This generation of S4 was based on the B6 Audi A4, and was offered as a sedan, convertible, and 'Avant' station wagon. The B6-based S4 was fitted with a 4.2L V8 engine and was the top of the line variant available for the B6 Audi A4 as no RS4 variant was offered. The 2008 S4 was the top-performer model in the Audi A4 range. It was introduced in late 2008 as a 2009 model and it lost the 4.2-liter naturally aspirated V8 in favor of a supercharged 3.0-liter V6.
