Opel Diplomat Specs, Engines & Dimensions (1964–1968) — First Generation
The first-generation Opel Diplomat brings classic executive-car appeal to Coupe and Sedan bodies. If you’re considering one, the powertrain deserves attention alongside the body style, particularly when weighing how you’ll use the car.
Opel Diplomat engine options represented by the selected Sedan examples include the 2.6 AT, 2.8 AT and 4.6 AT. All combine gasoline power with an automatic transmission and rear-wheel drive. Automatic shifting reduces your workload in traffic, while this drivetrain layout leaves the front wheels to steer and the rear wheels to propel the car.
