Two SUVs, but completely different in all significant aspects: fuel economy, model year, starting price, horsepower, ground shadow size, height, and maximum occupancy. First of all, there is a $5,010 difference in the base MSRP. The 2016 INFINITI QX60, a newer vehicle by two model years, has a higher starting price than the 2014 Nissan Armada. Also, the 2014 Armada has a more powerful engine than the 2016 INFINITI QX60, and it gets 8 fewer miles on a gallon of fuel. In addition, the INFINITI QX60 body is slightly smaller than the Armada, and in addition to that, it's also shorter. And finally, you'll seat one more passenger in the Nissan Armada than in the INFINITI QX60. Among similarities is the body structure.
