Kelley Blue Book awards the Audi A5 a 4.3 out of 5 rating in its expert review. KBB describes the A5 as a sophisticated luxury car that does an outstanding job of balancing performance with daily usability. The publication highlights the available S line package, which adds more aggressive styling cues and a sport-tuned suspension, as a popular choice among buyers. According to KBB, the A5's 2.0-liter turbocharged engine is refined and torquey in everyday driving, with good low-end response that makes city traffic effortless and highway merging stress-free. The eight-speed automatic transmission replaces the previous dual-clutch unit in the latest models, which KBB says improves low-speed smoothness and civilizes the driving experience in stop-and-go traffic. The interior earns consistently high marks for its premium presentation, comfortable front seats with standard heated functionality, and excellent use of space in the sportback configuration. KBB cautions that the A5's optional equipment, including the 19-speaker Bang & Olufsen stereo and adaptive cruise control, can push the price well past $55,000 when fully loaded. Depreciation resistance is rated above average for the segment, and KBB's 5-Year Cost to Own projections compare favorably against direct German rivals.

Edmunds rates the Audi A5 at 8.0 out of 10, earning its 'Recommended' badge. Reviewers praise the upscale cabin, composed ride, and punchy turbocharged engine, along with the standard virtual cockpit and intuitive infotainment. The A5 proves a strong daily driver with good fuel economy, and the Sportback version offers a genuinely usable back seat and hatch. Criticisms focus on the high cost of options and a driving experience that is less engaging than the BMW 4 Series or Genesis G70. Overall, the A5's blend of luxury, technology, and all-weather capability makes it one of the most complete compact luxury cars on the market.
