The story of the Infiniti QX80 is a little confusing. The SUV originally debuted for the 2011 model year as a replacement for the first-generation QX56, and it continued to carry the QX56 name. But when Infiniti decided to rename all of its SUVs, the QX56 became the QX80 for the 2014 model year. A full-size luxury SUV, the QX80 has three rows of seats and room for up to eight passengers. Furthermore, the robust V8 engine gives you plenty of power and towing capacity. Though Infiniti has kept the QX80 updated over the years, it is the elder statesperson of its class.
