The A4 sedan is the heart of the Audi lineup. The A4 is available in an impressive number of driveline configurations including 4-cylinder, V6 engines, FWD and AWD. All versions include Audi's decidedly German combination of handsome styling and mechanical prowess. The turbocharged four-cylinder and V6 models offer a lot of performance for the money. A long list of standard equipment includes a leather interior, MMI information interface, and a sunroof. Higher trim levels offer exclusive features like adaptive cruise control and LED headlamps. Sport and S-Line trim packages allow buyers to tailor the A4 to their tastes. As good as the A4 is, it competes in what may be the most competitive segment in the whole industry featuring standouts like the BMW 3-series, Infiniti G and the Lexus IS, all offering models in the low to mid 30s.

The 2.0l four-cylinder is now rated at 220-bhp.
