|Body and chassis|
The Kapitän was the last new Opel model to appear before the outbreak of the Second World War, developed during 1938 and launched in the spring of 1939 at the Geneva motor show. The first Kapitän was available in many different body styles, the most popular one being the 4-door saloon. 2-door coupé cabriolets were also built. The pre-war Kapitän featured a unitary body, a modern feature for its time. The car inherited its 2.5-litre engine from its predecessor: in this application a maximum speed of 118 km/h (73 mph) was reported.
Civilian automobile production by Opel ceased in the Fall / Autumn of 1940, by which time 25,371 Kapitäns had been produced: a further three were assembled during 1943, giving a total production volume for the version launched in 1939 of 25,374. In addition, 2 were assembled in 1946, and one in 1947, but these were not officially recorded in the statistics.
Included in the production total were 248 of the two-seater cabriolets built for Opel by independent coach builders Gläser of Dresden and Hebmüller of Wülfrath in Wuppertal. There would, however, be no resurrection for the cabriolet Kapitäns in 1948 when the sedan / saloon version was reintroduced.
|Engine||2.5 l-I6, 55 PS/54 hp|
|Wheelbase||2,695 mm (106.1 in)|
|Length||4,620 mm (181.9 in)|
|Width||1,660 mm (65.4 in)|
|Height||1,640 mm (64.6 in)|
|Curb weight||1,230 kg (2,711.7 lb)|
In October 1948, the Kapitän was re-introduced as Germany's first post-war six-cylinder automobile. Initial production was reserved for the occupying powers, but sales to private customers started in 1949. There was no sign of the wide range of coupe and cabriolet bodies that had broadened the model's appeal in the 1930s: the 1948 Kapitän was offered only as a saloon/sedan, based on the 1939 version.
The main differences were round headlights as opposed to hexagonal ones. From May 1950 the shifter was relocated from the floor to the steering column. The first post-war Kapitän reached a top speed of 126 km/h (78.3 mph), needed 29 seconds to reach 100 km/h (62 mph) and consumed 13 litres per 100 kilometres (22 mpg-imp; 18 mpg-US) in the process.
Up to February 1951, 30,431 Kapitäns were built.
|Engine||2.5 l-I6, 58 PS/57 hp|
|Wheelbase||2,695 mm (106.1 in)|
|Length||4,715 mm (185.6 in)|
|Width||1,720 mm (67.7 in)|
|Height||1,625 mm (64.0 in)|
|Curb weight||1,240 kg (2,733.7 lb)|
The 1951 Kapitän, introduced in March 1951, was a stylistically slightly modernized version of the old model; technically it was much the same. The engine's compression ratio rose from 6.0:1 to 6.25 to 1, its output from 55 PS (40 kW; 54 hp) to 58 PS (43 kW; 57 hp).
From the outside the car was readily distinguished from the first post-war Kapitäns, thanks to an abundance of chrome and a US style grill at the front.
From March 1951 up to July 1953, Opel built 48,562 cars of this series.
|Engine||2.5 l-I6, 68-75 PS (67-74 hp)|
|Transmission||3-speed manual, 4-speed-overdrive transmission|
|Wheelbase||2,750 mm (108.3 in)|
|Length||4,710 mm (185.4 in)-4,735 mm (186.4 in)|
|Width||1,760 mm (69.3 in)|
|Height||1,600 mm (63.0 in)-1,560 mm (61.4 in)|
|Curb weight||1,250 kg (2,755.8 lb)-1,300 kg (2,866.0 lb)|
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 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 3-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).
|Engine||2.5 l-I6, 80 PS (79 hp)|
|Wheelbase||2,800 mm (110.2 in)|
|Length||4,764 mm (187.6 in)|
|Width||1,785 mm (70.3 in)|
|Height||1,500 mm (59.1 in)|
|Curb weight||1,310 kg (2,888.1 lb)|
The 1958 Kapitän (series P1), introduced in June 1958, was both wider and lower than its predecessor, and featured panoramic windows. Although it won plaudits in some quarters for its American-inspired "dream-car" styling, but there were also critics who pointed out that the extent of the wrap-around front and rear windows along with the slope of the rear roof-line retricted the driver's view out unnecessarily and made the rear doors very narrow: many back seat passengers, once they had negotiated their way onto the back seat had issues 
This time, the 2,473 cc six cylinder engine had its maximum output raised to 80 PS (59 kW; 79 hp) at 4,100 rpm. Wheelbase, track widths, length and width were all slightly increased, while a flatter roof made the car some 6 centimetres (2.4 in) lower.
The P1 was built only for one year. From June 1958 to June 1959, 34,282 were produced, which was fewer cars than the annualized output of either its direct predecessor or of its direct successor.
Kapitän P2 (1959–1963)
|Engine||2.6 l-I6, 90 PS (89 hp)|
|Wheelbase||2,800 mm (110.2 in)|
|Length||4,831 mm (190.2 in)|
|Width||1,812 mm (71.3 in)|
|Height||1,512 mm (59.5 in)|
|Curb weight||1,340 kg (2,954.2 lb)|
The P2 Kapitän came to market in August 1959 and while it still had the panoramic windscreen, it gained a new grille and a redone body with a more angular roof and a new rear. It was driven by a stronger new, oversquare 2.6-liter-inline six (bore x stroke: 85 x 76.5 instead of 80 x 82 mm), still of OHV and pushrod design. Carried over were the 3-speed and 4-speed overdrive transmission; the latter was replaced from December 1960 by a version of GM´s 3-speed Turbo-Hydramatic automatic.
The P2 climbed to a top speed of 150 km/h (93.2 mph), reached 100 km/h (62 mph) in 16 seconds and consumed 12 L/100 km (24 mpg-imp; 20 mpg-US).
From August 1959 to December 1963, Opel built 145,618 units of this Kapitän series. No other Opel Kapitän model, before or subsequently, achieved such a high production level.
The large Opels were never dominating players in their market segment on the same scale as the smaller Rekord and Kadett models, possibly due to the strength of Mercedes-Benz in the big car sector. Nevertheless the highpoint for the big Opels was 1960 when together the Kapitän and Admiral were Europe's top-selling six-cylinder saloons, with nearly 48,000 sold.
Kapitän A (1964–1968)
|Wheelbase||2,845 mm (112.0 in)|
|Length||4,948 mm (194.8 in)|
|Width||1,902 mm (74.9 in)|
|Height||1,445 mm (56.9 in)|
|Curb weight||1,380 kg (3,042.4 lb) - 1,550 kg (3,417.2 lb)|
It was powered by the same engines as the contemporary Opel Admiral, namely a 2.6 l-inline six or a 2.8 l-six; a few Kapitäns even received the Chevrolet-sourced 4.6 l-V8. For the Austrian market, 580 Kapitän and Admiral models received a 2.5 l-six with an output of 112 PS (82 kW; 110 hp) in 1966/67.
Like its more expensive brethren, the Kapitän was reworked in late 1967 and received rub strips, a new ZF steering and a collapsible steering column. At the same time, a new HL (Hochleistung = high-performance) version of the 2.8 l-six became available that put out 140 PS (103 kW; 138 hp).
Sales of the Kapitän A fell sharply off; up to its discontinuation in November 1968, a total of 24,249 cars left the factory.
Kapitän B (1969–1970)
|Engine||2.8 L CIH I6 (gasoline)|
|Wheelbase||2,845 mm (112.0 in)|
|Length||4,907 mm (193.2 in)|
|Width||1,852 mm (72.9 in)|
|Height||1,450 mm (57.1 in)|
|Curb weight||1,475 kg (3,251.8 lb) - 1,495 kg (3,295.9 lb)|
The Kapitän B was introduced in 1969 and was the last car bearing the Kapitän name. Engine options included a 1-bbl 2.8 l-inline six or a 2-bbl version of same, coupled with a 4-speed manual or Opel's 3-speed automatic transmission.
Production ended in May 1970. The Admiral and Diplomat lived on for another seven years until they were replaced by the Senator in 1978.
Just 4,976 Kapitan B models were built in 15 months.
