History of the Opel Kapitän

Introduced in 1938 as Opel’s new upper-class vehicle, the Kapitän replaced the Opel Super 6. It stood out as the last civilian production model before the outbreak of World War II, released with a steel unitary body and advanced independent front suspension with double wishbones—a rarity for the era. Early versions were available as two- or four-door saloons, and even as a rare cabriolet variant. Its production was interrupted by the war, with over 25,000 units built by 1940. Post-war, Opel resumed production in 1948, introducing the four-door Kapitän with front-hinged doors at the front and rear-hinged at the back (often referred to as 'suicide doors'). Its design drew heavy influence from its parent company GM, echoing the lines of American vehicles.

Model history

The Kapitän saw multiple series: The pre-war models until 1940, then the near-identical post-war models from 1948. From 1950, updates featured a column shift and renewed interiors; in 1954, the Kapitän adopted a new ponton body style shaped by American design influences. The P 2.5 'Schlüsselloch' (keyhole) model is the rarest, built for just 11 months. In 1958, the P 2.5 introduced a more chromed, elongated design, followed swiftly by the P 2.6 which offered enhanced practicality and a modernised, more European appearance. The KAD line (Kapitän, Admiral, Diplomat) began in 1964, positioning the Kapitän as the entry-level luxury vehicle. The series concluded in 1970 with the Kapitän B, ending its distinguished run.

Special Editions and Collectible Models

The rare Kapitän P 2.5 'Schlüsselloch' (produced for about 11 months with under 35,000 units) stands out as the scarcest. Cabriolet models from the early series and special export editions (including versions for the US market) are highly prized among collectors for their limited numbers and unique specification packages.

Weak Spots and Common Issues

Authenticity and originality are central for Kapitän collectibility. Areas to scrutinise include the integrity of bodywork restoration, especially in hidden areas susceptible to corrosion. Later models often had electrical upgrades such as 12V conversions, and enthusiasts should check the quality of these adaptations. Original documentation, including manuals and maintenance logs, add to a car’s value. Replacement parts and restoration spares are growing harder to locate, especially for rare trims and export specifications. mechanicals—engine, gearbox, suspension—tend to be robust, but expect most examples to have had extensive refurbishment.

Engine and Performance, Transmission and Handling

With smooth-running six-cylinder engines (initially 2.5L, later up to 2.8L), the Kapitän delivered outputs from 55 PS to 140 PS, placing it ahead of many contemporaries in comfort and long-distance ability. The ride is characterised by its independent front suspension with double wishbones and a robust live axle at the rear, which provided a soft yet predictable handling profile. Gearboxes ranged from 3- and 4-speed manuals to later automatic options, notably on luxury models.
