj, Bohemia(CZ), 2015

When I first spotted this car, I thought that it was a Chevy Master, as I know that at least one Master is based in the Czech Republic. However, this is actually an Opel Super 6, and the resemblence to a Chevy is probably down to the fact that Opel were owned by General Motors from 1931 to 2017.

The Opel Super 6, as the name implies, was an upgraded Opel 6, referring to the car's I-6 engine. The earlier 6 was also sometimes called an Opel 2.0L as a result. The Super 6 came with a 2.5L I-6 as standard, and could be order as a 4-door sedan, a 2-door sedan, or as a 2-door cabriolet, seen here. It was also possible to order it as a sort of pseudo-sports car, as a number of coachbuilders such as Kuhn made sports car bodies for the Opel Super 6 chassis. At the time, Opel were experimenting with early unibody (monocoque) construction with the Opel Olympia, but the continued use of body-on-frame construction in the Super 6 enabled custom bodies to be fitted.

Although the Opel Super 6 wasn't horribly slow for the 1930's, it also wasn't comparable to a Mercedes, a BMW, or even a V-8 Ford, as even with its upgraded 2.5L, 54 horsepower engine, it was only capable of 115 Km/h. It also only remained in production for two model years, 1937 and 1938, before being replaced by the much longer-lived Opel Kapitan, which stayed in production with various facelifts until 1970.
