Kapitän / Admiral / Diplomat / Senator / Monza


Kapitän, 1951

As the 1951 Olympia the 1951 Kapitän was just a face lifted pre-war Kapitän. It was the first 6-cylinder built in Germany after WW-2.


Kapitän, 1956

The 1956 Kapitän was a face lifted version of the first ponton body Kapitän.


Kapitän P I, 1958

Although the Kapitän P I is one of the best looking Kapitäns ever built, it was the "Edsel" of this model. With looks being more important than practicality the rear doors were too narrow, which was the kiss of death for a car often used by people with a Chauffeur. They didn't like to have a hard time to crawl in and out of the car's rear doors.


Kapitän P II, 1959

If the P I was the Edsel, the P II was the most successful Kapitän ever. With this Kapitän Opel also introduced it's first automatic transmission.

The car with the 6-cylinder's displacement increased to 2.6 liter it had only 90 HP. The reason for this is that it was a torque optimized engine with the maximum of 190 Nm available from 1300 to 2500 RPM. The car could be accelerated from a standstill to 150 km/h (93 mph) top speed in highest gear.


Kapitän / Admiral / Diplomat A, 1964

Although great cars, the K.A.D.-A series couldn't continue the P II's success. The phrase "bigger is not always better" applies to these Opels more than to any other Opel.

The CIH engine was introduced for the first time as a 2.8 liter 125 HP version in the Admiral. It would make it all the way into the 90s with the most powerful version being the 4.0 liter 24 valve 272 HP Irmscher engine. The Diplomat was available with a 4.6 liter 190 HP V8, the Diplomat Coupé even had a 5.4 liter 230 HP V8 and a top speed of 205 km/h (127 mph).

This car competed with the BMW V8 (nicknamed "Baroque Angel") - 140 HP and the Mercedes 300 SE, a
3 liter 160 HP straight six. It seems by dwarfing the competition Opel had done too much.

The Coupés are highly desirable collector cars today. The one existing Cabriolet has recently been restored.


Kapitän / Admiral / Diplomat B, 1969

Finally with the K.A.D.-B series the cars got an independent rear wheel suspension. Opel gave them a De-Dion rear axle.

Although visibly smaller and much more European in design the cars were unable to make up the ground lost by the A models.

The name Kapitän was dropped some time around 1970 and only Admiral and Diplomat remained.


Senator / Monza A, 1978

With the introduction of the Senator and Monza Opel - although not admitting it - retired from the "big-car" market. The most powerful engine available now was a 3.0 E with 180 HP that accelerated the Monza in 8.5 seconds to 100 km/h (62 mph) and gave it a top speed of 215 km/h (133 mph). Back then this was Porsche 928 territory!!!

Still the cars were considered luxury Rekords by some people, which was not totally wrong. The body was lengthened in the front and the back, a third side window was added to the Senator, but the front doors were the same as in the Rekord, while the rear doors were the same as in the Rekord wagon and the cars had the same width and wheelbase.

The cars sold reasonably well, but still could not regain the ground lost after the Kapitän P II was discontinued.



Senator / Monza A, 1982

The Senator and Monza A got a face lift in 1982 after the looks of the cars became quickly outdated. It was the time when chrome almost completely vanished from cars and although looking very modern in 1978 the changing taste of the time made them look oldfashioned very quickly.

The Monza, which sort of carried on the heritage of the original Commodore also revived the GS/E designation as the top-of-the-line Monza. Unfortunately the planned and tested 200 HP engine didn't become available. This was the last Monza.


Senator B, 1987

As the Senator A and the Rekord E were close relatives, the Omega A and the Senator B were even closer related. Although it came with the great 3.0 i 24 valve engine with 204 HP and even with a 4.0 i 272 HP engine made by Irmscher, the car didn't sell very well. Certainly the "icecube tray" grille and the rather boring design didn't help.

As with the Commodore C the Senator's niche had become too small. Not being a real "big car" because it had the same wheelbase as the Omega A, Opel finally stopped competing in a market segment that it had once dominated, when the Kapitän sold third after the VW Beetle and the Opel Rekord.
