Cars.com Family Reviews the 2012 Infiniti QX56
The luxurious three-row 2012 Infiniti QX56 can easily handle larger families with its seating for up to eight passengers, according to Cars.com Family contributor Courtney Messenbaugh. Its 400-horsepower V-8 engine can tackle mountain passes, but you'll pay for all that power at the gas pump. The QX gets a paltry 14/20 mpg city/highway, and it cost Courtney $100 to fill the gas tank. Ouch.
