Opel Diplomat (Diplomat B, 1969 to 1977)

The Diplomat B was the second series of the Opel Diplomat, introduced in March 1969 as part of a new line of KAD models with new bodies and a more sophisticated chassis with a De Dion tube rear axle. The cars were slightly smaller than their predecessors. The Diplomat could be had with a fuel-injected version of the 2.8 L inline six, the Diplomat E, or with Chevrolet's 327 V8, the Diplomat V8, now coupled to a three-speed TH-400 Turbo-Hydramatic. The body was a typical General Motors style that strongly resembled the Holden Brougham. It was never built in right-hand drive nor sold as a Vauxhall, and from May 1973 a long-wheelbase V8 was offered to compete with the Mercedes-Benz SEL models.
