The Audi A4 remained highly competitive. In fact, this A4 was nearly everything a compact sports sedan should be. It has a solid, high-quality feel and the interior is exquisite. Agile handling makes it fun to drive and the ride, though quite firm, is supple and controlled. The cabin is quiet unless you ask the turbocharged four-cylinder engine to work hard.
