Opel Diplomat Engines and Transmissions

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.
