QuietTuned for silent ride, comfort
Like all other Buick models, Terraza benefits from QuietTuning, a comprehensive engineering program throughout the entire vehicle to ensure a silent ride. This includes new engine isolation measures and acoustic treatments within the body structure to give this new crossover sport van one of the quietest interiors in the segment, matching its rich appearance and attention to detail.
