Audi will unveil the S4 Sedan and Avant versions at the Paris Auto Show. Until we'll have the official images here's a pretty good idea of how the Avant version might look like.

The S4 will feature a modified bumper, a larger diffuser and a modified spoiler, same as in the S5. The RS4 will feature an even more aggressive design.

The 2009 S4 will be powered by the Audi’s all-new 3.0-liter supercharged V6 engine that will deliver around 330 hp.
