Buick Riviera Specs, Engines & Dimensions (1971–1973) — Third Generation
The third-generation Buick Riviera is a big personal-luxury coupe, built around long-distance comfort rather than sharp handling. Here is what its powertrain means for you day to day.
A representative Buick Riviera engine here is the 7.5 AT: a large gasoline V8 paired with an automatic transmission and rear-wheel drive. Expect effortless low-speed pull and quiet cruising rather than urgency, with the drivetrain tuned for smooth, unhurried progress and heavy fuel consumption.
