Audi S4 acceleration

The previous B6/B7 S4s were the top-of-the-line models in North America, ahead of the 3.2L V6 and 4-cylinder 2.0T A4s, and competed with the BMW M3 which at the time had a high-rev 3.2 L inline 6. The 3.0 TFSI V6 engine replaces the 3.2 litre FSI V6 as the upgrade engine in the A4 and A6 lineups starting for 2009; both the 3.2 litre FSI and 3.0 TFSI were offered together until the end of the 2010 model year
