Audi's A3 is a compelling entry-level luxury car, but it lacks some expected features for its price and the interior feels austere. It's solid, quiet, and has a drum-tight body structure. Crisp handling and a firm, controlled ride make it enjoyable to drive. We tested the A3 with the now-discontinued 1.8-liter engine, which delivered a respectable 27 mpg in our tests. The cabin is quiet and the front seats are comfortable and supportive. The rear seat is tight. It takes a bit of time to get used to the MMI infotainment system, but it ultimately proves logical. It's easy to hit $40,000 with just a few options. A sporty S3 with a 292-hp 2.0-liter turbo, a convertible, and a hatchback plug-in hybrid are available.
