I spoke to somebody about that at Infiniti and there won't be no IPL FX coming out atleast anytime soon. There just isn't no profit gain in it because the current 2012 models are doing terrible in sales. IPL is just getting started and if it goes to anything it would be a performance car like the G.
It will be interesting to see how the 2013s sell. Disclaimer here...I don't know much about the car business but it seems that dealers have large stocks of 2012s and 2013s are rolling in. Infiniti announced the 2013 engine change in June so it seems they may have messed up the 2012 sales??? When did the 2012s come out last year?
