Introduction: After seeing the roads filled with M-Performance, AMG-line, S-line and R-versions for the premium brands, Infiniti has decided to make its move and invent a department for sportier versions of its vehicles. This is how the IPL (Infiniti Performance Line) was born. Engineers tried to work their skill on the G37 Coupe and, in 2011, they showed what was suppose to keep up with BMW's 335i Coupe, Merc's CLK 350 or Audi's S5 Coupe. They did manage to get right behind them, but not that close.

Introduction: Infiniti introduced in 2007 a new performance coupe built as a successor for the already aged G35.
