The Japanese domestic market [JDM] Nissan Skyline, which the rest of the world knows as the Infiniti G37 sedan, is the latest car to capture the attention of Wald International.

The renowned Takatsuki-based tuning firm has presented a Sports Line Black Bison Edition package for the saloon model consisting almost entirely of cosmetic upgrades.

Being a luxury carmaker is all fine and dandy but if don’t have your own performance division, you haven’t really made it to the major league. BMW has the M Division, Mercedes-Benz has AMG, Audi its RS and S lines while even luxury-oriented Lexus has the “F Sport” range to show for itself.

Infiniti’s answer to all these acronyms is IPL, which stands for Infiniti Performance Line. With just one model though, the IPL G Coupe, it’s not really a line, is it? Therefore, the Japanese carmaker chose the 2011 LA Auto Show to unveil its second production IPL model based on the G37 Convertible.

Nissan's luxury arm is doubling its Infiniti Performance Line [IPL for short] lineup with the addition of the new 2013 IPL G Convertible that we first saw in concept form at last year's Paris Motor Show.

IPL is Infiniti's answer to the in-house tuning divisions of its German competitors such as Audi's S brand, BMW's M department and Mercedes-Benz's AMG branch.

Scheduled to reach the market in spring of 2012, the convertible model follows the IPL G Coupe that went on sale in the States in December of 2010.
