The Opel Kapitän is an executive car made in several different generations by the German car manufacturer Opel from 1938 to 1970.
Kapitän (1953–1958)
In November 1953, Opel launched a completely new Kapitän that was longer and wider than its predecessor. Carried over was the six-cylinder engine, though its compression ratio was raised to 7.0:1, giving 68 PS (50 kW; 67 hp) initially. For 1955, output rose to 71 PS (52 kW; 70 hp) and it was further enhanced to 75 PS (55 kW; 74 hp) for 1956. The ´54 featured a revised rear live axle, a rear stabilizing bar and slightly enlarged drum brakes.
Model year 1956 saw a mild facelift with a more up-to-date grille, bezeled headlamps, larger front indicator lights and revised side trim. The ´56 reached a top speed of 140 km/h (87.0 mph) and consumed 13 L/100 km (22 mpg‑imp; 18 mpg‑US).
From May 1957, a semi-automatic three-speed overdrive transmission with an additional fourth gear became available on request.
From November 1953 to February 1958, 154,098 Kapitäns were built. In its time, this generation was the third-most popular car in Germany behind Volkswagen´s Beetle and Opel's own Rekord (Oswald, p. 73).
