Opel Diplomat Engines and Transmissions

An Opel Diplomat engine in this generation is a gasoline unit sending power to the rear wheels. Pick the 2.8 MT sedan for a manual transmission, or the 2.8 AT and 5.4 AT if an automatic better suits your drivetrain. These versions illustrate typical powertrain choices, not the full range.
