http://www.edmunds.com/insideline/do/Drives/FullTests/articleId=125872 --- It would be easy to dismiss the 2009 Infiniti FX50 as completely irrelevant, a mutant crossover vehicle. Going on past sales figures alone, you'd be right, because total 2007 sales of the Infiniti FX45 numbered just 1,598 units, about a tenth of the 2007 Infiniti FX35s that found their way to the street during the same period last year. But this wouldn't be entirely fair. The all-wheel-drive FX came to market in 2003 as one of the first crossovers that had morphed into a high-performance vehicle — a kind of personalized coupe, only with cargo capacity. The FX looked like a Bionic Cheetah, showcased some segment-leading technology and delivered road-going performance on par with European-brand sport-utilities the BMW X5 and Porsche Cayenne. Unfortunately, no one seemed to care. Yet now people are talking about personal-style crossovers. Have times finally caught up with the 2009 Infiniti FX50?
