Buick Century Engines and Transmissions

Each Buick Century engine here is a gasoline unit paired with an automatic transmission and rear-wheel drive, a powertrain layout tuned for smooth cruising rather than sharp response. Examples such as the 4.3 AT, 4.9 AT and 5.0 AT show how the drivetrain scales with displacement, larger units pulling more easily at low revs.
