Two SUVs, but completely different in all significant aspects: fuel economy, maximum occupancy, model year, starting price, horsepower, ground shadow size, and height. First of all, the 2014 Nissan Armada is priced $4,310 lower compared to the base MSRP of the 2016 Lexus RX 350, which is newer by two model years. Also, the 2014 Armada has a more powerful engine than the 2016 RX 350, and it gets 8 fewer miles on a gallon of fuel. In addition, not only RX 350 is slightly smaller, but it's also shorter than the Armada. And finally, the Nissan Armada seats three more passengers than the Lexus RX 350. Among similarities is the body structure.
