Buick Roadmaster Specs, Engines & Dimensions (1991–1996)

Buick Roadmaster Engines and Transmissions

The Buick Roadmaster engine story centres on large-displacement V8 power, as in the 5.7 AT Sedan, which pairs a gasoline unit with an automatic transmission and rear-wheel drive. This powertrain prioritises quiet, low-effort torque, so the drivetrain pulls easily from low revs and cruises unhurried.
