Mixed to negative sentiment overall, with a clear divide between appreciation for traditional Audi virtues and significant criticism of its execution as an electric vehicle. The vehicle is consistently praised for its quiet, refined ride quality, comfortable and supportive seats, solid build quality with minimal rattles, and familiar, ergonomic interior layout with physical HVAC buttons.
