Buick has marketed its “QuietTuning” approach to designing cars since 2008 when the motif debuted with the first-generation Enclave. However, it’s not a blanket approach for General Motors’ other luxury brand Cadillac.
The Detroit Free Press reported on an in-depth look at QuietTuning and also spoke to Cadillac about how each approaches the luxury of silence. At Buick, the latter absolutely rings true. The brand works to keep the car hushed in nearly every respect. Whether it be noise from the powertrain, outside factors such as traffic, or road imperfections such as potholes that scatter across so many local roads.
Overall, QuietTuning combs over Buick vehicles in the tires, suspension, and other elements such as the windows. The latter use acoustic laminated glass, which is slightly thicker than regular glass to muffle sounds outside of the car. The suspension of each Buick model boasts coil spring isolators in the suspension, which work to deliver a smoother ride, while the shock absorbers are tuned specifically to stabilize the ride when the driver encounters an impact.
At Cadillac, some of the same approaches matter, but market research showed Cadillac customers wanted a different kind of experience. Per Ken Kornas, the Cadillac CT5 product manager, its research showed the brand’s customers wanted a quiet vehicle, but also wanted to hear what they wanted to hear. That includes piped-in engine tones to emphasize acceleration to emphasize performance and luxury. Kornas said Cadillac has a “curated library” of engine sounds it uses for its vehicles. The sounds are exclusive to Cadillac, but Buick wants no part of the artificial tones.
Instead, Buick will stick to the hushed library motif.
