The sixth-generation Buick Riviera coupe traded the size of earlier cars for a tidier, front-wheel-drive layout, keeping the badge's quiet comfort while making everyday driving and parking noticeably easier.
Each Buick Riviera engine here is a gasoline V6 or V8 paired with an automatic transmission and front-wheel drive, a drivetrain chosen for smoothness rather than drama. The 3.8 AT suits relaxed cruising, while the 5.0 AT trades a little economy for stronger, quieter pulling power.
