It's hard to believe, but 2013 marks the sixth model year for the Audi S5 (it launched as a 2008 model). I've loved this coupe since the day it debuted, but if I'm honest, the thing that really made the S5 special at launch was its awesome 4.2-liter naturally aspirated V8. You know, the one from the old RS4. And the R8.
