About the Opel Admiral B
The Opel Admiral B was the mid-range offering in the 'KAD' (Kapitän, Admiral, Diplomat) lineup, Opel's attempt to compete with the Mercedes-Benz S-Class. While it shared its body and sophisticated De Dion rear suspension with the flagship Diplomat, the Admiral focused on six-cylinder efficiency rather than V8 power. The 2.8-litre cam-in-head engine provided smooth, reliable performance suited for high-speed cruising on the Autobahn. Despite its technical competence and American-influenced styling, it struggled to overcome the brand prestige of its premium German rivals, making it a rare and distinctive choice for modern collectors.
