The Infiniti FX Performance Concept is designed based on the Infiniti FX Crossover with the help from Formula One World Champion and Infiniti FX driver Sebastian Vettel. This is the first image of this the FX Concept released by Infiniti which will make its world debut at the Frankfurt Motor Show in September, 2011. From the look at the first released image of the Infiniti FX Concept, one can see that the Infiniti FX skirts are replaced by carbon parts. A roof spoiler can be seen from the rear bumper which also appears to be in carbon. The rims look different from the OEM rims as well as the front bumper.
