Conceived in the bigger-is-better school of SUV design, the 2009 Infiniti QX56 takes its job as a full-size luxury hauler very seriously. Available in a single upline trim level, this body-on-frame design is based on Nissan's Titan pickup platform but shares styling and engineering basics with its cousin, the Nissan Armada. In addition to a powerful V8, rear- or four-wheel drive configurations and class-leading towing capacity, the 2009 QX56 features a plush cabin with standard seating for seven or eight. An abundance of luxury appointments makes this mammoth Infiniti the only import-badged luxury SUV with the scale, features and capabilities to compete directly with big domestic models like the Cadillac Escalade ESV, GMC Yukon XL and Lincoln Navigator L, while fending off other international nameplates, including the Audi Q7, Mercedes-Benz GL 450 and the Lexus LX 570.
