With so many cheap MP3 players around today, people have gotten used to poor-quality sound, so a ride in the 2011 Audi A4 will be an ear-opening experience. The optional Bang & Olufsen audio system, at $850, is worth every penny, as it delivers a sublime musical experience. You may think you've heard the music of Katy Perry, Lady Gaga, or The Black Eyed Peas, but play their tracks in the A4 and it will open up a whole new world.

We found other great attributes of the Audi A4, such as the navigation system with its textured, 3D maps, and the phone system, which as dial-by-name voice command. Quality materials make the cabin a comfortable place to sit through slow commute traffic.

Its direct-injected turbocharged engine is also a modern power plant. It may not be a fire-breathing monster, but it gives the A4 all the push it needs. And the new eight-speed automatic transmission makes for economical freeway driving.
