As the competition with the BMW 3 Series heats up, Audi has significantly updated its A4 sedan. This compact sport sedan includes such features like a turbocharged 2.0-liter four cylinder (with an available 265-hp V6), Audi's Drive Select system - which allows drivers to choose between three different driving modes, and various other standard luxury car amenities. Considered to be the brand's best seller, the A4 may just be one of the most perfect sport sedans on the market.

It combines luxury, performance, and everyday utility into one package. Not only is it powerful, but it's extremely tame when driving around town. Even with the standard four cylinder engine, there is no performance shortagefor those of you who have a heavy foot.
