Buick Riviera Specs, Engines & Dimensions (1966–1970) — Second Generation
The second-generation Buick Riviera kept its personal-luxury character in coupe form, pairing long-hood proportions with a big, relaxed V8. It was built for effortless highway cruising rather than sharp cornering or fuel economy.
A representative Buick Riviera engine choice is the 7.5 gasoline V8 with automatic transmission and rear-wheel drive. Large-displacement engines like this deliver strong low-speed pull, so the powertrain rarely needs to work hard; expect smooth, quiet acceleration and correspondingly high fuel consumption.
