The sixth-generation Buick Regal, after its third restyling, continues as a refined midsize sedan. This update keeps the focus on comfortable daily driving with efficient powertrains and a composed ride.
The Buick Regal engine lineup centers on turbocharged four-cylinder gasoline units paired with automatic transmissions and front-wheel drive. These powertrains balance smooth response with everyday efficiency. For example, a 1.5-liter turbo and a 2.0-liter engine are available, each matched to a conventional automatic, delivering relaxed acceleration and predictable highway cruising. This drivetrain setup suits drivers who value low-effort operation and consistent fuel economy in a midsize sedan.
