Infiniti EX Concept Preview – New York Auto Show: OK, so maybe there are enough smallish luxury-type crossovers to build a bridge across the Atlantic. And we would agree that the last thing needed on this side of the Pond is a swoopy import CUV. But wait…hold on for just a second. There may be room enough for just one more, if that one is the Infiniti EX Concept. Debuted as a concept vehicle at the 2007 New York Auto Show but with a date for production later in the year, the Infiniti EX Concept looks to give the Acura RDX and the BMW X3 a hard time, with a more powerful engine and a list of innovative safety technology devices.
