Southern California is plagued by grooved, concrete highways that could make complainers out of the deaf – they really are that bad. So when we drove the Aveo on said highways, we weren’t entirely shocked to discover good doses of road and tire noise. When we drove Chevy’s least expensive car on smooth paved roads, the tire and road noise lessened dramatically, though not to the point of disappearing. Furthermore, by cutting out much of the road and tire noise, our ears were better able to notice the wind noise. Whatever the road surface, the high-strung four-cylinder engine’s song is always readily heard, yet its refinement is no better or worse than most others in the segment.
