Interior Noise

With an as-tested price topping $56,000, we expected a quiet luxury car, and to some degree, that’s what we got. In regular traffic, exterior noise was nicely isolated, allowing the STS’s passengers to enjoy some peace. But when the driver dials things up a notch, the decibel level climbs proportionately. Our tester featured 18-inch summer performance tires that are designed for handling and not a quiet ride, a point we recognized instantly. Wind noise was kept to a minimum, but the powerful V-6 engine sounded raucous and unrefined at higher revs, stealing much of the big Caddy’s luxury aspirations.
