2007 Audi RS4 vs. 2008 Lexus IS-F
Lexus would like you to believe that the 416-horsepower IS-F will have a similar impact on the market for over-endowed hot-rod sedans that is dominated by the Germans. The “F” suffix for this new variant of the IS is a nod to the early days of Lexus, when “F1″ became the code designation for the LS 400 prototype.
