The Audi A4 represents a line of fantastic sports sedans. They deliver crisp handling, a firm ride, and a well-controlled suspension that make for a precise, high-quality driving experience. The A4 feels like it's on rails around fast sweepers, especially when equipped with Audi's quattro all-wheel-drive system, one of the world's best. Beautifully finished interiors exude quality and ergonomic excellence.Performance and driveability vary by model. The turbocharged four-cylinder engine that comes on 1.8T models delivers excellent performance when paired with a manual gearbox and it's attractively priced, but the 1.8-liter engine doesn't work as well with the available automatic transmission.

The V8-powered S4 delivers awesome performance and serious enthusiasts love it, but its suspension may be too firm for most drivers.Click here to read more
