( http://www.TFLcar.com ) The 2013 Infiniti JX is the latest Crossover vehicle to be added to Nissan's luxury car brand. Unlike the sporty FX35/FX50 twins, the 2013 Infiniti JX has three rows of seating and room for seven. The new LX will share a platform with the upcoming new Nissan Pathfinder and features the brand's now familiar V-6 engine. We had the chance to see what makes the Infiniti unique from competitors like the Acura MDX at Denver's Auto Show.
