2010 Audi S4

Audi lost the plot with the last generation S4. Unlike the twin-turbocharged V6-equipped B5, its B6 and B7 brethren did little to stoke the flames in our collective hearts. The "S" simply stood for, "I paid more for a bigger engine and some additional trim." Needless to say, that sort of behavior doesn't cut it when you're battling it out with one of the most competent sports sedan of the last decade: the BMW 335i.
