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. Base FWD models come with a 1.8-liter engine, which delivered a respectable 27 mpg in our tests. The car has ample power once underway, but it can feel flat off the line. AWD versions have a stronger 2.0-liter turbo engine. Gripes include an infotainment system that takes time to master and a tight rear seat. 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. First-year reliability has been average.
