Opel Diplomat

The Opel Diplomat is a luxury car manufactured by Opel. Opel's top-ranging models were traditionally the Admiral and Kapitän, introduced in 1938 and 1937 respectively.

In 1964, these models were joined, in the so-called "KAD" (Kapitän, Admiral, Diplomat) range, by the new Opel Diplomat. In most respects the three were badge-engineered versions of the same new vehicle.

Diplomat A (1964–1968)

In February 1964 Opel introduced a new range of flagship models as successors to the Opel Kapitän P-LV of 1959/1963. At launch these KAD models (Opel Kapitän, Admiral and Diplomat; also referred to as "The Big Three" by Opel) were available with 2.6 litre or 2.8 litre, in-line six-cylinder petrol engines (100 or 125 PS/99 or 123 hp), or a V8-Chevrolet small-block engine 283 (4.6 litre) teamed with a two-speed Powerglide automatic transmission (190 PS/187 hp). The latter engine was supplanted in the saloon by the V8-Chevrolet small-block Type 327 (5.4 litre) in October 1966 (230 PS/227 hp). As the company's range-topping model, the Diplomat was available only with the V-8.
